04e92acd3b glbasememory: take a pointer as the wrapped gpu handle
Allows passing arbitrary data to wrap the the specific memory implementation
which is required for some memory implementations.

f1737c8ad7 glbasememory: rollback map state when subclass map fails
Otherwise our state doesn't reflect reality.

910d990e4b glbasememory: Don't change maxsize at run-time
Maxsize is initialized once and should never change. Allocating data
should have no impact on the selected max size for this memory. This
causing memory map failure as the maxsize would become smaller then
size. This happened when using direct rendering in avviddec on GL that
does not support PBO transfer.

0cf1eaf71a glbasememory: Free the actual memory object when requested
Otherwise we are leaking ~400B on each GstMemory allocation.

Freeing in the base class matches the GObject semantics.

f5dfc0ca35 glbasememory: don't unconditionally add the alignment bytes to the size
e.g when wrapping a data pointer we don't want to map/unmap off the end of
pointer with the alignment bytes.

Instead track that information separately as maxsize is used for mapping by
GstMemory and thus represents a size without any alignment padding bytes.

09c8c23842 gl*memory*: reverse the parameter order of user_data and destroy notify
The convention is to have the destroy notify last after any user data

93215927a9 glbasememory: add a generic interface for allocating GL memories
This is made possible by a subclassable GstGLAllocationParams that holds
the allocation parameters

Every allocation would now go through gst_gl_base_memory_alloc with the
allocation parameters now being specified in a single struct to allow
extension by different allocators.

af7015602a gl: add a base memory object
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
