This allow saving a copy with libav video decoders or decoders with
similar padding requirement.

ccf8f014f0 glupload: fallback to upload if contexts cannot share GL resources
Fixes pipelines of the form

    gleffects ! tee ! glimagesink

as tee does not pass on the allocation query.

6491af9ffc glupload: provide the output buffer that is rendered into
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.

57a54e9de4 glupload: always release the previous buffer
Fixes the case where _perform_with_buffer() is called without
intervening calls to _release_buffer() as is the case on start up
with glimagesink.

Also release the buffer when reseting the upload.

313dfbb500 gl/upload: switch the 'master' texture for YUY2, UYVY
From d4bcef3204 on, using a RGBA
texture to hold the data causes the glmemory to have half width
and a scaling of [2, 1].  Using a LA texture solves this problem
however cannot be attached to the framebuffer for copying into
a RGBA texture.  Which will be solved by moving to EXT_texture_rg.

030fc8b7d0 glupload: Ensure we still have a texture after upload_set_format()
gst_gl_upload_set_format() resets the upload, hence the texture.
So we need to ensure we have a texture after this call when
uploading.

c16ab9e66b gl/upload: set out_tex after reset, not before
Fix a regression introduced recently with the lazy init.
It was happening when calling gst_video_gl_texture_upload_meta_upload
from an aplication. So not using gst_gl_upload_perform_with_buffer.

94aa3ea228 glupload: Update GstVideoInfo after the buffer is mapped
gst_video_frame_map() will store an updated video info base
on the video meta. In order to have the right stride and offset

d7c5444447 gl: do not allocate the target texture of an EGLImage
The target texture of an EGLImage is the texture bind just
before calling glEGLImageTargetTexture2D.

As we currently only support a gl texture as the source of an EGLImage
the gl texture is actually already allocated when creating the eglimage.

I also see some cases where it fails to upload an eglimage when
glTexImage2D is called on the target.

30c6efc432 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.
