Previously we would get a new AudioTrack and flush all audio processors if any
AudioProcessor needed to be flushed on reconfiguration. This was problematic for
the case of TrimmingAudioProcessor because it could become active or inactive
due to transitioning to a period with gapless metadata or without it (we don't
keep it active all the time because it is wasteful to populate its end buffer
for content that is not gapless).
This change handles the case where we don't need an AudioTrack but
AudioProcessors do need to be flushed. In this case we drain all the audio
processors when next handling data then switch to the new configuration.
This avoids truncation when period transitions change whether
TrimmingAudioProcessor is active but don't require a new AudioTrack, and is also
a step towards draining the AudioTrack when transitioning between periods if we
do need a new AudioTrack.
To do this, it needs to be possible to drain any pending output data from an
AudioProcessor after it's configured to a new format, so this change makes sure
AudioProcessors allow calling playToEndOfStream and getOutput after
reconfiguration and before flush.

- Remove unused TAG
- android.Theme.Material can only be used from API level 21
- Rm "Base" from activity name for consistency

Some module/extensions couldn't use the static test so far because all files
needed to be put on the blacklist. To ensure the test it set up for all
modules, this fixes at least one file for each of the modules.

- Ensure that no memory is used by audio processors that are always inactive, by
only allocating in flush() if active. If data was already allocated but a
processor becomes inactive we assume that the allocation may be needed in
future so do not remove it (e.g., in the case of ResamplingAudioProcessor).
- Make SilenceSkippingAudioProcessor set up its buffers in flush(), and clarify
that it is always necessary to call flush() if configure() returns true.
- Make reset() reset all state for all processors.
- Use @Nullable state or empty arrays for inactive audio processor buffers.
- Miscellaneous style/consistency cleanup.

This is not really useful with the DefaultAudioSink, but could be used in a
custom AudioSink when mixing audio from sources that have different sample
rates.
