Recurring appointments do not show up in the notification bar as next
appointment. This was partly corrected by 2084f35 (Fix notification of
recurrent appointments, 2017-02-09) and 5aa7a09 (Fix another error in
the notification code, 2017-02-11).
The search function recur_apoint_starts_before() had a wrong second
argument, but is really of no use: the start time of a recurring
appointment is the start time of the very first occurrence (in the
past). A comparison against the item in the notify_app structure tells
nothing of the start time of the current day; at most it eliminates some
future recurring appointments. The function can be dropped, and the
entire recurring appointment list looked through.
The proper start time is found in the main search loop (and called
real_recur_start_time) and must be compared against the item in the
notify_app structure.
But because recur_apoint_find_occurrence() is limited to a particular
day (second argument), two searches are necessary to cover 24 hours.
Unrelated cleanups: removed function return value; changed long to
time_t.

The configuration settings for calendar view (monthly/weekly) and todo
view (hide/show completed) used to be saved automatically on calcurse
exit, with values taken from the current interactive settings. They
could not be set explicitly in the configuration menues. Configuration
settings are no longer saved on program exit, but on exit from the
configuration menu. This means that the saved values are those that were
current when the configuration menu was entered. To change a saved
value, you must set the view as desired and then enter/exit the
configuration menu.
The preferred calendar and todo views are no longer automatically taken
from the interactive settings, but are explicitly set in the general
options menu. Default values are monthly view and hide completed view.

The invert filter option is automatically set for -P (and cannot be used
on the command line). The intention is that the grep option (-G) is used
to find the items that should be removed. To remove them, the same
command is run with -P instead of -G.
In general, purge will remove matching items (silently).
Backward compatibility for option -F (no invert filter).

New filter option: --filter-invert. When present it inverts (negates)
the other filter options combined. This is mostly useful with the -G
option (with -Q the output is limited by the query range (day range)).
The ouput from "calcurse -G <filter options>" is the (set) complement of
"calcurse -G <filter options> --filter-invert". Here <filter options>
may be any combination of filter options.

An earlier commit ("CLI: take input date format from configuration file,
do not accept time") replaced parse_datetimearg() with parse_datearg()
and eliminated time-of-day from command line date arguments. This made
the full use of filter options impossible.
That earlier commit is reverted and updated. The parse_datearg()
function is replaced by an updated parse_datetimearg() function that
- takes the date format from the configuration file
- accepts date, date-time or time
The updated parse_datetimearg() function has been extended to report
back the type of the date string received in order to set (filter)
options correctly. Input dates for query ranges (--from, --to, --days)
are still limited to dates only.

The key_generic_command() function provides a "safety exit" in case of
online changes that should be dropped at exit when auto_save is on, or
(NEW) should be saved at exit when in read-only mode. A check for
unsaved changes has been added. The command prompt has been extended
with minimal help information.
After commit 05e0fd0 "Quit, autosave and interactive save" you could not
leave calcurse in read-only mode with the quit command because the
key_generic_quit() function interpreted IO_SAVE_CANCEL as a decision (by
the user) to cancel a save-conflict and cancelled the quit as well. Now
the function will quit unconditionally in read-only mode (as stated in
the man page). In normal mode a check for unsaved changes has been added
in case auto-save is off.

With the exception of filter.type_mask, a filter is only applied if set
explicitly on the command line with a filter option. Whether that is the
case, is determined by comparison with the initialization value. For
date related filters (start_from/to, end_from/to) that is -1, hence the
criterion is != -1, not >= 0.
In generel, a filter initialization value should be invalid (i.e. one
that cannot be set explicitly). As times before the epoch (1 January
1970 00:00:00 UTC) are negative, -1 is a valid Unix time. However, as it
cannot be set from the command line, it is probably no problem?

Explanation. There is an important difference between "to <date>" (e.g.
to 15/11/2018) and "to <date time>" (e.g. to "15/11/2018 13:30"):
<date> is a time span (of 24 hours), while <date time> is a point in
time.
"To <date>" really means "to the end of <date>", while "before <date>"
means "before the beginning of <date>". There are 24 hours between the
two, whereas there is only one second between "before <date time>" and
"to <date time>". Similar for from/after.
An earlier commit introduced parse_datearg() that only accepts a date
without a time. Hence, a date should be treated as a time span from
midnight to one second before next midnight.
The commit also fixes an error detection bug (filter.start_from/to and
filter.end_from/to were updated too early).

Before this patch the input date parsing accepts three formats:
yyyy/mm/dd, mm/dd/yyyy, yyyy-mm-dd. They are tried in sequence. It also
accepts an additional time (hh:mm), or a time without a date.
There are several issues with this:
- it is not documented
- the date format dd/mm/yyyy is not accepted
- print_date() and filter option settings (in parse_args()) can only
handle midnight times (which are the result of a date without time)
- it is highly uncertain what happens if a time (without a date) is
given; at least the -d option treats a time without colon (1215 for
12:15) as a number
It seems that acceptance of time input is a by-product and not needed.
For these reasons the input date parsing has been changed:
- the format is taken from the configuration file (as is the case for
the output date format)
- only a date, and no time, is accepted
Because the input date format is used during parsing of the command
line, the configuration file must be loaded first, i.e. the options -D
or -C must be parsed before the remaining ones. Loading the
configuration file may result in errors (e.g. caused by changes between
versions). For this reason config_load() has been made more tolerant and
issues warnings instead of exiting.
A followup patch will introduce two options to allow the configuration
file settings to be overridden for input and output date formats.

