d81eea5de1 glwindow: Hide navigation specific internal API and add API to asynchronously send navigation events 
Exposing the navigation thread's main context, GSourceFuncs and structs called
key_event and mouse_event is exposing a bit too much of the internals. Let's
just go with two functions to asynchronously send navigation events on the
window with the same API as the synchronous ones.

Also hide some internal functions and fields while we're at it and fix
a race condition with the startup condition variable.

420a175b4f glupload: Add dmabuf upload method. 
This upload method detect and optimize uploads of DMABuf memory. This is
done by creating and caching EGLImages wrapper around DMABuf. The
EGLImages are then binded to a texture which get converter using
standard shader.

Example pipeline:

GST_GL_PLATFORM=egl \
gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! \
               video/x-raw,format=NV12 ! glimagesink

1cd9786598 eglimagememory: Methods to create GstGLMemory from dmabufs 
Maps GstVideoFormats to suitable DRM fourccs which work with
glcolorconvert, using gst_gl_memory_alloc(). We require mostly
only 4 formats to be supported by the driver. We require DRM
equivalent to RGB16, RGBA, R8 and RG88. This way it's compatible with
DesktopGL, since GL_TEXTURE_2D is used and limit driver requirements.
With this we can virtually support all formats the glcolorconvert
supports.

6961945110 glmemory: add gst_gl_memory_allocator_get_default 
Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.

d8dacd50bf glbasememory: don't unconditionally add the alignment bytes to the size 
e.g when wrapping a data pointer we don't want to map/unmap off the end of
pointer with the alignment bytes.

Instead track that information separately as maxsize is used for mapping by
GstMemory and thus represents a size without any alignment padding bytes.

4c19b415bd gl: Allow using non-system mesa with both GL and GLES 
GCC automatically disable redundance warnings for system headers. As
soon as we start using a non-system installed mesa, we would start
having issues. The test for both wasn't setting any flags, so it would
work but then fail at runtime.

This is being fixed by disabling in the code (where needed only) that
GCC warning. The test is also fixed to avoid the false positive we had.

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.

d84d1708b7 glupload: Only offer custom allocator with caps features 
To use GLMemory and EGLImage allocators, one need to know the
libgstgl API. This is only expected if the associated caps features
have been negotiated. Generic element that otherwise receive those
allocators may fail, resulting in broken pieline. We don't want to
force all generic element to check if the allocator is a custom
allocator or a normal allocator (which implement the _alloc method).

614ea95690 gstglutils: fix shader compilation on Mountain Lion 
Make gst_gl_context_gen_shader/_compile_shader assume GST_GLSL_PROFILE_ES |
GST_GLSL_PROFILE_COMPATIBILITY as the profile. Without this, the shader compiler
doesn't inject the #version tag resulting in a compilation error on Mountain
Lion.

This is a workaround for old code using gst_gl_context_gen_shader. New code
should use the gst_glsl_stage_* API directly which allows the caller to
explicitly specify version/profile.

b429654a37 glbufferpool: add bufferpool options for the various texture targets 
This was chosen over relying solely on the caps as glupload needs to propose an

texture target when none has been configured.

be9ad5eeb2 glcontext: track sharedness with a cookie 
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.

When called from gst_gl_window_win32_close(), internal window
could not exist, and if it does it's going to be destroyed just
after that anyway. Also it causes window_proc() to be called
and crash because it gets a NULL context.

When called from gst_gl_window_win32_set_window_handle() we are
going to set another parent anyway, and it's probably better to
reparent directly instead of passing by a NULL parent which could
cause the internal window to popup briefly.

247697ce62 gl: win32: fix crash when finalizing GstGLContext 
gst_gl_context_finalize() is calling gst_gl_window_win32_quit()
which was posting a message. But then window_proc takes window's
context and get a NULL.

Now that we've got a GMainLoop we can do like other backends and
simply call g_main_loop_quit().

This also remove duplicated code to release the parent window and
potential crash there because parent_proc could be NULL if we never
created the internal window. That could happen for example if setting
state to READY then setting a window_handle, and go back to NULL state.

e1b077d6af glshader: attempt to detect the gles2 inside opengl3 case 
This is necessary to use gles2 shaders in a GL 3 core context on
OS X which fails without a proper #version being set on the shaders.

3d0bc93edc glshader: remove references to gl3 specific shaders 
We rely specifically on gles2 shaders being supported by the GL
implementation with GL3 core profile.

Use them as such.  They are also required for GL3 core profile support
with glDrawElements on OS X.

ba5130fe01 glmemory: properly detect (hopefully) the correct ext_rg/arb_rg variant 
GL_EXT_texture_rg is only valid for GLES2. GLES3 uses similar wording to
the GL_ARB_texture_rg which requires a sized internal format that the
GL_EXT_texture_rg does not require.

2ed71bee3b glcolorconvert: Improve passthrough check when no conversion is needed. 
Make the passthrough check contingent on only the fields we
can modify being unchanged, and pre-compute it when caps
change instead of checking on each buffer. Makes the passthrough
more lenient if consumers are lax about making input and output
caps complete.

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.
