The purpose is to make child_wait() reliable. The handler is meant for
the notify main thread, but signal handlers are shared by all threads.
In the calcurse main thread and the periodic save thread (hooks) the
handler and child_wait() will compete (if the signal handler kicks in
first, the waitpid() call in child_wait() will fail with errno ECHILD).
All child processes in the main thread, the notify thread, the periodic
save thread and the notify demon are explicitly waited for.

In an effort to better integrate the import process with external
applications, it's desirable to have a mechanism by which external
programs can trigger a reload of calcurse's data.
This patch adds that functionality via SIGUSR1. The reload request is
handled in the main loop. When the user is currently entering data, the
request is delayed until the main loop is re-entered.

This completes our switch to the Linux kernel coding style. Note that we
still use deeply nested constructs at some places which need to be fixed
up later.
Converted using the `Lindent` script from the Linux kernel code base,
along with some manual fixes.

Disable signal handlers in wins_prepare_external() and reactivate them
in wins_unprepare_external().
Before, it was possible that resizing the window during editor/pager
mode resulted in the calcurse main screen appearing on top.
Addresses BUG#9.

SIGWINCH isn't POSIX-compatible and causes a compile error on several
platforms, such as OpenBSD:
sigs.c: In function 'generic_hdlr':
sigs.c:63: error: 'SIGWINCH' undeclared (first use in this function)
sigs.c:63: error: (Each undeclared identifier is reported only once
sigs.c:63: error: for each function it appears in.)
sigs.c: In function 'sigs_init':
sigs.c:97: error: 'SIGWINCH' undeclared (first use in this function)
*** Error code 1
Define "_BSD_SOURCE" explicitly in this compilation unit to enforce
definition of the "SIGWINCH" constant. Also, set "__BSD_VISIBLE" to 1
since FreeBSD doesn't honor "_BSD_SOURCE".

Convert our code base to adhere to Linux kernel coding style using
Lindent, with the following exceptions:
* Use spaces, instead of tabs, for indentation.
* Use 2-character indentations (instead of 8 characters).
Rationale: We currently have too much levels of indentation. Using
8-character tabs would make huge code parts unreadable. These need to be
cleaned up before we can switch to 8 characters.

* "WAIT_MYPGRP" isn't POSIX'ish. Relying on this caused compilation
issues in certain environments (e.g. under Cygwin). As a workaround,
define "WAIT_MYPGRP" explicitly if it's undefined.
* "P_tmpdir" is an XSI extension. Don't try use it if it isn't
available.

Use this constant everywhere when referring to a null pointer instead of
casting 0 to various types of pointers. Created using following semantic
patch:
@@
type type;

- (type *)0

A small style fix that removes all remaining "(void)" casts. Using these
isn't encouraged in GNU coding guidelines and doesn't serve a certain
purpose, except for satisfying a few static code analysis tools. We
already nuked some of these in previous patches, but this semantic patch
should fix what's left:
@@
identifier func;
@@
- (void)func (
+ func (
...);
Long lines were re-formatted manually.

Use a global flag to record whether the terminal was resized instead of
redrawing everything each time a KEY_RESIZE is read.
Add some additional checks to help_write_pad() as invalid actions may be
passed now due to using signals instead of virtual key presses.
