Some subtitle files use .webvtt instead of .vtt, probably because
ffmpeg uses -f webvtt when converting from some other format.

- Also regenerated test content to insert an iframe every one
second: ffmpeg -i source.webm -auto-alt-ref 1 -g 30 out.webm
This makes sure the content is actually encrypted with one
second clear lead in end to end test.

- Add decrypt_config in media sample and stream.
- Update subsamples when converting NAL unit to bytestream.

1. Replace STLDeleter with unique_ptr in container, which is
supported in C++11
2. Replace string_as_array with &string[0] which is guaranteed
to work in C++11

The current behavior of logging to a file in the same directory
as the binary will break if the binary does not have write access
to that directory.
Fixes Issue #139

In H264, there may be multiple consecutive video slice NAL units
in the same frame. The original code assigns a new access unit
for every video slice NAL unit, which is incorrect.
Fixes#134.

Mimic iso-bmff behavior: either all the samples in a segment are encrypted
or all the samples are clear.

The right way to detect the presence of a keyframe in a BlockGroup
is to look for the absence of the ReferenceBlock element [1].

Also updated packager_test not to fill in output_format by default,
which will help catch these kinds of bugs.
Closes#130

This flag is needed to workaround the Chromium bug
https://crbug.com/398130, which uses decoding timestamp
in buffered range.

Packager should not care about this flag, whether it is supported
is up to the decoder.

- Add MuxerListener::OnEncryptionStart() for notifying that further
segments are encrypted.

- Cannot include PMT for following encrypted segments in the clear lead.
Some players consider them as conflicting codecs.
- Add EXT-X-DISCONTINUITY in front of first EXT-X-KEY to notify that the
codec is switching from e.g. "avc1" to "zavc".

Before, we converted the WebM configuration to MP4 in the video
client, however this lead to a bug when fields were missing. So
now don't convert until the cluster parser so the extra info from
the stream can be added.
This also fixes a bug where the value was not printed in the warning
logs.

Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

Although superframe index is not encrypted, it should still be inserted
into subsamples list (with cipher_bytes as 0).

- Add flags and stream descriptor fields for HLS.
- Remove fields from MuxerOptions. Instead pass them directly to
HlsNotifyMuxerListener.
- Rebase segment names to the master playlist's path where it makes
sense.
Change-Id: If4f54bc56ff46dc6140859a79ed66f7b99112ed7
- Tracks other than video are protected using whole-block full-sample
encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
equivalent to a pattern of 1:0. This is different to the non pattern
encryption counterparts.
- Also updated the code to allow the existence of other protection
schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.

This is part of the effort to support Opus in iso-bmff #83.
Changes in this CL:
- Add support for multiple SampleGroupDescription and SampleToGroup
boxes in TrackFragment box;
- Add support for SampleGroupDescription and SampleToGroup boxes
in SampleTable box;
- Add support for AudioRollRecoveryEntry in Sample Group and 'roll'
sample grouping type;
- Also fix a bug that default length was not set correctly in
SampleGroupDescription when constant iv is used.
