b1a60af720 eglimage: perform eglCreateImage in the gl thread
while calling eglCreateImage without a GL context current in the executing
thread works on the RPi, some other implementations will return errors.

Marshall the eglCreateImage to the GL thread to appease these implementations.

cbf3a986ca glviewconvert: support outputting to multiple draw buffers on GLES3

mangling.

85cddc0891 glcolorconvert: implement multiple render targets for GLES3
There are numerous slight differences required between Desktop GL and GLES3 for
multiple render targets.

1. gl_FragData doesn't exist at all and one is required to use
   'layout (location = ?) out ...' instead.
2. gl_FragColor doesn't exist, same as 1
3. texture2D() has been deprecated

Fortunately most of these have been taken care of with GL3 and the shader
mangling already exists so just expand the conditions they are used in.  The
gl_FragData issue requires a new mangle pass though.  We also use this new
pass on desktop GL for consistency.

0c2890cd34 glmemory: add checking the read implementation format/type on gles2 platforms
By default, reading GL_RED or GL_RG us unsupported by glReadPixels unless
exposed through GL_COLOR_READ_IMPLEMENTATION_FORMAT/TYPE.  This allows
downloading multiple-planar video frames where possible.

ccbf43987f glshader: add glBindFragDataLocation
There are some cases where it's needed for binding in/out variables in shaders.
e.g. glsl 150 (gl 3.2) doesn't support the 'layout (location = ?)' specifiers in
the shader source so we have to bind them ourselves.

d5cc277601 glfilter: only allow the same src/sink caps when we are in passthrough mode
If we are given caps with extra features (like the overlay composition
features), we can only deal with that when we are in passthrough mode.

Previously we were bailing entirely and not allowing passthrough filter elements
with things like textoverlay.

Fixes the following pipeline (assuming glfilter supports passthrough):
gl ! textoverlay ! glfilter ! ... ! glimagesinkelement

eb1a9bb9b0 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.

90889bc73f libgstgl: cocoa, eagl: don't marshal GL calls to the context thread
Execute GL calls without marshalling them to the context thread. In the cocoa
and eagl backends calling gst_gl_context_activate is cheap and therefore calling
it on the current thread and serializing GL calls with a per-context lock is
more efficient (faster and has less overhead) than marshalling everything to the
context thread.

This optimization cuts a large overhead in g_poll (continuously waking up the
context thread) and in g_mutex_*/g_cond_* (waiting for results from the context
thread).

6d343abec8 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.

910d990e4b glbasememory: Don't change maxsize at run-time
Maxsize is initialized once and should never change. Allocating data
should have no impact on the selected max size for this memory. This
causing memory map failure as the maxsize would become smaller then
size. This happened when using direct rendering in avviddec on GL that
does not support PBO transfer.

5f87cc0b65 glcontext: add a method to add a context to another share group
Intended for use with wrapped contexts that are created shared with gst's
gl contexts in order to manage the internal sharegroup state correctly.

e.g. with caopengllayer (which is used in glimagesink and caopengllayersink
on OS X), we create a CGL context from the gst context and the sharing state
was not being correctly set on either GL context and gst_gl_context_is_shared()
was always returning FALSE.

With 11fb4fff80 only flushing with multiple
shared contexts, the required flush was not occuring causing screen
corruption or stuttering.

Note: this didn't affect GST_GL_API=opengl pipelines
