cec98d4110 mkvparser: Correct the ReadID implementation.
Return real, known MKV IDs when reading them. Previously
IDs were treated as EBML integer values. This was both
wrong and confusing. Wrong because this results in values
that are not part of the Matroska spec, and confusing
because the code was littered with magic numbers
representing the invented IDs.

Currently uses mkvmuxer::MkvId; A TODO in the code addresses this.
Additional IDs have been added that were not previously in the enum:
mkvparser parses many elements that we do not write in the muxer.

841a9b5fd9 mkvparser: Segment assert clean up.
- Remove asserts from ~Segment, CreateInstance, and DoLoadCluster.
- Adds new return constant (E_PARSE_FAILED == -1); most places in
  mkvparser that return -1 are the result of an internal inconsistency
  and/or misusing the API. In those cases E_FILE_FORMAT_INVALID is not
  appropriate as a return value because it's misleading to libwebm users.

0735bb5bdc mkvparser: Make mkvparser namespace usage uniform.
Instead of being weird and defining the first few functions
in mkvparser by explicitly prepending the namespace, open the
namespace immediately and define all functions within it.

83a1f68944 mkvparser: Remove buf_t typedef.
- It is useless.
- It masks errors; buf_t was unsigned char*, but const buf_t was
  not seen by the compiler as const unsigned char*, which allowed
  passing a const pointer as a mutable argument to
  IMkvReader::Read at every site where buf_t was in use.

additionally drop the misguided range check; this is meant as a data
