de02a5c190 build: fix make dist with certain conditionals not met.
Fix generation of source tarballs when certain conditionals are not
met. e.g. always include all buildable codecparsers sources in the
distribution tarball, fix plug-in element sources set to include X11
and encoder bits.

de6a980065 vp8: allow compilation without the built-in libvpx.
The built-in libvpx serves multiple purposes, among which the most
important ones could be: track the most up-to-date, and optimized,
range decoder; allow for future hybrid implementations (non-VLD);
and have a completely independent range decoder implementation.

1ceef7d5b9 vp8: fix compilation with built-in libvpx.
Apply correct patch from fd.o #722760 to fix several issues: update the
license terms to LGPLv2.1+, fix dependencies to built-in libvpx and fix
make dist.

b36eade7f3 vp8: use range decoder from libvpx.
Add libvpx submodule that tracks the upstream version 1.3.0. This is
needed to build a libgstcodecparsers_vpx.so library with all symbols
placed into the GSTREAMER namespace.

4559f691a1 configure: always build the MPEG-4 parser.
Always build the MPEG-4 parser for now as there are also core fixes
included in the parser that cannot be tested for with API checks.

bd3aa01de5 build: fix compiling of local GstVideoDecoder and codecparsers.
Generated source files were missing a dependency on the complete set of
generated header files. e.g. gstvideodecoder.c requires gstvideoutils.h
to build and almost every codec parser source depends on parserutils.h.

d4a8e39656 libs: fix build of submodule wrappers.

newly generated headers when out-of-source builds are used.

9ab3ce2932 codecparsers: always build parserutils first.
Fix commit 18245b4 so that to link and build parserutils.[ch] first.
This is needed since that's the common dependency for actual codec
parsers (gstvc1parser.c for instance).

18245b484d codecparsers: always build the VC-1 parser library.
... this is useful to make sure pixel-aspect-ratio and framerate
information are correctly parsed since we have no means to detect
that at configure time.

9367c8ea58 mpeg2: fix PAR calculation from commit bd11bae.
Invoke gst_mpeg_video_finalise_mpeg2_sequence_header() to get the
correct PAR values. While doing so, require a newer version of the
bitstream parser library.

Note: it may be necessary to also parse the Sequence_Display_Extension()
header.

0b3d75f14b jpeg: fix default quantization tables.
Two elements in the luminance quantization table were wrong. So,
gst_jpeg_get_default_quantization_tables() now reconstructs tables
in zig-zag order from the standard ones (Tables K.1 and K.2).

f88323857d jpeg: compute default Huffman tables.
... instead of having them pre-calculated. This saves around 1.5 KB
of data in the DSO but requires gst_jpeg_get_default_huffman_tables()
to do more work. Though, the client application may have to call that
function at most once, only.

326a229636 codecparsers: jpeg: track valid quantization and Huffman tables.
Add valid flag to GstJpegQuantTable and GstJpegHuffmanTable so that
to determine whether a table actually changed since the last user
synchronization point. That way, this makes it possible for some
hardware accelerated decoding solution to upload only those tables
that changed.

segments or restart marker following it. The size and offset to
the associated data (ECS + RST segments) are append to a new
GstJpegScanOffsetSize structure.
