Previously an error from the character input routine wgetch() was
silently ignored. It should still be ignored, but must explicitly be
detected in order to be ignored. The issue came up in connection with
terminal window resize. For whatever reasons ncurses returns ERR (as
well as KEY_RESIZE) when wgetch() asks for input after a resize.

The window was not deleted if an "already in use"-key was detected,
and a new one was created as the loop was reentered.
Create/delete of the popup are moved outside the loop.
A redrawwin() call is needed to have the window displayed again.

Make sure that in cases when the date and time formats conflict, such as
is the case with "0030", the input is interpreted as a time value, not a
date.

In parse_datetime() it was possible to enter any number of dates and
times in any order. Allow just date or time or date followed by time.
Time must be looked for before date because of conflicting time and date
formats.

Add a wrapper around parse_date() which picks the current input date
format as well as the currently selected day and passes both values to
parse_date(), alongside with the parameters passed to
parse_date_interactive() itself.

All key names for ordinary ASCII keys as well as for escape keys (pseudo
keys) are cached in a lookup-table, keynames[], at startup. Mapping
between key names (strings) and key codes (integers) in keys_str2int and
keys_int2str) is performed through this table.
The key names used are those returned by the keyname() function of
ncurses. But to accommodate some of the names to the three-letter space
available in the status menu, four ordinary keys and the most common
escape keys have calcurse abbreviated names: ESC, TAB, RET, SPC and LFT,
HOM, PgU, INS, F1, etc.
All keys known by ncurses can be bound. Thus the check for not
recognized keys in the key configuration menu becomes superfluous. The
only keys that cannot be bound, are those escape keys not known to
ncurses, i.e. not described by the terminfo database for the terminal
type in use.

Code point mapping adjusted for multibyte characters to avoid the
ncurses range 0-KEY_MAX.
This includes three fixes:
1) test sequence in keys_assign_binding(),
2) reassemble multi-byte character in keys_wgetch(),
3) check for already in use in keys_assign_binding().
Rearrangement of code. The introduction of allocated memory in
keys_int2str() has as a consequence that check for recognized ncurses
pseudo characters now are in two places: keys_str2int() and
custom_keys_config(). The latter was moved from keys_wgetch() to improve
user information.
More informative warning messages in custom_keys_config().

The week number in the calendar panel is calculated according to
ISO 8601. Hence, Monday is the first day of the week and the
week number changes from Sunday to Monday.
However, calcurse ties the week number not to Monday, but to the
first day of the week as configured for display. Thus, when Sunday
is shown as first day of the week, the week number is correct for
Sunday, but wrong for the rest of the week (one behind).
With this patch the week number always follows the mon-sun week as
required by ISO 8601. A side effect is that when Sunday is displayed
as first day of the week, and Sunday is the selected day, the week
number displayed is invalid for the rest of the week (but changes
to the correct one when the selected day moves forward).
This raises the question whether the week numbering scheme should
follow the "first day of the week" choice and use the American week
numbering scheme instead of ISO 8601 when Sunday is the first day
of the week. But that is for the future.

When reading the data files, compute a cryptographic hash of the file
contents and store it. When saving the files later, ensure that the hash
still matches the current file contents. If it does not, show a warning

When introducing the fmt_day_heading() function in commit d56cc7a (Make
heading in appointments panel configurable, 2017-08-19), we forgot to
initialize the dynamic string. This resulted in calling mem_free() with
a garbage pointer, potentially resulting in a segmentation fault. Fix
this by calling string_init() before using the string.

A new function keys_wgetch() reads full UTF-8 characters instead of
single ASCII characters only.
Key bindings for regular ASCII characters are stored in a hash map while
the actions of keys with higher code points are stored in a linked list
for space efficiency.
The key serialization methods are updated to handle UTF-8 characters as
well; extended UTF-8 characters (characters not in the ASCII range) are
serialized by using the hexadecimal representation of the corresponding
code points (e.g. "U+00E4").

In the appointments panel, an appointment has a '-' to mark the time
span, and the description on the following line is slightly indented.
When the appointment is changed into a recurrent one, the '-' is changed
to a '*', making it easily distinguishable but the description also gets
a '*', thus breaking the pattern. Drop the extra '*'.

When checking whether an appointment belongs to a given day in
apoint_inday(), the return value was 0 if the end time of the
appointment matched 00:00 on that day (because we do not want to include
appointments starting on the day before and lasting until midnight).
However, this means that punctual appointments at 00:00 were not
included in any day. Fix the apoint_inday() logic to take this into
consideration.

When adding a key already in use for another action, a warning box is

The pair_content() function can be used to retrieve a color pair. The
foreground and the background color numbers are written to addresses
specified by the second and third parameters. While both parameters were
optional in older ncurses implementations (making it possible to pass
NULL pointers if the one does not care about either foreground or
background color), recent implementations seem to assume that both
parameters are valid pointers. Thus, instead of passing NULL, we need to
pass a pointer to a dummy variable when we do not care about the
background color.
Partly fixes GitHub issue #31.
