Joey Parrish cfbe5c08c2 cleanup: Convert all time parameters to signed
This converts all time parameters to signed, finishing a cleanup that
was started in 2018 in b4256bf0.  This changes the type of:
  - timestamps
    - PTS specifically
  - timestamp offsets
  - timescales
  - durations

This excludes:
  - MP4 box definitions
  - DTS specifically

This is meant to address signed/unsigned conversion issues on arm64
that caused some test cases to fail.

KongQun Yang 10daa39901 [MP4] Allow not to generate 'sidx' box for single-segment too
I.e. the flag --generate_sidx_in_media_segments,
--nogenerate_sidx_in_media_segments work for both single-segment
and multi-segment mode with this change.

Related to #862.

KongQun Yang 772aa7c93f Do not force earliest_presentation_time to 0 for VOD
Instead, the actual earliest presentation time is used except for
the first segment if there is an offset between presentation time
(pts) and decoding time (dts).

Chrome (as of v66) reports dts instead of pts in buffered ranges in
MSE API. To avoid breaking Chrome, the earliest_presentation_time
of the first segment is set to its dts as Chrome does not like negative
values for
  adjusted dts = dts + Period@start (0 for the first period)
                 - presentationTimeOffset (earliest_presentation_time).

Fixes #303.

KongQun Yang 9c861d03f7 Report an error when disk is full
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.

Fixes #160

Rintaro Kuroiwa 0dfdace280 Change MuxerListener::OnMediaEnd to take ranges
- Changed OnMediaEnd() to take (sub)segment ranges.
- Define a structure to pass the ranges.
- This requires muxers to "cache" the segment ranges but in most cases,
  they already do it, e.g. 'sidx' for mp4.

  MuxerListener.
- Change MuxerListener::OnEncryptionInfoReady() to take an
  initialization vector.
- Change MuxerListener::OnNewSegment() to take segment name.
- Reworded and formatted MuxerListener comments to Doxygen style.

Kongqun Yang 336435fcca Address one sample fragment issue #33
The segment duration was not reset after segment was finalized. It
was reset after adding one sample. This new sample was added to the
new fragment but was not recorded in the new segment, which resulted
in off-by-one error in the segment generation.

Matt Brannock 6a7c6a3f7a Use bytes_read == 0 instead of EoF()
Due to various libraries' inconsistencies with using EoF, this change
will instead continue to read a file until the number of bytes read is
0. It considers bytes_read == 0 to mean end of file.
