KongQun Yang a6352d4b11 Remove pto_adjustment flag
This flag was introduced to workaround a rounding error in Chrome
(probably in other browsers too).

Also although this flag avoids the first frame of a Period to be
dropped due to rounding error but it could cause the last frame of a
Period to be dropped.

Now that we use a high precision Period@duration, we do not expect to
see rounding errors any more. The player would be a better place for
the workaround even if it is still needed.

Related issue: #368.

KongQun Yang b74e511f29 Workaround for possible rounding errors in MSE
There could be rounding errors in MSE which could cut the first key
frame of the representation and thus cut all the frames until the next
key frame, which then leads to a big gap in presentation
timeline which stalls playback.

Adjusting presentationTimeOffset (PTO) by -1, i.e. backing off PTO by 1
to compensate for the possible rounding error. It should not cause any
playback issues as it is small enough. The workaround can be removed
once the problem is handled in all players.

The PTO adjustment is configurable with command line flag:
 --pto_adjustment, with value set to -1 by default.

Move AdaptationSet related functions to the new Period class, which
maps to <Period> element and provides methods to add AdaptationSets.

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.

KongQun Yang 05a5a41969 Support generation of libpackager.so (shared_library)
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.

Rintaro Kuroiwa 6a7b32641a Get MpdWriter working again
- ContentProtection elements were missing when using MpdWriter,
  therefore mpd_generator also did not generate ContentProtection.
- MpdWriter uses MpdNotifier now, instead of directly using MpdBuiler.
- Add mock_mpd_notifier.{h,cc} to be shared by several tests.

Rintaro Kuroiwa fe851f692b Calculate (sub)SegmentAlignment for AdaptationSets
- AdaptationSet::OnNewSegmentForRepresentation() calculates whether the
  Representations are aligned by looking at the start time and duration.
  (Except that duration is not used in this implementation).
- Add RepresentationStateChangeListener to callback
  AdaptationSet::OnNewSegmentForRepresentation() from Representation.

Joey Parrish 77ec23afe4 Split up AdaptationSets by language.
Additionally, for XML schema correctness, convert ISO-639-2 language
tags (three-letter codes) to ISO-639-1 tags (two-letter codes) when
possible.  This follows BCP-47, which says to always use the shortest
language tag when there are multiple possibilities.
