1153684a94 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.

1da12235c3 gl/upload/meta: remove unneeded texture deletion
The textures are managed by the GstGLMemory inside the output buffer.  Freeing
them prematurely may result in a use-after-free.

5efc2e8705 gl/egl: replace gsteglimagememory with an EGLImage wrapper
That can be passed to GstGLMemoryEGL.

This also ports the dmabuf uploader to GstEGLImage and GstGLMemoryEGL.

ecfe5b0801 gl: implement GstGLMemoryEGL
Because current GstEGLImageMemory does not inherit GstGLMemory, GLUpload
allocates additional GLMemory and upload the decoded contents from the decoder
which uses EGLImage (e.g. gst-omx in RPi).

This work adds GstGLMemoryEGL to avoid this overhead. Decoders allocate
GstGLMemoryEGL and decode its contents to the EGLImage of GstGLMemoryEGL.  And
GLUpload uses this memory without allocation of additional textures and blit
operations.

[Matthew Waters]: gst-indent the sources and fix a critical retreiving the egl
display from the memory.

2753b4243e glmemory: add wrapped data pointers to setup_buffer
Allows creating wrapped memories with GstGLAllocationParams.

3ee2183038 glupload: keep the parent buffer around when converting EGLImage to 2D textures
e.g. receiving and releasing a buffer from OMX too early will potentially
cause textures to be overwritten while/before they are displayed.

356494d967 glupload: deal with the ANY caps feature correctly
When transforming, xplode it out into the necessary caps features both
with and without the passthough features.

Fixes negotiation in the following class of pipelines:

gl ! textoverlay ! glupload ! glimagesinkelement

86110c4765 glupload: always add texture-target field to GL caps
1. Various elements/base classes only perform a subset check on accept-caps
2. Some GL elements have texture-target in their pad template
3. When checking subsets, only the caps to check are allowed to contain extra
   fields.  If the 'template' caps have extra fields, the subset fails.
Thus without texture-target on the caps, various accept-caps implementations
were failing.

Also, add some convenience functions for setting and retrieving
texture targets to/from GValue.

8492c045a4 glupload: Add dmabuf upload method.
This upload method detect and optimize uploads of DMABuf memory. This is
done by creating and caching EGLImages wrapper around DMABuf. The
EGLImages are then binded to a texture which get converter using
standard shader.

Example pipeline:

GST_GL_PLATFORM=egl \
gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! \
               video/x-raw,format=NV12 ! glimagesink

28dbe4fffc 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.

76a38dd66a 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.

21df596b8b glupload: Only offer custom allocator with caps features
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).

260104e485 glupload: Remove debug output from gst_gl_upload_transform_caps()
We can't know if the GstGLUpload type is initialized at this point already,
and thus our debug category might not be initialized yet... and cause an
assertion here.

As we don't print debug output for any of the other transform functions, let's
defer this problem for now.

55dbb25dcc glupload: move meta-data copy into gst-gl library

turning the buffer not writable, so it won't be possible to modify its
