glmemorypbo: don't double read pixels
...
The optimistic download_transfer was not setting the required flag to not
perform glReadPixels on subsequent map (READ). resulting in glReadPixels
happening twice.

glmemorypbo: fix wrapping data on GL 2.1
...
GL 2.1 only supports pbo upload.
The wrapped data pointer was only being set on the pbo memory and on the
glmemory so when a download was requested (in GL 2.1), glmemory was
allocating a new data pointer and thus not returning the wrapped data.

glmemorypbo: only create a pbo memory if the context actually supports it
...
e.g. GL <= 2.0 does not support pbo usage and GL 2.1 only supports pbo upload.

glmemorypbo: Comment out unused functions to fix compilation with clang
...
It's not clear if these are intentionally unused or the code should be
changed, but this fixes compilation for the time being at least.

glmemory: base classify and add the pbo memory on top
...
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.
