CacheEvictor.onStartFile currently receives a length, which is the
maximum size of the content that might be written. The LRU cache
evictor will make sure there's sufficient space for the specified
size. If the actual size of the content is unknown, CacheDataSink
passes maxCacheFileSize.
The current behavior isn't ideal. It seems valid for a developer to
specify maxCacheFileSize=Long.MAX_VALUE if they don't want any
file fragmentation in the cache. However if they then attempt to
cache something with unknown length, LRU cache will try and make
room for content of length Long.MAX_VALUE, and end up evicting the
entire cache to do so.
This change alters the logic so a length is only passed if the
actual size of the content is known. In other cases C.LENGTH_UNSET
is now passed. The LRU evictor will not evict until after the file
is committed. Note a custom LRU evictor could still opt to evict to
ensure some application specified amount of space, if that's the
desired behavior.

When a Download is created it's set to queued state but doesn't notify
listeners about this state. DownloadManager checks if it can start the
download. After this checks it notifies the listeners.
With this change Download can immediately check if it can be started and
sends correct notification.

Problem: There is nothing in the Cache interface that enforces that
these methods are implemented by reading/writing content metadata,
however our own code (CacheDataSource) relies on this property since
it mixes use of [get|set]ContentLength and use of metadata. Using
metadata is the right approach because it minimizes the number of
index writes (e.g. it allows the redirect URI and the content length
to be committed by a single write).
Solution: Remove [get|set]ContentLength, which are redundant anyway,
and use metadata everywhere. Also expose the keys being used through
the public API; there's no particular reason why they shouldn't be.
We previously had an API for getting and setting content length, but
no API for getting and setting redirect uri.

This adds the basic track selection capabilties (including tests).
The new capabilities are not exposed yet through the DownloadHelper implementations
and there will also be more helper methods (e.g. to select multiple audio lanuages at
once).

We currently have two factory methods where it is completely unclear which one needs
to be overridden.
This change deprecates the old one, adds a Util method to easily map back from the new
to the old behaviour, and updates all implementations of the now deprecated method in
our code.

[Problem]
As the alignment of each lineas are calculated individually, the
artificially introduced CENTER and RIGHT alignments can be mixed
with each other and with the default LEFT alignment. The mixed results
look worse than just using the original DEFAULT, and the readability
is radically decreased.
[Solution]
Pre-calculate the alignment for each line, and use the leftmost of them
for all lines. The intention of caption provider could be different, but
the worst case scenario is that we revert back everything to LEFT
alignment that is the only option in the CEA608 standard so we
show everything at the exact location it is set in the content.
The readability is never worse than the one given by the content
provider.
[Test]
This should influence CEA608 pop-up cations only. (Not roll up).
Test various live channels with this change.
Note: Beginning of commercials tend to have PAINT-ON mode as that
is immediately showing incoming characters, not just at the end
of the line like POP-on mode.
