leftovers:
1) config file path. Has to implement compatibility functionalities before
we can change it.
2) links in man pages. Has to migrate the repo first.
3) _COMPTON_SHADOW, it has become a defacto standard, so we have to keep
supporting it.
4) dbus names, undecided whether we should/could change it.

Only render blur with transparency when window is fading in/out.
Otherwise, a window with a set opacity will always have a completely
blurred background.
Fixes#198

Currently compton handles window creation event by immediately query all
the information it needs and create a window struct with that
information. However, this is prone to race conditions.
In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.
This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.

Setting glx-swap-method to value other than "undefined" and "buffer-age"
could potentially cause rendering problems. So remove them, the meaning
of the remaining options can be more precisely captured by "use-damage",
so create a new option under that name.
--glx-swap-method is deprecated in favor of the new option --use-damage.

Choose the best vsync method for the user, instead of asking them to
frustratingly try every one of the options to see what works.
With this commit, the `vsync` option will take only a boolean value.

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.

If fork is requested, we fork as early as possible, way before anything
is initialized. This way, we don't need to do the gymnastics to make
OpenGL work properly across fork.

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.

* 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.

--dbe does not seem to have an effect on tearing, as noted in the old
manpage, and confirmed by my own testing.
So remove it, since it complicates the logic of painting.

IANAL, but I think I am allowed to add missing copyright notices for
someone else. And I did my best job using git history to figure out who
wrote which functions. So I hope everything is fine.
Bugs:
* There seems to be a noticeable frame loss when window
is being opened/closed. But the same problem also exists
in master/next, so this is not a regression.
* Using --sw-opti and --benchmark at the same time causing
compton to draw more frequently than permitted by the
arguments. That is because the sleep interval calculation
is flawed. Not really a regression either.
Verified still working:
* Usual painting
* Fade
* Benchmark mode
* --sw-opti (with or without benchmark mode)
* DBus
* Unredir delay

* Move code around
* Remove unneeded forward declaration
* Rename win->damaged to win->ever_damaged, to be less confusing
* Expose debug functions even when DEBUG is not enabled. Compiler
would remove the dead code for us anyway.
* Some code cleanup
