Refactor FBConfig lookup
Background: To bind a Xorg window content to a OpenGL FBConfig, which
has to match the color format the Xorg window is using.

Previously, compton just find a FBConfig that has the same depth. This
led to chjj/compton#477, which has been fixed by a ugly hack.

The commit refactor the lookup mechanism to take as much into
consideration as we reasonably can. Hopefully preventing similar
breakages in the future.

Also, some code sharing between the old and new glx backend.

Move session_t::pictfmts into x.c
As a global variable, since they shouldn't change during the period
compton is running. Also limit the scope of the variable to x.c.

Parse number locale-independently
Previously we were using glibc's strtod function to parse floating point
numbers. The problem is, strtod is locale dependent. Meaning 7,7 might
be parsed as two numbers (7 and 7) in one locale, and parsed as one
number (7 point 7) in another locale. This is undesirable.

We need to set the locale to a value we know to make number parsing
consistently. We could use setlocale(), but that is not thread-safe. We
can also use uselocale(), which is thread-safe, but doesn't cover strtod
(Yeah, some of the locale-aware functions only acknowledge the global
locale, not the thread local one).

So in frustration, I just wrote a simple floating point number parser
myself. This parser obviously doesn't cover all cases strtod covers, but
is good enough for our needs.

Improve config file search order
Previously the search order is:

~/.config/compton/compton.conf
/etc/xdg/compton/compton.conf
~/.config/compton.conf
/etc/xdg/compton.conf
...

Now the search order is:

~/.config/compton/compton.conf
~/.config/compton.conf
~/.compton.conf
/etc/xdg/compton/compton.conf
...

In other word, compton will now search all possible user config file
path first before searching for a system config file.

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
