LOG(FATAL) aborts the executable, which means gtest can't write any
reports it might be configured to write when tests are complete. This
will interfere with reporting.
This converts the only use of LOG(FATAL), which was in
ReadTestDataFile(), to LOG(ERROR). This also updates test cases to avoid
crashing when ReadTestDataFile() returns an empty buffer.
Note:
* An xHE-AAC capable encoder will auto adjust the user-specified SAP/RAP
value to the allowed grid where SAP/RAPs can occur.
e.g.: `-rapInterval 5000` (5s) may result in actual SAPs/RAPs every
4.984s.
* To ensure SAP/RAP starts a new segment, Shaka needs to executed with a
"--segment_duration" is less than or equal to that adjusted value.
* If every SAP/RAP should trigger a new segment, just set the segment
length to a very low value e.g.: `--segment_duration 0.1`

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.

- Define BaseDescriptor and generic read / write operations.
- Define descriptors: ESDescriptor, DecoderConfigDescriptor,
DecoderSpecificInfoDescriptor, SLConfigDescriptor.
DecoderSpecificInfoDescriptor and all other descriptors can now
handle arbitrary length size, not limiting to 64 byte for
DecoderSpecificInfoDescriptor, which was placed to limit
ESDescriptor length size to one byte.
- Now DecoderConfigDescriptor is able to handle reading and writing
of all fields including buffer_size_db, which was not handled
earlier.

This is a more faithful implementation of more_rbsp_data().
There could be trailing null bytes in NAL units. This isn't valid per
H264 specification, but the referenced bug includes a sample where the
PPS in the avcC record includes a trailing null byte.
Workaround the problem so packager does not fail.
A similar problem is workarounded in Chrome:

In H265Parser::ParseSliceHeader, the parser does not handle
byte_alignment() from the spec. byte_alignment() reportedly contains
at least one bit, which is not handled right now.
See Section 7.3.2.12 Rec. ITU-T H.265 v3 (04/2015).
Also added a few size sanity checks in H265Parser to make sure the
code does not crash if an invalid input is provided.

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.

- This fixes the issue when one NAL unit has multiple
subsamples, which is allowed in spec and could happen
when the clear_bytes exceeds 2^16 bytes.
- The new algorithm updates the subsample entries in
following steps:
1) When NaluReader parses a new NAL unit, the
function splits subsamples and align them with the
NAL unit. It also finds the range of subsamples
for that NAL unit.
2) Drop or update subsamples of that NAL unit,
based on the type. Other inserted bytes are treated
as a new all-clear subsample.
3) Merge those subsamples if possible.
- This addresses #237.

Shared libpackager can be built by setting libpackager_type to
shared_library, e.g.
GYP_DEFINES='libpackager_type=shared_library' gclient runhooks
ninja -C out/Debug
will generate libpackager.so in out/Debug/lib directory.
Here is a few other changes to make shared_library builds and
tests pass:
- Add several test parameters to packager.h, which is needed for
testing.
- Create a protoc.gypi from build/protoc.gypi but depending on
protobuf_full_do_not_use instead of protobuf_lite, since we need
protobuf_full_do_not_use for text parsing and generation of media
info proto. Somehow shared_library build does not allow mixed use
of protobuf_full_do_not_use and protobuf_lite.
- Remove the use of LazyInstance in version/version.cc and use static
variable directly. This is because LazyInstance needs AtExitManager
which may not be easy to setup when calling GetVersion.
- Allow skipping testPackageWvmInputWithoutStrippingParameterSetNalus
with flag --shared_library, which is needed as shared_library build
does not support --strip_parameter_set_nalus flag yet.

- The flags were overwritten in a loop and therefore only stored the
last value of the flag.

Change-Id: I59762d7c84bc3d81bf3b0b5e85ffe689260d970a
Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.
Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.
The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.
Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.
