Buffer age is not a glx specific concept. xrender backend can have
buffer age too, if double buffering is used (required if we want to use
Present). So, make buffer age a generic concept in compton is required
for further backend improvements.
Moved buffer age based damage aggragation out of glx as well.

Previously, compton fails to stop draw_idle in some cases when sw_opti
is enabled.
sw_opti is a feature that limits the draw frequence to vblank frequence.
It adds a delay to drawing when the screen is updated more frequently
than the vblank frequence. However when the delay is not used (i.e. the
screen is updated infrequent enough), compton will start drawing the
frame directly without using the delay. And specically in this case,
compton will fail to stop the draw_idle, causing a callback to be called
once per loop of the mainloop, resulting in high CPU usage.
Fixes#92

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.

Move filling winopts with default values to after command line options have
been parsed, not after parsing the config file. This is more intuitive.

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

They should be useful for the refactored backends.
Renamed x_create_picture to x_create_picture_with_pictfmt.

When setting --shadow-exclude-reg from both the config file and the
command line, one of the strings is not freed.

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.

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.

So that the format arguments will only be evaluated if the log is
enabled by the log level. Allow us to add more expensive logs without
impact performance when they are not enabled.

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.

Also add a new config file path:
{$XDG_CONFIG_DIRS,$XDG_CONFIG_HOME}/compton/compton.conf
(For those not familiar with xdg: now compton will look for
~/.config/compton/compton.conf too)
