Move "struct bstr" definition from ebml.h to its own header and add
some utility functions/macros. Change length field type from int to
size_t and adjust using code accordingly.
Partially based on a patch from Anton Khirnov.
Add a new EBML parser implementation that should allow significant
improvements to the Matroska demuxer. The new parsing code is not
actually used yet by the demuxer. The only changes to existing code in
this commit are to generate the MATROSKA_ID_* / EBML_ID_* macro
definitions from the new implementation and to rename some of them
(the new implementation uses names matching the official Matroska spec).
The main parser implementation is added in ebml.c. There are two new
generated files, ebml_defs.c and ebml_types.h, that contain
definitions of EBML elements. Those are generated by the new script
TOOLS/matroska.py. There's a new Makefile target "generated_ebml" that
run the script to refresh the content of the generated files.
Add code to intelligently choose an appropriate Matroska edition when
there are several. Will choose, in descending order of preference: the
edition chosen by the user through the option "-edition <edition id>"
if it exists, the first edition with EditionFlagDefault set to 1 if
there is one, or the first edition.
Detect use of ChapterSegmentEditionUID element in a Matroska chapter
definition, indicating inclusion of an external virtual timeline,
which is not yet supported. Leave the chapter is the chapter list but
set segment_uid to zero. This way timeline parsing will skip the
chapter and avoid nonsensical output but will still print information
about missing content.
