e9327d4928 gl: Add support for Vivante EGL FB windowing system
This is very similar to how dispmanx on the Raspberry Pi works.

Based on a patch by Haihua Hu <b55597@freescale.com> from

once.

c83fd26c80 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.

aa6062945c gldisplay: make readding the same context a no-op
With e38af23044 returning the correct contexts,
gst_gl_display_add_context() was susceptible to causing infinte loops when
adding the same GstGLContext more than once.  Fix and add a test for
gst_gl_display_add_context().

Fixes glvideomixer gst-validate tests.

e38af23044 gldisplay: really retrieve glcontext for a specific thread
When requesting a glcontext (regardless of thread), the result was correct.
However, when requesting current glcontext on a specific thread, it could
come up with a glcontext active on another thread.

2b7495bbc1 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.

2704fdaa59 gl/wayland: add GstGLDisplayWayland
Simple implementation split from GstGLWindowWayland

Can now have multiple glimagesink elements all displaying output
linked via GL or otherwise (barring GL platform limitations).

The intel driver is racy and can crash setting up the two glimagesink contexts.

e.g.
videotestsrc ! tee name=t ! queue ! glupload ! glimagesinkelement
  t. ! queue ! gleffects_blur ! glimagesinkelement

videotestsrc ! glupload ! glfiltercube ! tee name=t ! queue ! glimagesinkelement
  t. ! queue ! gleffects_blur ! glimagesinkelement

1d16cd50a3 gl: add a scary note about initializing thread support for the winsys
We cannot do it as the winsys may crash if we initialize too late.

Example, GLX contexts with Intel drivers:
Intel requires the X Display to be the same in order to share GL
resources across GL contexts.  These GL contexts are generally
accessed from different threads.  Without winsys support it is
nearly impossible to guarentee that concurrent access will not
occur.  This concurrent access could result in crashes or abortion
by the winsys (xcb).

574b29f2c4 gl/wayland: create a dummy display instead of an EGLDisplay
Currently, GstGLWindowWaylandEGL holds the wayland display connection
If we create the EGLDisplay at the GstDisplay creation time, then
libEGL will internally open another connection to the wayland server.
These two display connections are unable to communicate resulting in
no window output/display and hangs inside libEGL.

Eventually we will move the wl_display from GstGLWindow to GstGLDisplay.

0ae3c984aa gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream

0d1d42b205 [890/906] x11: add display subclass
GstGLDisplayX11 holds the display connection and name.  Each thread requires
it's own X11 Display connection (initialised from name) due to the fact that
we do not want to call XInitThreads().  Doing so would result in segfaults
when integrating with GUI toolkits Gtk, Qt, etc.

The Display connection is for OpenGL platforms where a constant display is
required in order to share contexts (egl).  In the case of a wrapped context
(added later), we do not have GstGLWindow to retreive the display from so a
'master' connection is used instead.
