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

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

20836836b5 uninstalled.pc: add support for non libtool build systems
Currently the .la path is provided which requires to use libtool as
mentioned in the GStreamer manual section-helloworld-compilerun.html.
It is fine as long as the application is built using libtool.

So currently it is not possible to compile a GStreamer application
within gst-uninstalled with CMake or other build system different
than autotools.

This patch allows to do the following in gst-uninstalled env:
gcc test.c -o test $(pkg-config --cflags --libs gstreamer-1.0 \
    gstreamer-gl-1.0)
Previously it required to prepend libtool --mode=link
