- Remove the TS key rotation not supported check as there is nothing
to be done for key rotation in TS for SAMPLE-AES.
- Fix IV updated problem in new segments even if crypto period does
not change.
- Avoid duplicate EXT-X-KEY tags if it does not change.
- Make EXT-X-DISCONTINUITY-SEQUENCE match with number of removed
EXT-X-DISCONTINUITY.
- Added end to end test for HLS with key rotation.

The HLS manifests output by the packager did not have the RESOLUTION
attribute on EXT-X-STREAM-INF tags. This change adds the resolution
tag when resolution values are present.

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.

'availability_time_offset' is not an attribute in MPD specification,
but used to calculate availability_start_time to adjust segment
availability time. A similar effect can be achieved with standard
blessed suggested_presentation_delay flag.
If suggested_presentation_delay is not set, player is expected to
choose a suitable value.

This addresses playready broken with clear lead = 0.
clear lead != 0 is still broken with playready on Edge. We think it is
likely an Edge bug, which does not support multiple sample entry boxes,
thus does not support clear lead.

Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
tracks

Allow or disallow reusing UDP sockets. Default 0.
- interface=a.b.c.d
Address of the interface over which to receive UDP multicast
streams.
- timeout=microseconds
Timeout in microseconds. Default to unlimited.
A UDP url should be of the form udp://ip:port[?options], here
is an example:

Language tags can have subtags, such as "por-BR". While the base tag
should be 3 characters, the entire tag can be longer. Rather than
parse out the base tag and check that it is size 3 without the subtag,
we can just trust the ISO tag converter to do the right thing.
