Wait for PresentCompleteNotify
Don't use idle fence. There is no reliable & portable way to obtain a
fence Present will like. Intel driver wants a DRI3 fence, NVIDIA driver
doesn't support DRI3, and wants a XSync fence (I am not even sure, since
Present doesn't really work with the NVIDIA driver. And using the fence
on NVIDIA driver causes compton to use 100% CPU).

Just don't bother.

Don't stop fading for window size change
Window size change cause window resource to be released and re-acquired,
so it cannot work on unmapped windows.

Previously we make sure of that by skipping fading and change if the
window is mapped. Now we just make sure that functino is never called
with an unmapped window.

Make sure map_win initialize win::win_data
Previously it is initialized by win_update_bounding_shape, so
configure_win is called when win_data == NULL and state ==
WSTATE_MAPPING, which is an invalid state for a `win` to be in.

Now map_win explicitly calls backend->prepare_win. This is not very
efficient since win_update_bounding_shape will reinit it.

Don't call map_win() in add_win()
Only case where you want to map window in add_win() is during compton
startup, when compton is registering existing windows. Otherwise,
add_win() is always called for newly created windows, so there will
always be a MapNotify coming up for that window. If we map newly created
windows in add_win(), we will try to map it a second time when the MapNotify
arrives.

So, just don't call map_win() from add_win(). For compton startup, we
explicitly call map_win() after calling add_win() in session_init.

Fix a use-after-free
paint_preprocess takes head of the window list as an argument. The
actual head of the window list might be freed and deleted during processing
of fade, but paint_preprocess will keep using the old head of the list,
thus uses freed memory.

Solution is just don't pass the head as an argument. paint_preprocess
will use session_t::list directly.

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.

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.

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

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

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.

Use glDrawBuffer instead of glDrawBuffers in glx_blur_dst
glDrawBuffers doesn't take GL_BACK, which is what we are passing. And we
are using only one buffer argument anyway, no need to use glDrawBuffers.
