Use the new LazyLogModule to instantiate a log for the rust
mp4parse test code instead of using indiscriminate printf()s.
Access results with NSPR_LOG_MODULES=MP4Metadata:5.
Add a helper for passing the initialization segments
of mp4 streams to the rust parser and log the result.
This runs real data through the new parser for testing
but doesn't use the results.
Code is conditional on MOZ_RUST_MP4PARSE to be defined
in confvars.sh. See bug 1219530.
Coercing the shift to a bool makes the comparison useless.
This just affects whether a warning is printed, so there's
no change to what files we accept.
We also need to mask of the high 'Starts with SAP' bit
which is usually set and would replace our false negative
with a false positive. ISO/IEC 14496-12:2012(E) sec. 8.16.3.2
Results of running the new update-rust script.
- Include some #[inline] directives missed in bug 1215234.
- Remove #[crate-name] directive to silence a warning caused
by our building byteorder as a submodule instead of a crate.
Automate update and patching of the rust mp4 parser from the
upstream repo. A rev for mp4parse-rust can be passed on the
command line, but the byteorder crate's version is hardcoded.
Differences to adapt to the gecko build system are applied as
patches like we do for other media code.
Unfortunately cargo isn't much help here. It can download
crates for us, and we can set CARGO_HOME to force it to
use a specific directory, but it doesn't return enough
information to get the versions, etc. without some guessing/scraping
to find the packaged source.
This switches to #[derive(Debug)] for trace println!s, and
updates the C api wrapper to thread through the new MediaContext
as an opaque struct. The idea is to be able to query it later.
'extern crate byteorder' converted to 'mod byteorder'.
DONTBUILD because it only changes comments.
This will hopefully prevent confusion like that in bug 1215903.

Change is just to loop over the input buffer in read_box_from_buffer()
so we parse the entire contents instead of just the first box.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

read_box_from_buffer now returns the (alleged) number of tracks,
or -1 on error instead of a bool. It currently returns 0 for
the test file instead of 2, so I marked that line with an XFAIL
comment for now.
DecoderTraits.cpp pulls in MP3Demuxer.h which in turn pulls in mp4_demuxer/ByteReader.h. In that context, for some reason the ByteReader can't find the definition for MediaByteBuffer unless it is prefixed with the proper namespace.
MP3Demuxer.cpp itself compiles fine, but for some reason in Visual Studio IntelliSense complains about TimeUnit and TimeIntervals being undefined unless the using statement uses the full namespace hierarchy.
Also fix a small typo.

In addition to starting parsing at different points across the input stream,
different sizes are given, from the minimum step size up to the remainder of the stream.

This is less error-prone and somewhat easier to read.
Based on a patch from Joshua J. Drake and suggestions
from Andrea Marchesini.
NB CheckedInt<T>::value() returns a T, so the comparison with
SIZE_MAX should always succeed. Doesn't warn on clang though.
