SectionPayloadReaders are provided to a SectionReader to
get whole sections(crc checked). This allows the injection
of custom section readers. E.G: SCTE35 messages.

In this CL:

* PesReader moves out of TsExtractor and becomes public.
* ElementaryStreamReaderFactory becomes TsPayloadReaderFactory and is
    moved to TsPayloadReader.
* The TsPayloadReaderFactory is in charge of wrapping any
    ElementaryStreamReaders with a PesReader.

Incoming:
* Extract SectionReader supperclass (analog to PesReader, but for
    sections) from Pat and Pmt readers.
* Add a ScteReader, wrapped by a section reader, and include it in
    the DefaultTsPayloadReaderFactory.

Fix NPE in TsExtractor when ElementaryStreamReaderFactory returns null

pesPayloadReader can be null here because DefaultStreamReader.init() can return null on unknown streamId. If we have a junk transport stream in our content an exception will be thrown.

*** Reason for rollback ***

Flag doesn't enforce what it says it enforces, due to redirects

*** Original change description ***

Add REQUIRE_HTTPS flag

Note that it's not possible for the library to enforce that
the flag is adhered to, since it's possible for applications
to inject custom implementations of DataSource (there's no
requirement they even extend HttpDataSource for network
requesting implementations). It's possible for applications
to replace pretty much anything in the library, so there's
no other place we could put the flag where we could make
this guarantee. Hence this is a best-effort that will work
when...

This is a problem when two invocations of getNextChunk that retrieve
chunks (i.e. not playlists) occur too apart in time. In that case
the last loaded chunk has a media sequence that is behind the current
playlist.

One issue with the previous implementation was that
isUnsynchronized would not be set back to false if
previously set to true and if the next header has
majorVersion >= 4. In general, having the decoder be
stateless is clearer (and thread safe, albeit that
this property is not required).

1. HttpMediaDrmCallback.executeProvisionRequest needs to specify
   an empty byte[], else we do a GET instead of a POST.
2. Content-Type should not be set when making the provision
   request, since there's no body.
3. DataSource implementations must correctly handle a non-null
   body with zero length. CronetDataSource was not handling this
   case. DefaultHttpDataSource was, but made a code modification
   to make it a little clearer. OkHttpDataSource seems to handle
   the case correctly, and it doens't look like the code can be
   made clearer.

Note that actually handling CEA-708 is not yet implemented,
and so this is a no-op change from a behavior point of view.
