Basically we won't call xcb_damage_subtract if show_all_xerrors is set,
which is very bad.
Fixes that, and also make sure the damage subtract request is flushed in
all branches.

Instead of change window attributes back and forth, calculate the evmask
and set it just once. And also make sure the request is flushed.

There is actually no specification what symbols are exported from a
libGL implementation. The (extremely outdated) OpenGL ABI specification
says only GL 1.2 functions are guaranteed. Don't know how relevant that
is now, but different libGL implementations do export different set of
symbols. On Linux we are most likely to be linked with libglvnd, which
has everything we need. But on other platforms this is not necessarily
the case, for example on OpenBSD we are missing glGetQueryObjectui64v.
Use libepoxy so we can outsource this problem and never worry about it
ever again. Plus it also saves us from calling GetProcAddress ourselves.
Changes other than trivial build fixes I have to make:
1. Can't use eglCreatePlatformWindowSurface/eglGetPlatformDisplay.
libepoxy checks for EGL 1.5 when resolving these functions. But
without a current context, libepoxy assumes we only have EGL 1.4.
This creates a chicken and egg problem - we need a display to call
eglGetPlatformDisplay. We have to use the *EXT version instead.

I think I was trying to avoid introducing pthread as a dependency, but
now we are using pthread for SGI_video_sync thread anyway. Let's remove
the ifdefs.

OpenBSD don't have support for sched_getparam(), sched_setparam(), or
sched_setscheduler() functions (yet). In this case, we need use
pthead-equivalents for real-time sched for picom. Theses changes add
this support.

Image decouple should keep all the image properies from the source
image, so shader must be copied. And there are also some internal
properties what should be inherited but wasn't.
In particular this prevents images from losing their shaders when
alpha is applied.
Fixes#1174
fix the same issue in the legacy backends, see the previous commit for
details. this commit also removes the x_validate_pixmap function because
it was used only in the get_root_tile function and the fix pretty much
implies and embeds it.
if the root background pixmap's depth doesn't match the root window's
depth, find a suitable visual for the root background pixmap's depth and
use it instead of the root window's visual
On a second thought, the `corner-radius-rules` is a user noticeable
behavioral change, it should be more prominent.
