fill_win only sets the pending geometry (aka the shadow geometry) of the
window, we have to wait for it to propagate to the real geometry before
we can update the screen.

Since commit 95a64acf5a, fill_win doesn't
set the window geometry anymore, so we can't use it in
handle_new_windows.
However, we don't need to add damage in handle_new_windows anyway,
damage will be added later when the MAPPED flag is handled.

Consider these 2 cases:
* A window is mapped while fading out
* A window is mapped and damaged while fading out
From the perspective of map_win_start, these 2 cases look the same. The
window will has ever_damage = true in both cases. However, map_win_start
has to distinguish between these 2 cases, because at the end of
map_win_start, window in the first case cannot have ever_damage = true,
while window in the second case should have ever_damage = true.
Currently, map_win_start always clears ever_damage in both cases
(indirectly through win_skip_fading), which causes windows in the second
case to not be rendered when they should be.
This commit move clearing of ever_damage from unmap_win_finish to
unmap_win_start, so when map_win_start sees ever_damage = true, it's
always to second case. And to make sure windows which are fading out are
still rendered, we relax the ever_damage check in paint_preprocess to
also accept windows that are fading out. (see code comment for
explanation why this is fine)

When a window is moved during fade-out, configure_win won't add the old
window extent to damage (because it's unmapping), but the new window
extent will be added to damage when the window is rendered. And the
window will be rendered in its new location. Thus the damage for the old
window extent is missing.
We could fix this by adding damage in configure_win for unmapping window
too. But in general we don't want to move a window while it's fading
out. So we shadow the window geometry. The shadow geometry is updated in
configure_win, and the update will only propagate to real geometry in
win_process_update_flags.
This also fix the case where a window is unmapped, moved, then mapped
all in the same render cycle. map_win_start is supposed to add the old
window extent to damage in that case, but the old window extent is
already overwritten when we reach map_win_start. The shadow geometry
fixes that.

Set WIN_FLAGS_MAPPED instead, it will be handled later. Previously, we
call map_win_start because we need the geometry of the window, which is
updated in map_win_start. Now, we get the geometry in fill_win, so
map_win_start is not needed anymore.
Eliminate a case where destroy_backend could see IMAGES_STALE flags set
on windows.

Make unmapped window events work mostly like a mapped window, except
flags set on unmapped windows aren't processed until the window is
mapped.
Hopefully this unifies some of the code paths and reduce corner cases.

Per POSIX, "The c argument is an int, the value of which the application
shall ensure is a character representable as an unsigned char or equal
to the value of the macro EOF. If the argument has any other value, the
behavior is undefined."

When the screen is unredirected, no window have a shadow image. So the
assertions in win_set_shadow don't hold. But in that case, we don't want
to add damages anyway. So we put them behind a check of whether the screen
is redirected.

- Fix non-critical memory-leak in `picom.c` and `options.c` where we
don't free all allocated memory before dieing.
- Explicitly allocate new branch in `c2.c` to silence false-positive
memory-leak.
Downstream code expect wid_get_text_prop to return at least 1 string.
However wid_get_text_prop would return 0 strings when the property is
set to an empty string.

Clear both STALE flags (`IMAGES_STALE = PIXMAP_STALE | SHADOW_STALE`)
when destroying windows (see f493447b33).
Clearing `SHADOW_STALE` as well should eliminate the recreation of a shadow
image for a window currently being destroyed which will cause the
rendering to fail because we can't properly update the flags anymore.
Should fix: #394
Of course, we still use GLX, so we can't completely remove Xlib yet. But
this removes all Xlib uses outside of the backends.
This drops support for COMPOUND_TEXT Xorg strings, so people how wants
multilingual support has to use UTF8, which should be fine since most of
the applications support that.

If a window receives multiple configure notifies in between 2 frames, we
add all the in between positions into damage, when we really just need
the starting and the end position.

So we don't need to call c2_match every frame something is fading. Also
saves us from some out-of-critical-section X server queries.

Previously, when some explicitly checked property (e.g.
_NET_WM_WINDOW_OPACITY) changed, it won't trigger a
win_on_factor_change, and the rules will not be re-evaluated. Because
that property stale flag will be cleared after we explicitly check the
property, so it won't be detected as a tracked property change.
Here, we instead set WIN_FLAGS_FACTOR_CHANGED directly when a tracked
property changed.
