4288866e55 glupload: relax the GLMemory uploader check for input caps features

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.

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.

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.

the 16bit data is uploaded as LUMINANCE_ALPHA, then expanded, composed

to [0~1]), low byte weight is 255/65535(similar)

efa22442a9 [838/906] gl: Use GL_TEXTURE_2D instead of GL_TEXTURE_RECTANGLE 
We create our textures (in Desktop GL) with GL_TEXTURE_RECTANGLE,
vaapi attempts to bind our texture to GL_TEXTURE_2D which throws a
GL_INVALID_OPERATION error and as thus, no video.

Also, by moving exclusively to GL_TEXTURE_2D and the npot extension
we also remove a difference between the Desktop GL and GLES2 code.
