This replaces Travis (for Linux & Mac) and Appveyor (for Windows) with
GitHub Actions. In addition to using GitHub Actions to test PRs, this
also expands the automation of releases so that the only manual steps
are:
1. Create a new CHANGELOG.md entry
2. Create a release tag
Workflows have been create for building and testing PRs and releases,
for publishing releases to GitHub, NPM, and Docker Hub, and for
updating documentation on GitHub Pages.
When a new PR is created, GitHub Actions will:
- Build and test on all combinations of OS, release type, and library
type
Appveyor's workflow took ~2 hours, whereas the new GitHub Actions
workflow takes ~30 minutes.
When a new release tag is created, GitHub Actions will:
- Create a draft release on GitHub
- Extract release notes from CHANGELOG.md & attach them to the
draft release
- Build and test on all combinations of OS, release type, and library
type, aborting if any build or test fails
- Attach release artifacts to the draft release, aborting if any
one artifact can't be prepared
- Fully publish the draft release on GitHub
- Publish the same release to NPM (triggered by GitHub release)
- Publish the same release to Docker Hub (triggered by GitHub release)
- Update the docs on GitHub pages

In e2efb5d4, I fixed shared_library builds on Windows, but I
introduced another issue in which the libpackager_type variable was
not correctly defined by default. This meant that the build only
worked with this variable explicitly-defined in GYP_DEFINES when
gclient sync was run.
This fixes the default definition so that libpackager_type does not
need to be defined explicity.

Shared library builds worked, but failed tests because they were made
with the wrong CRT linker settings. Strings allocated within the
library could not be freed outside the library because the dynamic CRT
was not used.
This sets necessary gyp variables to link with a dynamic CRT on
Windows, thereby fixing tests running in shared library mode that
otherwise hung in a GitHub Actions environment.

To make shared_library builds work on Windows with MSVS 2019, this
commit:
- Silences a useless warning about a private member in dll-exported
Status class.
- Exports the File class used by packager.exe
- Removes the explicit File dependency in packager.exe in favor of
libpackager, now that File is exported
- Add missing defines in packager.exe and packager_test.exe that
instruct the linker to import Status and File from the library

Because a StreamState object contains a unique_ptr, it is not
copyable. A vector of StreamStates, therefore, causes a compile error
on resize or push_back, both of which invoke the copy constructor.
I don't know why MSVS complains, but clang does not.
To fix this, I'm changing vector<StreamState> into deque<StreamState>.

Note that this only supports a single page within the DVB-sub stream.
Multiple pages will be merged together. A follow-up will allow
selecting a specific page.
This only supports outputting using TTML or MP4+TTML; you cannot have

uses images, it is hard to impossible to do this with WebVTT.
This also only supports interlaced images, not progressive images
nor text.

The reference count in 'sidx' box is a uint16 field, which allows at
most 0xFFFF entries, i.e. at most 0xFFFF subsegments, which is roughly
18 hours for one second segments.
Do not fail packaging when it happens. Instead, generate a warning and
truncate the number of references to 0xFFFF instead.
Note that the actual number of mp4 fragments in the mp4 file can still
be more than 0xFFFF. The stream will not play to the end in DASH, but
it will play successfully in HLS.

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.

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:

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.

HLS uses the EXT-X-MEDIA-SEQUENCE tag at the start of a live playlist in
order to specify the first segment sequence number. This is because any
live playlist have a limited number of segments, and they also keep
updating with new segments while removing old ones. When a player refreshes
the playlist, this information is important for keeping track of segments
positions.
When the packager starts, it naturally starts this count from zero. However,
there are many situations where the packager may be restarted, without this
meaning starting this value from zero (but continuing a previous sequence).
The most common situations are problems in the encoder feeding the packager.
With those cases in mind, this parameter allows to set the initial
EXT-X-MEDIA-SEQUENCE value. This way, it's possible to continue the sequence
number from previous packager run.

Segment start,end time was used previously, which could result in
problems if there are discontinuity in the streams. E.g. if the
stream has timestamp, 10000, 10001, 10002 and then next segment
comes in with timestamp 1. With the previous logic, all the segments
would remain in the time shift buffer until after 10000 segments
even with a small time shift buffer depth of 10.
This could also happen when timestamp wraps around, which could
happen during long time of live streaming.
