Slightly clean up header inclusion with the help of clang's module system.
It's better for files to include the things you need directly.

glStringMarker is usually only available when running under some
kind of GL debugger, and can be used to insert strings into the
GL command string. Writing logs using it can be useful, since it
lets us correspond GL calls with what happens in compton.

This commit introduced a new, modular backend interface. The interface
is not very good, since I don't think I fully understand all the
requirements writing a backend have. But this is a good first step.
This commit also includes an initial xrender backend written using the
new interface, and some opengl backend related helper functions, which
are taken from the old opengl backend.
However, there is not integration with the core compton yet. compton
will still use the old backend code. This commit is here so we can get
the automated build test.
What is implemented in the new xrender backend:
* Windows with transparency
* Shadow
* Opacity
* Wallpaper (getting the root pixmap)
* Blur
Known problem with the xrender backend:
* It is slower
Things that still need to be figured out:
* What is the better way to add vsync to the new backends

Also add a new option "log-file" to config file and command line, it
doesn the same thing as --logpath.
--logpath was never documented, and "log-file" is more consistent with
the naming of options.

* Pass a options_t, not session_t
* Slightly improve error handling when setting vsync method via dbus
The goal here is to limit the scope of what a given function can access.
And session_t contains basically everything, so don't pass it around.

* -d: because the standard way is to use $DISPLAY
* no-name-pixmap: undocumented debugging option
* -S: debugging option, not very useful

* Moved dbus prototypes from common.h to dbus.h
* Removed private function prototypes from dbus.h
* Removed private macros from dbus.h
* Hide dbus types from common.h

And improve some of the log messages. Like, when compton exits because
of unsupported options, explain which options are causing compton to
quit.
Convert some debugging messages that are guarded behind ifdef's to log_trace,
so user don't need to re-compile to enabled them.

Moved:
* Blur kernel related functions to kernel.c
* Vsync related functions to vsync.c
* paint related functions to render.c
This will make the `split-backend` branch easier to rebase.

* string functions mstr*() are moved to string_utils.c
* allocation wrappers are moved to utils.h
* printf_* functions are moved to log.h

Both methods are redundant. Prefer Mesa's own extension when available,
fall back to the old SGI extension otherwise (NVIDIA drivers for the
most part).
The old shadow kernel formula is not "wrong" per se, as the only judge
is if it looks good. However, the formula used is not really gaussian.
Also, the kernel size calculation doesn't really make sense to me.
This commit change the kernel formula to actually use a gaussian
distribution. As far as I can tell, there is no perceivable difference.
Except now the effective shadow radius is smaller for the same config.
Also, made that part of code a bit more mordern.

libglvnd seems to return a pointer to a function that does NOTHING
for things the backing driver doesn't support.
So we check if the extension is actually advertised before using it.

I just realized wintype option shadow and fade never worked. If you set
the global shadow option to true, wintype shadow option will have no effect.
Now the wintype options will properly override the global ones.
Also remove deprecated options from compton.sample.conf.

Calling ev_break() in a signal handler doesn't work. Instead, we setup a
libev ev_signal handler for this.
