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.

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)

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).
This should give us sane item size, i.e. the item has the same number of
bits their format says they have.

Foolish of me to assume the returned window property items have the same
number of bits their format says they have.
Apparently, format = 32 means the return items are 64 bits long (on
64-bit machines).

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.

Make sure the wintype options are properly initialized even when there
is no config file specified/supported.

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.

When using DRI2, Mesa uses XESetWireToEvent to hook into Xlib's event
handling loop, so it can get notified when certain DRI2 event happens,
which is crucial to the normal functioning of GLX.
When xcb is owning the event queue (meaning libxcb is doing all the
event handling), those functions registered by Mesa will never be
called, thus GLX will malfunction, leading to screen flickers or visual
artifacts.
This commit uses a hack from Qt to manually call those functions in
compton.
