Remove redundant GST_VAAPI_TYPE_VIDEO_INFO, since it is a duplicate of
GST_TYPE_VIDEO_INFO created before gstreamer 1.6, where the boxed type
was created.

This patch adds the created allocator to the allocation query either
in decide_allocation() and propose_allocation() vmehtods.
With it, there's no need to set the modified allocator's size in the
pool configuration.

When calling gst_vaapi_video_memory_copy() the allocator of the memory
to copy should be allocated by the vaapi allocator.
This patch does this verification.
Instead of having a gst_vaapi_video_memory_free() that is only going to
be called by gst_vaapi_video_allocator_free(), let's just remove the first
and merged into the second.
There were duplicated code in gst_video_meta_unmap_vaapi_memory() and
gst_vaapi_video_memory_unmap() when unmapping.
This patch refactors both methods adding the common function
unmap_vaapi_memory(). This also ensures, if direct rendering is enabled, it
is correctly reset.
Additionally, only when mapping flag has the WRITE bit, it set the image as
current, which was done in gst_video_meta_map_vaapi_memory() but no in
gst_vaapi_video_memory_map().
In order to make this, the mapping flags were required, so instead of
overloading mem_unmap() virtual function, mem_unmap_full() is overloaded.

There were duplicated code in gst_video_meta_map_vaapi_memory() and
gst_vaapi_video_memory_map() when doing the READ and WRITE mapping.
This patch refactors both methods adding the common function
map_vaapi_memory().
Additionally, only when flag has the READ bit it calls
ensure_images_is_current(), which was done in
gst_video_meta_map_vaapi_memory() but no in
gst_vaapi_video_memory_map().

Previously the frame map counter increased independently if the map succeeded
or not. This leaded to critical messages and crashes if the frame was unable
to be mapped, but the counter increased.
This patch increases the map counter only if the map operation occurred.

If the allocator was configured to use direct upload or rendering, the
generated derived image created at mapping needs to be destroyed after
unmapping, because, in order to process the surface, it should not be marked
as "busy" by the driver.
The way to experiment with the direct rendering is through and internal
compiler pre-processor flag.
The current change set enables a way to specified at run-time, as a flag
passed to the allocator at instanciation time.
In order to clarify the use of flag as input parameter, it is renamed to
surface_alloc_flag, since it is used when creating a VA surface with certain
properties.

When calling gst_video_frame_map() with GST_MAP_WRITE flag, it doesn't call
ensure_image_is_current(), which means it doesn't guarentee VAImage is valid
in this case.

Add the method gst_allocator_get_vaapi_image_size() for the
GstVaapiVideoAllocator, which gets the size of the allocated images with the
current video info.
This method replaces the direct call to the allocator's image info when the
pool is configured.
Originally vaapivideobufferpool instantiates its own allocator regardless the
received configuration, and it relies in custom configuration options to
choose which kind of allocator instantiate.
This patch transfers the responsibility of the allocator instantiate to
vaapipluginbase and pass it to the vaapivideobufferpool through its
configuration.
* gst/vaapi/gstvaapipluginbase.c
+ set_dmabuf_allocator(): inserts a dmabuf allocator in the bufferpool
+ ensure_sinkpad_buffer_pool(): set a normal vaapi video allocator in
bufferpool configuration
+ gst_vaapi_plugin_base_propose_allocation(): call set_dmabuf_allocator() if
needed.
+ gst_vaapi_plugin_base_decide_allocation(): set a normal vaapi video
allocator in bufferpool configuration
* gst/vaapi/gstvaapivideobufferpool.c
+ gst_vaapi_video_buffer_pool_set_config(): instead of instantiate the
allocator, process the received one through its configuration.
* gst/vaapi/gstvaapivideobufferpool.h: removed
GST_BUFFER_POOL_OPTION_DMABUF_MEMORY since it is not used anymore.
* gst/vaapi/gstvaapivideomemory.c
+ gst_vaapi_is_dmabuf_allocator(): new helper function to identify a dmabuf
allocator with the vaapi qdata.

Instead of a dummy alloc() vmethod, the allocator instance set the flag
GST_ALLOCATOR_FLAG_CUSTOM_ALLOC, which is used by the framework to avoid call
gst_allocator_alloc() on the allocator.
As gst-indent generated ugly code in these cases, this patch changes the used
idiomatic into other one.
No functional changes were introduced.

If USE_NATIVE_FORMATS is defined we bail out before configuring the surface
info based on the derived image configuration.

First added the function gst_vaapi_video_format_get_best_native(), which
returns the best native format that matches a particular chroma type:
YUV 4:2:0 -> NV12, YUV 4:2:2 -> YUY2, YUV 4:0:0 -> Y800
RGB32 chroma and encoded format map to NV12 too.
That format is used to configure, initially, the surface's pool for the
allocator.

The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.
Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.
This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

The dmabuf allocator would close the DMABUF handle passed in the init
function gst_dmabuf_allocator_alloc(). So, we need to dup() it so that
to avoid a double close, ultimately in the underlying driver that owns
the DMABUF handle.
Allow v4l2src element to connected to vaapipostproc or vaapisink when
"io-mode" is set to "dmabuf-import". In practice, this is a more likely
operational mode with uvcvideo. Supporting v4lsrc with "io-mode" set
to "dmabuf" could work, but with more demanding driver or kernel reqs.
Note: with GStreamer 1.4, v4l2src (gst-plugins-good) needs to be built
with --without-libv4l2.

Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.
This is an API/ABI change, and SONAME version needs to be bumped.
In some occasions, a buffer pool is created for pre-initialization
purposes regardless of whether a valid image size is available or
not. However, during actual decode stage, the vaapidecode element
is expected to update the srcpad caps with the new dimensions, thus
also triggering a reset of the underlying bufferpool.
The ensure_surface() and ensure_image() functions shall only relate
to the underlying backing store. The actual current flags are to be
updated only through ensure_{surface,image}_is_current() or very other
particular cases in GstMemory hooks.
If the surface proxy is updated into the GstVaapiVideoMemory, then
it is assumed it is the most current representation of the current
video frame. Likewise, make a few more arrangements to have the
"current " flags set more consistently.
When interacting with SW elements, the buffers and underlying video
memory could be mapped as read/write. However, we need to use those
buffers again as plain VA surfaces, we have to make sure the VA image
is thus committed back to VA surface memory.
This fixes pipelines involving avdec_* and vaapi{postproc,sink}.
Hence vaapisink can display buffers decoded by gst-libav, or HW decoded
buffers can be further processed in-place, e.g. with a textoverlay.

Add GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC params flag that
can be used to disable early allocations of vaapi video metas on buffers,
thus delagating that to the bufferpool user.