In "--from a --to z", a is included in the range, z not. This is
non-intuitive and disagrees with the semantics of "to" in filter options
like --filter-start-to, where "to" (and "from") are used inclusively (as
opposed to "before" and "after"). It also has the effect that "--from
today --to tomorrow" has a range of 1 day, "--to z" a range of 0 days
(otherwise not allowed), and "--to today --days -1" is allowed and
displays yesterday!
The implementation has been fixed to agree with "inclusive" semantics.
Options --from and -days with negative range are allowed, while --to and
--days are disallowed also when the range is negative.

The introduction of the "-C <confdir>" option is an opportunity to
review the initialization of data paths. It lead to a rewrite.
Two "root" directories are used (data and configuration files); by
default they are identical. The statically allocated path buffers are
turned into dynamically allocated buffers.
Missing files/directories now include hooks.

The number of seconds in a day and daylength in seconds differ when
Daylight Saving Time is in effect on two days of the year. The day when DST
takes effect is 23 hours long, and the day when DST ends is 25 hours long.
In the latter case the date changing thread wóuld enter a loop in the last hour
before midnight (in the former it would set the date an hour too late).
The next midnight is calculated through mktime(), invoked by date2sec().
Wrong daylength prevented appointments from being stored in the day vector and
caused them to be displayed wrongly in the appts panel.

Calcurse saves time and date information on disk as local time in readable text
file format. When loaded from disk or when entered by the user, local time is
converted to Unix time (seconds since 00:00:00, 1 January 1970). When
displayed, and later when saved to disk, the Unix time is converted back to
readable local time. Both conversions depend on DST.
Hence, if midnight for a day with DST in effect (i.e. local time) is converted,
increased with an amount and converted back, the amount has changed if DST is
_not_ in effect for the resulting time. In general, calculations on Unix time
variables should be used with caution because of the DST-dependent conversions.
Instead, the calculations should be performed on local time data with the help
of mktime().
The commit fixes start time for pasted appointments (ordinary and recurrent)
and the 'until'-date of recurrent appointments, pasted as well as new and
edited. The latter problem is slightly different in that the adjustment is a
number of days, as it is for exception dates.
Update of the date in parse_datetime() has been corrected to be similar to
update of the time, although no problem has been identified.

The screen and user interaction is managed by the main thread. Other parts of
calcurse (threads) wishing to use the screen or communicate with the user, must
do it via the main thread.
For this purpose the main input loop is extended with a message queue. A thread
may insert a message in the queue. The main thread tests for messages before
listening for user commands. If a message is present, it is displayed (in a popup
window) for the user to acknowledge. Depending on the message other actions may
be performed, e.g. the message could be turned into a "system appointment/event"
and inserted among the usual appointments.

A complete save or reload operation is made up of several cooperating lower
level function calls. In stead of protecting the lower level read or write calls
on the data files, the entire save or load operation is protected in order to
ensure its integrity.
Thus mutex protection has been moved from the level:
io_load_data(), io_merge_data(), new_data(),
to two functions at the higher level:
io_save_cal(), io_reload_data().
The protection includes pre- and post-hooks.
The function io_load_data() needs no protection when calcurse starts up
(threads not yet started) or runs in non-interactive mode (no threads involved).

The function io_save_cal() saves apts, todos, configuration data and key
bindings. The configuration and key files do not belong with the two data
files, but the progress bar function assumes that all four files are saved in
a fixed sequence. Since it is used nowhere else and contains unused parts,
the function has been removed.
A return code for file access error is introduced, and the EXIT macro moved to
the command level in calcurse.c.

in commit 0124618, A save refinement: no action if everything is unchanged.

Moving user information to calcurse.c makes it easier to perform the actual
save/reload operatons in io.c, e.g. it is possible to load instead of
reload after a merge in conflict resolving.
The save/reload operations are of such importance that the user should always be
informed of the result (it's a bit disquieting when there is no reaction to a
save or reload command). Hence, the save/reload status messages are no longer
conditioned by show_dialogs(). No confirmation is asked for, so a message stays
until the status bar is updated by another action.
Care is taken to inform about save/reload actions that result in no change.
Texts are kept concise because of the limited message area. When conflicts are
present, whether saving or reloading, the "continue/merge/cancel" pattern seems
easier to grasp.

A reload action will do nothing if in-memory data as well as data files are
unchanged. This commit accomplishes the equivalent for a save action.
Because saving of configuration data and key bindings are mixed up with saving
of data files, any changes in those will only be saved if data files also have
changed. Hence, configuration data and key bindings are also saved upon exit
from the configuration menu.

This is a replacement for commits 57dd3d6 and 912124b.
The idea is to move the check for modified files and the list initialization
into io_load_data(), and let io_load_data() decide what to load. A new
argument is used to force a load.
The return code from new_data() (the renamed version of
io_check_data_files_modified()) tells which files have changed.

After resolving a save conflict with the merge tool, a save operation has,
in effect, occurred, and data files must be reloaded to import the result of
the conflict resolution.
This is a replacement for commit 2fe9c7e. The operations concerned with the user
interface are kept out the io-operations (as in all other cases) and take place
at the command-level in calcurse.c. and not at the io-level (io.c).
