Ok, I've merged the matroska patches now. I'll merge things from the vp8
encoder/decoder plugin to gst-plugins-bad later...

    matroskamux: bump default doctype version to 2

    In this day and age this should be safe. There's otherwise a risk people
    will be creating unneccessarily big WebM files as they can't use
    SimpleBlock in v1.

    matroska: handle matroska and webm doctype versions equally

    The original plan was to let WebM v1 be the same as Matroska v2 (with
    extra constraints), but for simplicity it was decided to handle the
    versions equally, such that e.g. SimpleBlock is only allowed in WebM v2.

    matroskademux: Verify lace size in _parse_blockgroup_or_simpleblock

    Failure to do this for corrupt input can cause a subbuffer bigger
    than the actual buffer to be created, quickly leading to segfault.

    ebml: crude hack to avoid crashing on unexpected metadata

    The comment says this cannot happen, but it did and I don't know
    why. This is not the correct fix, needs investigation. Test case:

    ebml: don't modify out str if returning an error in _read_ascii

    This is a regression from ASCII validation changes. Test case:
    bug_s66876390_r0.001____malloc_printerr.webm

    ebml: Validate 7-bit ASCII in gst_ebml_read_ascii

    This was triggering an UTF-8 assertion in gst_caps_set_simple for
    corrupt files with garbage as codec id. Test case:
    gstreamer_error_trying_to_set_invalid_utf8_as_codec_id.webm

    Old gst_ebml_read_ascii renamed to gst_ebml_read_string, also used by
    gst_ebml_read_utf8. Unlike for UTF-8, failure to validate is an error,
    as gst_ebml_read_ascii is used for reading doctype and codec id and we
    might just as well give up early in those cases.

    matroskademux: Ignore unexpected CodecState

    Because GstMatroskaTrackContext *stream is set up in the first
    SimpleBlock or Block, a rogue CodecState otherwise causes a segfault on
    derefencing the NULL pointer. Test case:
