Add a configuration option that allows for switching to compact panel
mode. In this mode, all window labels are hidden, so that there's more
space for actual information.
This patch doesn't add a configuration menu entry and doesn't add any
documentation.
Implements FR#7.

We did not setup a thread cleanup procedure which resulted in calcurse
freezing if a thread tried to draw on the screen after another thread
was canceled while locking the screen.
Note that this kind of cleanup handlers should be added to other mutexes
as well. This patch just removes the most common case of triggering a
deadlock.
Also note that we cannot move pthread_cleanup_push() and
pthread_cleanup_pop() into the locking/unlocking functions since both
pthread_cleanup_push() and pthread_cleanup_pop() may be implemented as
macros that must be used in pairs within the same lexical scope.

Lock the screen if either the calendar panel or the notification bar is
updated to avoid race conditions.
Addresses BUG#6.
Note that we currently always use a screen-level lock, even if only one
window is affected. This is to be changed in the future.

Since the result of localtime() is stored in a statically allocated
structure, data was overwritten when a context switch occurred during
(or shortly after) the execution of localtime(), potentially resulting
in critical data corruption. BUG#7 and BUG#8 are likely related.
This patch converts all usages of localtime() with localtime_r(), which
is thread-safe.

Add a very simple cache, which is used to store the days that contain an
event or an appointment. This makes redrawing and browsing the calendar
panel much faster.
The cache has a size of 31 integers (which is equivalent to 124 bytes on
a 32 bit system and 248 bytes on a 64 bit system) and invalidates itself
if the current month has changed. If an item is added/changed/removed,
the cache needs to be invalidated manually by calling
calendar_monthly_view_cache_set_invalid(). Note that this will always
invalidate the whole cache, even if only one item at the last day of the
month was removed. This is a trade-off between simplicity and
efficiency.

In addition to generic key bindings for moving one day (week)
forward/backward, define similar bindings for moving a month or a year.
Of course, count prefixes are allowed here as well.
Also add status bar hints and help texts.

When we only want to display a string at a specific place of the
screen, there's no need to use the more complex mvwprintw(), use
mvwaddstr() instead.
This should be slightly more efficient, and, above all, it prevents
weird things to happen if our string contains a '%', being interpreted
as an unwanted format string.

Some strings are initialized without wrapping them in _(); instead,
_() is applied on the variable when it is used.
This is incorrect, since these strings don't get added to the catalog.
Fix that by applying _() only once, when the string is declared.

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.

Add the "const" keyword to parameters and variables that are never
modified. Most of these were spotted by "-Wwrite-strings".
We cast the second parameter to execvp() explicitly as it expects a
"char *const[]" where it should expect a "const char *const[]"
(according to the documentation, this is due to compatibility reasons).
This should be changed once we come up with a better solution.

The bzero() and bcopy() functions are deprecated and were removed from

We added count prefix support to motion commands in commit
59e006e56d but obviously forgot to check
whether the range checks in calendar_move() still work correctly.
Refactor out range checks and replace them by a single check that is
performed *after* the new date is computed, but before we assign the new
value to the actual selected date. This ensures we won't have to bother
about these again when changing/adding functionality in/to
calendar_move(), while keeping performance (date_change() is pretty
cheap and range violations are corner cases anyway).

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

should fix what's left:

Short forms are only accepted in interactive mode (e.g. when using the
"Go to" function, editing a recurrent item's end date, and so on).
Samples: "1/1/30" for "01/01/2030", "26" for the 26th of the currently
selected month/year or "3/1" for Mar 01 (or Jan 03, depending on the
date format) of the currently selected year.
