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.

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.

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.

This allows for customizing the panel that is selected by default when
calcurse is started.
Note that this patch doesn't add any documentation. Also, this
configuration option currently cannot be configured using the
configuration menu.

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.

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.

Remove the export bar and use a simple status_ask_choice() dialog
instead. This reduces code complexity and replaces another unnecessary

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.

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.

Instead of calling type-specific duplication handlers and inserting
clones of the original items when pasting, save the generic day item and
remove the actual item from the linked list, so that it can be inserted
anywhere else later.
The cut/paste buffer is moved to the interaction unit, item-specific cut
operations are changed to remove the item from the linked list only
instead of copying and freeing it. An item is only freed if another item
is cut before the current cut/paste buffer is pasted. All paste
operations are changed and reinsert the actual item instead of creating
a clone.

This is a first step to clean up several compilation units and separate
the front end from back-end operations. All functions that require user
interaction are moved to a new compilation unit "interaction.c". Also,
following things are adjusted to the new layout:
* Make day_item_get_*() and a few other functions public, so that it can
be accessed from the new compilation unit.
* Use apoint_hilt(), todo_hilt(), etc. instead of directly accessing
static variables.

Pass the recurrent appointment itself instead of passing a date and an

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.
