Use following macro instead of "sizeof(x) / sizeof(x[0])" everywhere:
#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))

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.

From the Linux kernel coding guidelines:
Do not unnecessarily use braces where a single statement will do.
[...] This does not apply if one branch of a conditional statement
is a single statement. Use braces in both branches.

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.

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.

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.

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.

We don't need floating point precision if results are casted back to
integer. Instead, rearrange operations and do the integer division after
the multiplication.
Version numbers are terminating decimals anyway and can be stored using
two integers without losing any information.

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.

This allows for specifying an editor or a pager with additional command
line parameters, such as "vim -e". Instead of interpreting "vim -e" as
an executable file, we leave it to the shell to tokenize and parse the
editor command now.

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.

Use percentage-based widths internally. This slightly impairs (user)
feedback but brings the sidebar configuration menu closer to the actual
configuration format (the user now configures percentage-based widths,
not absolute width values). As a bonus, the sidebar is now resized
automatically on each window resize (based on the percentage values).

Refactor the logic inside keys_display_bindings_bar() and remove the
need to place the "show next page" key binding at the right positions.
This used to be a pain to maintain, since we always had to move key
bindings around when introducing a new key. Fix this by passing the
actual key bindings in an array and using a separate parameter for the
"show next page" key binding (which is automatically inserted at the
right places from now on).

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 (
...);

Use one of the following functions where appropriate:
* puts() (whenever we print hard coded strings to stdout)
* fputs() (whenever we print hard coded strings to a stream)
* putchar() (whenever we print a single character to stdout)
* fputc() (whenever we print a single character to a stream)
* strncpy() (whenever we copy hard coded strings to a buffer)
This removes the overhead introduced by the format string parser and
reduces the number of false positive C-format strings spotted by
xgettext(1)'s heuristics.
