gst_caps_intersect () may return an increased reference of one of the
input caps.
Fixes critical in the simple-launch-lines test:
Unexpected critical/warning: gst_caps_set_features: assertion 'IS_WRITABLE (caps)' failed

Generating those files is useful for users building the GStreamer stack
using meson and having to link it to another project which is still
using the autotools.
While doing so, fix some -uninstalled pc files which were using a
suspicious 'pcfiledir' which was never replaced or defined.

No-one's using/depending on it (it would have criticalled and not worked)
and it's causing more problems than it's solving. Store the GMainContext
in the public struct instead for subclasses to optionally use instead of
relying on the push/pop state to be correct.

middle textures in gleffects do not need to use GstGLMemoryPBO as they
aren't transfering data to/from the GPU. This will cost too much DMA
memory and cause performance issue. Change the allocator to use non-PBO
GstGLMemory.

glvideomixer does not support it currently and it needs special support
for handling this correctly, and is rather non-trivial to implement for
all formats.
If a sub class of GstGLContext does not create a group
then it currently crashes:
0 g_atomic_int_get (&share->refcount)
1 _context_share_group_is_shared (context->priv->sharegroup)
2 gst_gl_context_is_shared
3 _default_set_sync_gl

Calling g_main_context_push_thread and then g_main_context_invoke()
(used by gst_gl_window_send_message_async()) in the same thread will
cause the invoked function to run immediately instead of being delayed.
This had implications for the creation of the OpenGL context not waiting
until the main loop had completely started up and as a result would
sometimes deadlock in short create/destroy scenarios.

626bcccff9 removed some locks that
allowed the main loop quit to occur before the context was fully
created.
2776cef25d attempted to readd them but
missed the scop of the quit() call.
Also remove the use of g_thread_join() as that's not safe to use when
it's possible to lose the last reference from the GL thread.

It's been removed and thus compiling anything against GstGLMemoryEGL
would error with:

Create our own instead as the default framebuffer may require special
fiddling (like having a visible window) to correctly display/be renderable.
Fixes the remaining GL library tests on OS X
