c3a47c910d glmemory: separate pbo transfer from texture transfers
When supported, the potentially longer pbo upload/download can be
initiated before the texture upload/download, potentially increasing
throughput.

1de2e2bc39 glupload: Make upload method static caps non-const.
Retrieving a GstStaticCaps does a one time internal
initialisation and caches it - they can't be stored as
const structures.

d925e7fd19 glupload: move meta-data copy into gst-gl library
In some upload implementations the out buffer has more than one references,
turning the buffer not writable, so it won't be possible to modify its
meta-data.

This patch moves the meta-data copy before increasing the reference of the out
buffer.

75e875b022 glupload: Set freed method implementation to NULL
When trying to render buffers with meta:GLTextureUpload the glimagesink crashes
with a segmentation fault.

This patch workarounds this crash setting to NULL the method implementation

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.

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.

gst_gl_upload_set_format() resets the upload, hence the texture.
