989200820d glmemory: add the texture type to allocate to parameters
Rather than assuming something.  e.g. zerocopy on iOS with GLES3 requires
the use of Luminance/Luminance Alpha formats and does not work with
Red/RG textures.

8ccf3dc589 glmemory: add wrapped data pointers to setup_buffer
Allows creating wrapped memories with GstGLAllocationParams.

The wrapped pointers will be set in the parameters before being passed
to the memory allocation function.

6961945110 glmemory: add gst_gl_memory_allocator_get_default
Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.

Fixes GL upload on iOS9 among other things.

650e5c4fe5 glmemory: implement GstGLBaseMemory::alloc
- Create GstGLVideoAllocationParams which is a GstGLAllocationParams subclass.
- Make it possible to allocate glmemory objects directly if no frills are
  needed.

2b7495bbc1 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.

b429654a37 glbufferpool: add bufferpool options for the various texture targets
This was chosen over relying solely on the caps as glupload needs to propose an
allocation and set the texture target based on the output caps.  Setting the
caps in the config is currently pointless as they are overwritten in a lot of
element's decide_allocation functions.

This provides a mechanism for the buffer pool to be configured for a certain
texture target when none has been configured.

e61d504556 glmemory: add support for rectangle textures
Add the various tokens/strings for the differnet texture types (2D, rect, oes)

Changes the GLmemory api to include the GstGLTextureTarget in all relevant
functions.

Update the relevant caps/templates for 2D only textures.

c3a47c910d glmemory: separate pbo transfer from texture transfers

4db0ef5789 glmemory: Use fallback for partial copy
When the memory is partial copy, the texture size and videoinfo no
longer make sense. As we cannot guess what the application wants, we

a4040f2ee9 glememory: only store and act on the map flags on first/last map/unmap
Anytime else, we have no idea how to match up map and unmaps.
We also don't know exactly how the calling code is using us.
Also fixes the case where we're trying to transfer while someone else
is accessing our data pointer or texture resulting in mismatched video
frames.

5f547c5600 gl: initial support for texture targets other than GL_TEXTURE_2D
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

9a55a3f98c glmemory: use pbo's for download

da3ae06cd1 glmemory: Handle upload/download flags from map
Problem was that if buffer was mapped READWRITE (state of buffers from
libav right now), mapping it READ/GL will not upload. This is because the
flag is only set when the buffer is unmapped. We can fix this by setting
the flags in map. This result in already mapped buffer that get mapped
to be read in GL will be uploaded. The problem is that if the write
mapper makes modification afterward, the modification will never get
uploaded.

Previously, we used the width to determine the amount of data to be

15d0c04933 gl/mem: allocate the memory per plane
This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.

Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).

Should not lose any features/video formats.
