when defining its constructor and destructor in its
header file.

This change introduces handlers to output WebVtt text files. There is
only one output but there is a common base to support others.
WebVttOutputHandler which handles all communication with other handlers
and WebVttSegmentedOutputHandler is responsible for listening for events
and choosing when and where to write cues and headers.

Instead of having multiple char readers, one for strings and
one for files, just have one for files and use memory files
when testing.

To better align with the Chunking Handler, the Text Segmenter
now outputs the SegmentInfo at the end of the segment rather
than the start.

Implemented a MediaHandler that takes text samples and creates
media samples. The data in each media sample is the MP4 box for
non-overlapping cues.
As per WebVtt in Mp4, all cues must be non-overlapping. This handler
takes care of grouping and dividing cues.

This change creates the webvtt segmenter which will be used for
segmented text webvtt for HLS. It takes a stream of text samples
and injects segment info messages based on the segment duration.
It is possible for samples to extend between segments, if so the
sample will appear twice (once in each segment).

Took the WebVTT Media Parser and created the WebVTT Parser
that will take in a file and output a stream of cues that
will later be passed to another Media Handler that takes in
cues and chunks them.

Seeing some failures on some platforms when compiled with clang
disabled:
GYP_DEFINES="clang=0" gclient runhooks
Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
direct control: dangling-else, deprecated-declarations,
unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
all linux distributions.

1. Expect the time elapsed to be greater than kTimeout instead of
approximately equal to kTimeout if there is a "wait";
2. Expect the time elapsed to be smaller than kTimeout instead of
approximately equal to 0 if there is no "wait".
Also rename a variable in packager.cc to better reflect what it is.

The error is logged only once to avoid log spamming.
Added definitions for the unsupported stream types for easy look up.

This patch also fixes a bug which was introduced in
https://widevine-internal-review.googlesource.com/c/packager/+/38040
where it was inconsistently assumed that AdCueGenerator would be MIMO
while connecting with other handlers and at the same time it was assumed
SISO in the AdCueGenerator class. Now we assume SISO everywhere.

The keys can be specified in --keys option, with the form of
label=<label>:key_id=<32-digit hex string>:key=<32-digit hex string>,label=...
There can be multiple "label=..." block. The DRM label can be one
of "AUDIO, SD, HD, UHD1, UHD2" or a custom label.
Mark --key and --key_id as deprecated. We can achieve the same result
with --keys=label=:key_id=<key_id>:key=<key>.
Also add a new optional field in stream descriptor: drm_label, which
is used to overwrite the internally generated DRM label for the stream.
If not provided, the DRM label is generated automatically based on
audio/video information, e.g. resolution.
Code changes:
- Merged RawKeyEncryptionParams and RawKeyDecryptionParams into
RawKeyParams.
- Make FixedKeySource accepts RawKeyParams as input.

Use std::shared_ptr<const uint8_t> with a custom deleter to
represent MediaSample::data_ instead of std::vector<uint8_t>.
MediaSample::data_ can be shared by multiple MediaSamples and it is
immutable. A new data instance must be created if the clients want to
modify the underlying data. The new data instance can be transferred
to MediaSample using provided MediaSample::TransferData function.
This avoids unnecessary data copying.

Took the test structure for trick play and made a common test
structure that can be used for new tests. The next tests to
use this structure will be the new WebVtt pipeline.

Before the trick play handler would have one input and multiple
outputs. The normal media handler API for adding handlers had to
be ignored when setting-up the trick play handler.
This changes the trick play handler to have one input and one output.
It uses the standard AddHandler method calls. When initialized, the
trick play factor must be provided.
This included a run of 'clang-format' over all edited files.

To allow more tests to use the MediaHandlerTestBase and get access to the
helpful creation methods, this change moves the use of FakeMediaHandler
and setting up the graph to a sub class.

Created media handlers that make testing a handler easier by providing
methods to send messages from upstream and check messages downstream.
Change-Id: I7b3ba3a51bcf0d73bcaacd46b2dcbc16f87d8694
In prep for changes to Trick Play, we want to make all messages
copy on write so that if the same message is sent to multiple
handlers, it is not possible for one handler to change the data
another handler is using.

Previously packaging completes successfully without any error
or warning.
With the fix, an error will be reported if write fails. It may
appear as "Cannot close file error" as we use threaded IO, which
could delay the error reporting until Close() call, so the user
of the File API needs to make sure Close() returns successfully.
Also fixed a deadlock in threaded_io_file if internal_file->Write
fails.
