Instead of relying solely on asserts, which compile away to
nothing in downstream projects using libwebm for parsing webm
input streams, actually check for the conditions being asserted,
and return errors when appropriate.

sample_muxer was using the buffer size instead of the frame payload size
when passing frames to the muxer.

Re-run clang-format to pick up some missed changes over the past
few CLs. Also update the .clang-format file to break after ternary
operator.

Fix EBML lacing block parsing when attempting to parse the last frame
on single-frame videos and assertion when frame_count is lower
than actual data in the file.
Change-Id: I223e30be54970ef75126c6c4ee3401cbeb92e02f
Fixed block parsing to account to cases that would
allow frame_size = 0, only to be rejected later on
Block::GetFrame assert(f.len > 0);

Malformed files woudl cause the parser to assert.
Instead now it stops parsing and skips the segment.
Change-Id: I256b3b72e43f969693ae16547ca98da07d665e21
Changed assertions to "invalid file format" errors files that
had Block Groups without Block IDs or had invalid sizes or
durations

Per matroska semantics, all metadata blocks should be considered
key frames. Set it to true in AddMetadata functions.

Use Segment::AddGenericFrame to add frames to the output file. The
other AddFrame* functions will soon be deprecated and this will be
the preferred way of adding frames.

Malformed files would cause the parser to assert.

this is unused as the size of dates is fixed:
Date - signed 8 octets integer in nanoseconds with 0 indicating the
precise beginning of the millennium (at 2001-01-01T00:00:00,000000000
UTC)

previously IsValidTrackNumber() expected a track_number > 0
this also fixes a warning:
'comparison of unsigned expression < 0 is always false'

Refactor muxer to remove a lot of duplicate code. This CL strives
to not change the API as much as possible. Although, there is one
minor public API change (constructor of the Cluster class). Other
than that, all the functions should work exactly the same way as
before.
Following up on this CL, we are going to make AddGenericFrame the
preferred way of adding frames to a segment and deprecate (and
eventually remove) all the other specific AddFrame* functions.
Change-Id: Ie410f1a64a981e1545ade53ce476bbe8b3610c4f
Rename variable "frame" to "data" in all the AddFrame* functions.
This is in prepararation for a follow-up CL.

If a malformed webm file contains invalid information on the Cues
the segment, the parser would assert.
Instead, now it ignores the Cues and skips the segment.

The existing CMakeLists.txt ends up generating a static library
with name "liblibwebm.a" rather than "libwebm.a". This patch fixes
it.

- These files facilitate project/makefile generation.
- Remove old Visual Studio projects.
- Rename Makefile to Makefile.unix.

The third parameter of the MoveCuesBeforeClustersHelper recursive function
should always be the size of the cues element without the master element's size
(i.e.) it should be the sum of size of all Cue Points. This way, the changes in
the Length of the master element itself will be computed correctly.

previously only empty clusters of known size were accepted; with
clusters of unknown size the cluster has been successfully parsed and a
working copy of the file position updated, so parsing can continue.
clusters of this type are discarded as clusters of known size currently
are.
