For background on why doing this works, see below. I don't want to change
how we get our Cipher instance in non-test code, since PKCS7 always works
on Android. It's only when the tests are running on a non-Android host
machine that they can fail. An alternative would be to make it an androidTest,
but androidTests are slow.
------
Background:
"While Java considers PKCS5 and PKCS7 padding to be the "same" (and
one should always use the string "AES/CBC/PKCS5Padding" because
"AES/CBC/PKCS7Padding" will cause NoSuchAlgorithmException to be thrown
when initializing an AES block cipher using the Java crypto API), I
consider this a gross misnaming in the Java platform because the pure
technical definitions of these paddings are not the same."

The new method allows to add TransferListeners after the DataSource
has been created. Most implementations just forward to their wrapped
upstream DataSource. Implementation which directly read data implement
BaseDataSource instead.
Also removes the temporary default no-op implementation in DataSource.

1. Copy label into derived formats
2. If audio is the primary track type, copy additional fields from
the variant formats. This is probably a no-op in practice, since
I don't think variant formats have these fields set anyway, but
it seems like the right thing to do in case they ever are set in
the future.
Note: It's a bit strange to use createXContainerFormat rather than
createXSampleFormat, but in practice the methods used here are
better matched for what we're trying to do.

1. Prefer label and language values in the manifest to those in
the media. This is particularly helpful if the sample format
contains "und" as the language.
2. Copy label when deriving formats in HlsSampleStreamWrapper
3. When there's only one variant in HlsSampleStreamWrapper, use
the regular copyWithManifestFormatInfo. This allows more
information to be retained from the sample format.

If the EXT-X-INDEPENDENT-SEGMENTS tag appears in a Master
Playlist, it applies to every Media Segment in every Media
Playlist in the Master Playlist.

This requires propagation of attributes from the master
playlist to the media playlists. This CL only includes
independent segments, but other inheritable attributes
will be supported in following changes. Other inheritable
attributes include variable substitution definitions and
session keys.

If a MediaPeriod uses a Loadable, then there are typically
reference chains of the form:
LoadingThread[GCroot]->Loadable->MediaPeriod->Player
Where the player is the MediaPeriod callback. When the
player is released, this reference chain prevents the
player from being GC'd until Loadable cancellation
completes, which may not always be fast. This in turn
will typically prevent the application's activity from
being GC'd, since it'll normally be registered as a
listener on the player (directly or indirectly via
something like a view).
This change mitigates the issue by removing references
that the MediaPeriod holds back to the player. The
MediaPeriod will still not be eligible for GC, but the
player and application activity will be, which in most
cases will be most of the leak (in terms of size).

This simplifies Loadable implementations, and also removes the
possibility of an incorrect Loadable implementation causing the
wrong Loader.Callback method being called (perviously, for the
correct method to be called, we relied on isLoadCanceled being
implemented correctly).

Currently, the sample queues are lazily enabled when they are first read from.
This causes problems when the player tries to discard buffer and the
HlsSampleStreamWrapper assumes the sample queue is disabled even though it's
actually enabled but hasn't been read from.
This change moves setting the sample queue index of the sample stream back into
HlsSampleStreamWrapper. It enables the sample queues at track selection if the
queues are already built, or immediately after they have been built for
chunkless preparation.

Open was not calling through to upstream.open. This was not problematic for
reading, because DataSourceInputStream.read would open the upstream if it's
not open already. It was however a problem for calling getUri() between
calling open and the first call to read, which would end up calling
upstream.getUri() on the not-yet-opened upstream.
