694d28eb78 Use tabs instead of spaces for indentation
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.

a363cb9b91 Fix braces in if-else statements
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.

e492ac6f95 Add hidden key handler window
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.

e16ac0a8a8 Do not display a mark when files are auto-saved
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.

e269f09438 Replace localtime() with localtime_r()
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.

4c4d4d3eb3 Use mvwaddstr() instead of mvwprintw()
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.

cfd8ede2b3 Switch to Linux kernel coding style
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.

6da787a5cc Declare several parameters/variables constant
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.
