5aca58ce86 glmemorypbo: only create a pbo memory if the context actually supports it
e.g. GL <= 2.0 does not support pbo usage and GL 2.1 only supports pbo upload.

45d7796949 glmemorypbo: Comment out unused functions to fix compilation with clang
It's not clear if these are intentionally unused or the code should be
changed, but this fixes compilation for the time being at least.

1403a6871f 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.

8492c045a4 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

0468dc6663 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.

28dbe4fffc 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.

Fixes GL upload on iOS9 among other things.

f5dfc0ca35 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.

93215927a9 glbasememory: add a generic interface for allocating GL memories
This is made possible by a subclassable GstGLAllocationParams that holds
the allocation parameters

Every allocation would now go through gst_gl_base_memory_alloc with the
allocation parameters now being specified in a single struct to allow
extension by different allocators.

81cb10aa05 glbuffer: Don't pass allocation params
The imported memory has already been allocated, passing allocation
parameters with alignment confuses the memory which endup with a
size different from maxsize and lead to overrun when the memory
is being copied.

8f4ba29f97 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.

76a38dd66a 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.
