- When in STATE_SEEK with targetGranule==0, seeking would exit
without checking that the input was positioned at the correct
place.
- Seeking could fail due to trying to read beyond the end of the
stream.
- Seeking was not robust against IO errors during the skip phase
that occurs after the binary search has sufficiently converged.

A previous change switched to calculation of the bitrate based on the
first MPEG audio header in the stream. This had the effect of fixing
seeking to be consistent with playing from the start for streams where
every frame has the same padding value, but broke streams where the
encoder (correctly) modifies the padding value to match the declared
bitrate in the header.

- Test seeking to (timeUs=0, position=0), which should always work
and produce the same output as initially reading from the start
of the stream.
- Reset the input when testing seeking, to ensure IO errors are
simulated for this case.

Two tests have very low propability flakiness (1:1000) due to not waiting for
a seek in one case and the chance of already being ended in another case.
Fix these and also adjust wrong comments about state changes.

These values can easily default to the empty track group and the empty
selection. As a result we can remove restrictions about not calling
holder.getTrackGroups before the period finished preparation.

Android considers ALAC initialization data to consider of the magic
cookie only, where-as FFmpeg requires a full atom. Standardize around
the Android definition, since it makes more sense (the magic cookie
being contained within an atom is container specific, where-as the
decoder shouldn't care what container the media stream is carried in)

Checking inputPosition == 0 isn't sufficient because the synchronization
at the top of read() may advance the input (i.e. in the case where there's
some garbage prior to the seek frame).

This factory was only needed in the past when we didn't have
AnalyticsCollector.setPlayer. Code becomes easier to use without this factory.

This new annotation declares everything as non-null by default and can be
used as a package annotation in package-info.java.
In this change the core lib offline package and the mediasession extension is
annotated that way as initial example usage.

DefaultMediaClock has currently two non-ideal behaviours:
1. One part of checking if it should use the renderer clock is checking whether
the associated renderer finished reading its stream. This only makes sense
if the renderer isn't already reading ahead into the next period. This can
be solved by forwarding if we are reading ahead to the sync command.
2. When switching from stand-alone to renderer clock we assume they are
exactly at the same position. This is true in theory, but in practise there
may be small differences due to the different natures of these clocks. To
prevent jumping backwards in time, we can temporarily stop the stand-alone
clock and only switch once the renderer clock reached the same position.
