Make buffer age not glx specific

Make buffer age not glx specific
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.

Make sure draw_idle is stopped in all cases
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

Enable the glStringMarker logger when available
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.

More info about the extension can be found here:

First step of split backend into modules
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

* Pass a options_t, not session_t
* Slightly improve error handling when setting vsync method via dbus

Make the shadow actually gaussian
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.
