Now the same pipeline for handling the audio/videos streams will handle
the segmented text streams too. This doesn't apply to the text output,
only to the MP4 variants. This also fixes a bug where we added the
X-TIMESTAMP-MAP tag even when there wasn't TS streams; this doesn't
otherwise change the behavior around that tag.

The test added in the previous CL was broken due to a rebase on another
change. This subtly changed some of the byte offsets that broke the
test. This wasn't caught since I didn't rebase and re-run the tests
before merging.

This changes it from an OriginHandler to a MediaParser and moves the
handling of it to the Demuxer. This will allow more generic handling
of text by giving it the same abstractions as video/audio handling.

In addition to the MediaSample handling of the MediaParser, this now
adds callbacks for TextSample. This allows reading text streams from
the media files.

Instead of having the text readers reading from the file directly, they
now accept the data as a stream.

The Chromium sysroot has a broken C++11 implementation that doesn't
allow us to use <condition_variable> or <chrono>. So we need to use the
system sysroot to use all C++11 features.

The KeySource now only handles fetching the keys and loading any PSSH
info from the license; it will not handle generating new PSSH info
based on the config.
This will allow the PSSH generation to access to the full
EncryptionConfig so we can add additional options to it.

If the user has the GPAC MP4 tools installed, this will use that to
provide a better, text-based diff of the MP4 files. This makes looking
at test failures much better than just "binary files differ".

There were several enum types that all were used for key systems. This
combines them into one to make it more clear and only needing to update
one. This also uses a bit field to specify multiple key systems instead
of using a std::vector.

The resolution values are uninitialized when parsing AVC decoder
configuration record if it does not contain parameter sets (SPS/PPS),
thus they could contain undefined values.
Fixes#750.

Opening a named pipe can block until both ends are open, and we cannot
control when the other end will be open. Ideally, we would always
open files in a thread so that Packager can be used with piped inputs
from naive applications without a potential deadlock.
This change will defer opening WebVTT files until the parser Run()
method is called from a thread. This way, WebVTT files being sent in
from a pipe will never be able to block the main thread.
Previously, files were opened on the main thread before calling the
parser constructor, passing the open file to the constructor as an
argument. I also tried doing it in the parser's InitializeInternal()
method, but that is also called from the main thread.

Under command line flag --mvex_before_trak.
This is needed to workaround Android MediaExtractor bug which
requires |mvex| to appear before |trak|.
Closes#711.

Added --crypt_byte_block, --skip_byte_block to allow users to specify
protection pattern other than 1:9 for pattern based encryption scheme,
e.g. cbcs and cens.

Per https://dashif.org/docs/DASH-IF-IOP-v4.3.pdf 4.4.3.6 Signalling the last segment number in Period, there are three ways to signal the last segment number:
a. Use the lmsg signalling as defined in clause 4.4.3.5.
b. Use the Segment Timeline with @r value greater or equal to 0.
c. Add a Supplemental Descriptor with @schemeIdUri set to http://dashif.org/guidelines/last-segment-number with the @value set to the last segment number.
We do not support (a). This change adds support for (c) when Segment Timeline (b) is not used, i.e. when Representation has constant duration (could be approximate).
Under flag --dash_add_last_segment_number_when_needed (disabled by default).
AV1-ISOBMFF spec is updated recently to use start alignment instead of
end alignment for cbcs:
for the protected scheme cbcs:
- BytesOfProtectedData SHALL start on the first byte and end on the
last byte of the decode_tile structure (including any trailing bits).
- A subsample SHALL be created for each tile, even if its size is less
than 16 bytes.
- ...
cenc protection scheme is not affected.
Closes#698.
