Need to add gio-unix-2.0 dep to pipelines/tcp test otherwise it
won't find the gio/gunixfdmessage.h header which is not in the
same dir as the other gio headers. This issue was masked before
because we didn't include config.h so HAVE_GIO_UNIX_2_0
wasn't defined.
In many cases the unistd.h includes weren't actually needed.
Don't build tests that need it on windows with MSVC
(multifdsink, multisocketsink, pipelines/tcp).
Preparation for making tests work on Windows with MSVC.
Some GL platforms (EGL, WGL) require deactivating the OpenGL context in
one thread before it can be used in another thread which this test
currently violates and would e.g. result in EGL_BAD_ACCESS errors from
gst_gl_context_activate().
Fix by moving the object creation into the GL thread instead and not
requiring additional gst_gl_context_activate() calls.

If timestamp goes forwards more than allowed, we consider that the
timestamp belongs to the previous counting, so the extended timestamp
is unwrapped.

Tests and documentation will follow separately.
The mixer elements in the opengl plugin need to stay
in -bad for now since they use GstVideoAggregator.

Except for gst/gl/gstglfuncs.h
It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.
For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.
For example with this patch, if an app includes the headers
gst/gl/egl/gstglcontext_egl.h
gst/gl/egl/gstgldisplay_egl.h
gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.
Also added a test: cd tests/check && make libs/gstglheaders.check

Create our own instead as the default framebuffer may require special
fiddling (like having a visible window) to correctly display/be renderable.
Fixes the remaining GL library tests on OS X
The spec allows the core/compatibility profiles to be used
with #version 150.
Also tighten up the tests to check for default profiles being chosen
correctly.
The tests were broken since 91fea30, which changed glupload to return
GST_GL_UPLOAD_RECONFIGURE if the texture target in the input buffers doesn't
match the texture-target configured in the output caps.
This commit fixes that and adds more checks for the new behaviour.
Facilities are given to create fbo's and attach GL memory (renderbuffers
or textures). It also keeps track of the renderable size for use with
effective use with glViewport().
Rather than assuming something. e.g. zerocopy on iOS with GLES3 requires
the use of Luminance/Luminance Alpha formats and does not work with
Red/RG textures.
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.
Some operations are unnecessary when running with only a single GL
context.
e.g. glFlush when setting a fence object as the flush happens on wait.
API: gst_gl_context_is_shared
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.
