KongQun Yang c9fb2b4a85 Use start_time from CueEvent in NotifyCueEvent
Instead of using next segment start time, as CueEvent time may not
align with segment start time exactly.

Also remove the incorrect DCHECK in ChunkingHandler when processing
kScte35Event.

KongQun Yang 8e96dd3b37 Address gcc build failures in some platforms
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.

Fixes #286
Fixes #293

Aaron Vaage 31bf6dab59 Separate MediaHandlerTestBase From FakeMediaHandler
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.

Aaron Vaage 16eff80497 Made StreamData Have Const Pointers
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.

Kongqun Yang 9990524f98 Implement ChunkingHandler
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.
