Let old/new backends co-exist
Now both the old and the new backends are compiled in, the user can
choose which one to use with a command line switch.

Cut fading short if we decide to unredirect the screen
Previously if we unredirect the screen while a fading is in progress, we
will "resume" the fading when we redirect the screen again.

This is usually fine unless the window being faded out is destroyed. we
still tries to fade it out, but since we don't have the pixmap of the
window anymore (freed by unredirect), we will generate lots of errors
until the window is completely "faded out".

Also this change makes it easy to reason about things. Now we know when
the screen is unredirected, all the windows can either be in MAPPED or
UNMAPPED state, nothing else.

Destroy Input Only window properly
Destruction of Input Only windows is erroneously ignored by commit
cea010a, causing future window with the same window id as the destroyed
Input Only window to be treated by an Input Only window even when they
are not. The end result is that some windows don't show up.

Also improved the comments in win.c.

Fixes #119

Remove win::*_last
A side effect of this is that some window properties are allowed to
change during fade-in/out. (e.g. window background can become blurred
during window fade out if window properties changed so blur is requirired).
But it is unclear what is the expected behaviour in this case anyway, so we
choose the one that is simpler to implement.

Window state tracking refactor
Window state tracking is basically the back bond of window fading. We
add a new enum field to the win struct to track the state of the window,
instead of using a set of boolean variables. We also remove the fading
callbacks, since it is only used for fading, so the potential of code
reuse is lost. And it makes the code slightly harder to understand.

Also fixed a problem that --no-fading-openclose is not behaving as
advertised (from my observation, enabling this flag disables fading
entirely, instead of just diabling it for open/close).

Also uses double for opacity everywhere internally. Use opacity_t only
when setting X opacity prop.

Handle SIGINT using libev's ev_signal handler, instead of using
sigaction().

Fixes #64. But compton might miss signals when it's not in the main loop
(e.g. when compton is reset), and thus not exit "clearly". It should
cause any real problem though, so we don't care.

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.

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
