All API/ABI changes for S3D/MVC are added in 1.5, backporting
them to older verison is not recommended.

89e41fc8e3 build: use git.mk
This patch handles dinamically the gitignore files with git.mk[1].

Removed the automake variable MAINTAINERCLANFILES in most of the
Makefile.am files since now it is handled by the top one.

ae95a72dd1 h264parse: update patches with upstream
These patches didn't applied cleanly, breaking the `make distcleancheck`
target. Re-sync'ed the patches against the current git's submodule.

8c7bc7dff8 plugins: Add h265 videoparser element "vaapiparse_h265"
This is a mirror of h265parse element in upstream gst-plugins-bad.
There could be additional patches but all should go to upstream.
This is for making development faster.

Note: vaapiparse_h265 will get build only for GStreamer version >= 1.4

1650471da3 h264parse: fix detection of access unit boundaries for MVC.
The gst_h264_parse_collect_nal() function is a misnomer. In reality,
this function is used to determine access unit boundaries, i.e. that
is the key function for alignment=au output format generation.

92c7d9e6a5 h264parse: fix collection of access units to preserve config headers.
Always use a GstAdapter when collecting access units (alignment="au")
in either byte-stream or avcC format. This is required to properly
preserve config headers like SPS and PPS when invalid or broken NAL
units are subsequently parsed.

More precisely, this fixes scenario like:
<SPS> <PPS> <invalid-NAL> <slice>

where we used to reset the output frame buffer when an invalid or
broken NAL is parsed, i.e. SPS and PPS NAL units were lost, thus
preventing the next slice unit to be decoded, should this also
represent any valid data.

2905209d9b h264parse: improve conditions for skipping NAL units.
Carefully track cases when skipping broken or invalid NAL units is
necessary. In particular, always allow NAL units to be processed
and let that gst_h264_parse_process_nal() function decide on whether
the current NAL needs to be dropped or not.

This fixes parsing of streams with SEI NAL buffering_period() message
inserted between SPS and PPS, or SPS-Ext NAL following a traditional
SPS NAL unit, among other cases too.

Practical examples from the H.264 AVC conformance suite include
alphaconformanceG, CVSE2_Sony_B, CVSE3_Sony_H, CVSEFDFT3_Sony_E
when parsing in stream-format=byte-stream,alignment=au mode.

6d6caf17c9 h264parse: introduce new state tracking variables.
Improve parser state tracking by introducing new flags reflecting
it: "got-sps", "got-pps" and "got-slice". This is an addition for
robustness purposes.

Older have_sps and have_pps variables are kept because they have
a different meaning. i.e. they are used for deciding on when to
submit updated caps or not, and rather mean "have new SPS/PPS to
be submitted?"

c767be53d6 h264parse: default to byte-stream/nalu format (Annex B).
Always default to stream-format=byte-stream,alignment=nalu if avcC
format was not detected. This is the natural stream format specified
in the standard (Annex.B): a series of NAL units prefixed with the
usual start code.

8b473972e0 h264parse: fix and optimize NAL collection function.
Use gst_h264_parser_identify_nalu_unchecked() to identify the next
NAL unit. We don't want to parse the full NAL unit, but only the
header bytes and possibly the first RBSP byte for identifying the
first_mb_in_slice syntax element.

Also fix check for failure when returning from that function. The
only success condition for that is GST_H264_PARSER_OK, so use it.

3af6b0b8a0 plugins: add built-in video parsers as "vaapiparse" element.
The built-in video parsers elements are built into a single DSO named
libgstvaapi_parse.so. The various video parsers could be accessed as
vaapiparse_CODEC.

For now, this only includes a modified version of h264parse so that to
support H.264 MVC encoded streams.
