Check if the appointment panel contains any items and unset the
highlight counter if it doesn't. Not doing this resulted in core dumps
if the edit command was invoked after switching to a day without any
appointments/events.

After BUG#6 had apparently been closed with the screen locks introduced
in commit a80f8dcf2c6eb3b54658218bc081ee9694204dd5, some people still
had problems with random characters appearing in the notification bar.
This was obviously caused by wgetch() refreshing the screen if the
status panel was changed. From wgetch(3):
If the window is not a pad, and it has been moved or modified since
the last call to wrefresh, wrefresh will be called before another
character is read.
Since the wgetch(3) isn't thread-safe, there were race conditions
between the notification bar thread drawing to the notification bar and
wgetch() updating the screen. Introduce a (hidden) window that handles
all key presses and never gets changed in order to avoid this.
Also, call wins_wrefresh() explicitly in status_mesg(), since we can no
longer rely on wgetch() updating windows automatically.
Fixes reopened BUG#6. Note that this is a hotfix -- FR#26 has been
opened to ensure we fix this properly in the next major release.

The slave window array was just big enough to hold a single element,
whereas two elements are written/accessed. Fix this off-by-one error in
the array declaration.
Note that this messed up the panel layout when using clang as a
compiler.

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.

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.

This is kind of useless since users are not able to react to an
auto-save notification. It also causes all kinds of problems if the
status bar is in a non-standard mode (message, prompt, ...) and is prone
to race conditions if the status bar is updated by another thread at the
same time.

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.

Break up the big switch statement into several functions. The functions
are declared inline to avoid unnecessary function calls.
Also:
* Add a "KEY_HANDLER" macro can be used as a short version of a "case"
statement, followed by a function call.
* Declare several state variables global to avoid having to pass them to
each of the new handlers.
* Pass the pressed key to each of the handler functions in order not to
break handlers that handled more than one key before the handlers were
pulled out.
These three changes were introduced to keep this patch as atomic as
possible and are intended to be removed in following patches.

This adds support for vim-style copy/paste registers which allows
cutting and copying multiple items without having to overwrite the
copy/paste buffer. Registers can be specified using the quote key ('"').
To access a register, type '"x' before a command where "x" is the name
of a register. If you want to copy the currently selected item into
register 1, type '"1c'.
Valid registers are 0-9, a-z, "-" and "_". Note that the latter is the
so-called black hole register, which works similar to the black hole
register in vim.
The register prefix key is currently hardcoded and cannot be configured.
