d5c3693791 gl: split glcolorconvert usage from glupload 
the separation allows the transfer operation to occur in a separate
thread/time which may increase performance in specific circumstances.

82a3a34475 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.

5b8d7a443e 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.

59088f5a90 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.

2da979831e 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.

2d0a791348 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.

d93cd25e2d 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.

803f2c3dc0 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
we should update that video info accordingly.

d4fe519c2e 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.
