    Chromium patch and README updates

    Updated date/hash of merge in README.chromium
    Updated Chromium patches:
      The merge from upstream tentatively took the rewritten upstream
        version of configure's mips64 logic. Previously, a downstream patch
        to configure was necessary to prevent mips arch selection conflict.
      The merge from upstream also removed our custom downstream declaration
        of matroska_read_close from lavf/matroskadec.c now that upstream
        includes it later in that file.
      In the merge from upstream, previously 8b946dec7 removed lavf/mov.c
        mov_seek_stream()'s |ret| local, but more recent dd34e89f needed it.
        Resolved by declaring |ret|.
      The merge commit included additional removal of extra const from
        static EbmlSyntax arrays in lavf/matroskadec.c
      riffdec.c VS2015 update 1 codegen workaround is now in ffmpeg
        upstream.
      Removed from README previous cherry-picks from upstream, confirmed in
        git history.
      generate_gn.py should now autorename to escape conflicts like
        lavc/videodsp.S and lavc/aarch64/videodsp.S which otherwise both
        result in videodsp.o in the same folder. Removed the temporary
        downstream rename of lavc/aarch64/videodsp.S to videodsp_aarch64.S
    Removed more UNCHECKED_BITSTREAM_READER defines from lavc/*

    Enable mac build_ffmpeg of lavf/wavdec.c

    Mac searches more extensively for symbols when building dynamic
    libaries.  Since last ffmpeg roll, wavdec.c now conditionally calls a
    method ff_spdif_probe, which is not included in build
    (CONFIG_SPDIF_DEMUXER is disabled), and build_ffmpeg on mac thus fails.

    This change uses a downstream #if to completely remove the call to
    ff_spdif_probe in wavdec.c

Affects:
    libavformat/wavdec.c

    Enable windows Chrom* build including lavf/wavdec.c

    Expands the downstream #if's to exclude more code blocks including
    symbols not in our builds, gated by each of CONFIG_SPDIF_DEMUXER and
    CONFIG_W64_DEMUXER. At least the windows toolchain otherwise would fail
    linking Chrom* pieces due to resolved symbols without this change.

    Fix dictionary leak in mp3dec

    Upstream changes in mp3dec.c introduced a leak. s->metadata is
    (correctly) assumed to be NULL when entering mp3_read_header,
    but Chromium uses a custom dictionary entry to skip id3v1 tag
    parsing, which requires an additional call to av_dict_free.

    Disable unused ogg codec parsers; they have bugs we don't care about.

    Ogg has parsers for a bunch of codecs we don't care about. Long ago
    we also disabled these, but we re-enabled them because it didn't
    matter at the time. We would just fail during demuxing instead; but
    now it seems there are bugs in these parsers, so disable them to
    avoid bringing their issues along.

    The issue in this case is bad timestamps, but there's no good fix
    for this in the speex code that I can see, so it's simpler to just
    blanket disable.

    Prevent NULL dereference in mov_read_sidx()

    When there are no segments in a sidx, mov_read_sidx() will try to
    dereference a NULL pointer. This patch adds an early return for empty sidx
    boxes.

    Skip trailing junk data when flushing parser.

    The parser should only return valid mpeg audio packets; it generally
    does so, but in the case of flush, it returns whatever happens to
    be in the buffer instead of ensuring its first a valid mpeg packet.

    The fix is to check whether a valid frame size has been parsed and
    if not discard the packet when flushing.

    This should fix all sorts of mp3 files with trailing garbage.

    Add support for building the Windows ffmpeg configuration on Linux!

    This adds cross-compiling support for Windows ffmpeg configurations;
    it also updates the configurations with the generated results!

    This uses a couple of existing Chromium scripts for setting up the
    correct MSVC paths and passing the right cflags and ldflags to
    chromium such that compilation can succeed.

    This also pulls in an upstream patch for configure to make it detect
    the proper command line flag type '/' vs '-':
    https://patchwork.ffmpeg.org/patch/7469/

    There's one further change to the makedef line in configure to
    ensure that it's run using the substituted AR and NM commands
    instead of the defaults lib and dumpbin.

    Explicitly turn off v4l2 in configure.

    configure seems to enable v4l2-m2m even if we explicitly turn it
    off with arguments.

    This CL makes configure check the command-line arguments, and skip
    v4l2 (and v4l2-m2m) if they're turned off.
