Include gst/gl.h instead of specific headers to prevent such problems also in
the future.

The base class is useful for having multiple backing memory types other
than the default. e.g. IOSurface, EGLImage, dmabuf?
The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.
This also moves the format utility functions into their own file.
Heavily based on GstGLBaseBuffer that is a subclass of GstGLBaseMemory.
Provides GPU and CPU accessible GL buffer objects by GL handle or by
sysmem data pointer.
It handles the following
- GstAllocationParams -> gst_memory_init transformation
- Makes sure that map/unmap/create/destroy happen on the GL thread with
a GL context current.
- Holds a possible sysmem accessible data pointer with alignment.
- Holds the need upload/download transfer state
Rectangle textures don't use normalized coordinates so subsampling needs to be
factored in explicitly.
Fixes YUV => RGB conversion for rectangle textures.
To use GLMemory and EGLImage allocators, one need to know the
libgstgl API. This is only expected if the associated caps features
have been negotiated. Generic element that otherwise receive those
allocators may fail, resulting in broken pieline. We don't want to
force all generic element to check if the allocator is a custom
allocator or a normal allocator (which implement the _alloc method).

there could be other ways/requirements for synchronising two GPU command
streams (whether GL or platform specific).
e.g. glfencesync/eglwaitnative/cond/etc
given a NULL-terminated string, s.
s[i] = '\0';
i++;
does not guarentee that s[i] is NULL terminated and thus string operations
could read off the end of the array.

gst_gl_shader_detach_unlocked already removes the list entry so attempting to
use the element to iterate to the next stage could read invalid data.

Some drivers don't provide the compatibility definition and we need to provide
our own 'out vec4' variable to put the results of the fragment shader into.
