This fixes --force-aliasing (and possibly other options) missing from the file.

If a malicious client pretends to be the E17 window manager, it is
possible to trigger an out of boundary heap write while receiving an
IPC message.
The length of the already received message is stored in an unsigned
short, which overflows after receiving 64 KB of data. It's comparably
small amount of data and therefore achievable for an attacker.
When len overflows, realloc() will either be called with a small value
and therefore chars will be appended out of bounds, or len + 1 will be
exactly 0, in which case realloc() behaves like free(). This could be
abused for a later double-free attack as it's even possible to overwrite
the free information -- but this depends on the malloc implementation.

The if statements are needed because we cannot pass a NULL pointer to
XFree.

The following adds the ability, when using `feh` as a background setter,
to use a specific Xinerama screen to render a provided image. Along with
the provided '--bg-*' option, the '--xinerama-index' argument will be
used to identify the index of the detected Xinerama screen to use.

The 'fehbg' variable can be allocated whether or not the user wishes to
generated a fehbg file. Ensure the variable is free'ed before we return.

Overloads the --geometry option for wallpaper setting
Currently only supports the two options that result in
black borders, --bg-max and --bg-center.
For both, if a geometry offset is specified (w/h is ignored),
the image will be offset the specified pixels from the screen edge
Left side for + numbers, right side for -.
+/-0 will align at the edge of the screen.

Previously feh would set a black background around wallpaper images,
with no option to change.
This commit extends the functionality offered by the --image-bg option,
which is available for regular image viewing, to centered and max'ed feh
backgrounds. Essentially, this means a white border can now be chosen
in addition to a black one.
