To remove the direct dependencies between packager.cc and the different
muxer implementations, this change remove the muxer factory to its
own file.

Moved all code dealing with jobs into its own class so that the
packager code does not need to worry about initializing, running,
or stopping jobs.

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.

Audio samples per frame for AC3 was not specified correctly earlier.
Also the number of channels is not correct if LFE channel is on.

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.

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.

- Also fix the misleading error if an invalid input is provided
The command line app now correctly reports that the file is not
found instead of stream not available.

This is what webm_subsample_encryption flag actually does.
- Fixes the flag not working problem introduced by previous CLs.
- Also mark flag webm_subsample_encryption as deprecated.

Also moved MediaHandler output validation to Initialize instead.
This CL also addresses #122 with consistent chunking.
Change-Id: I60c0da6d1b33421d7828bcb827d18899e71884ce
This handler is a multi-in multi-out handler. If more than one input is
provided, there should be one and only one video stream; also, all inputs
should come from the same thread and are synchronized.
There can be multiple chunking handler running in different threads or even
different processes, we use the "consistent chunking algorithm" to make sure
the chunks in different streams are aligned without explicit communcating
with each other - which is not efficient and often difficult.
Consistent Chunking Algorithm:
1. Find the consistent chunkable boundary
Let the timestamps for video frames be (t1, t2, t3, ...). Then a
consistent chunkable boundary is simply the first chunkable boundary after
(tk / N) != (tk-1 / N), where '/' denotes integer division, and N is the
intended chunk duration.
2. Chunk only at the consistent chunkable boundary
This algorithm will make sure the chunks from different video streams are
aligned if they have aligned GoPs. However, this algorithm will only work
for video streams. To be able to chunk non video streams at similar
positions as video streams, ChunkingHandler is designed to accept one video
input and multiple non video inputs, the non video inputs are chunked when
the video input is chunked. If the inputs are synchronized - which is true
if the inputs come from the same demuxer, the video and non video chunks
are aligned.

- Deprecated command line flags --profile and --single_segment.
'segment_template' in stream descriptors implies live profile
and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
static mpd for live profile; if not set, dynamic mpd will be
generated.

- 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.

- Disallow packager_test.py to be executed from source directory
- Remove the building of packager target from packager_test.py. User
need to make sure packager builds successfully before running
the test.
- Remove build_type parameter which is no longer needed

Profiling can be enabled by setting profiling=1 in gyp, e.g.
GYP_DEFINES="profiling=1" gclient runhooks
To turn on heap profiling, use the HEAPPROFILE environment variable
to specify a filename for the heap profile dump, e.g.
HEAPPROFILE=/tmp/heapprofile out/Release/packager ...
To turn on cpu profiling, use the CPUPROFILE environment variable
to specify a filename for the cpu profile dump, e.g.
CPUPROFILE=/tmp/cpuprofile out/Release/packager ...
Note that profiling may not work for debug builds, so use release
build if possible.
See docs/linux_profiling.md for details.
This change will help identify and resolve problem behind Issue #61.

- Width/Height in tkhd box should be display resolution instead of
coded resolution.
- pasp was not generated earlier.
- Assuming SAR as 1:1 if it failed to be extracted successfully.
- Also update test files for mp4_media_parser_unittest.
This fixes Issue #35.
