Getting active status of caching is needed to display on UI. Instead of a listener interface polling was chosen because of simplicity and better suits to UI refreshing.

CachingCounters.downloadedBytes was updated after whole data is downloaded. Now it's updated for each read into buffer. Buffer length defines how finer these updates are.

CachingCounters.totalBytes is added so UI can display a progress bar.

This change allows you to enable/disable tracks within which
all samples are key-frames without any re-buffering (e.g. audio,
text and metadata). This effectively reverts V2 back to the
behavior in V1, only this time we're doing it properly. []ly
disabling/enabling, or disabling/enabling whilst paused, no longer
cause samples to get "lost" between the source and renderers.

Note it also becomes really easy to support a few other things,
although support is not exposed in this change:

- Enable/disable video tracks without any re-buffering, by
  changing the toKeyframe argument passed to discardTo to true.
- Retain media in the buffer for some time after it's been played
  (e.g. to support a single back-5s-seek efficiently), by
  subtracting the desired back-buffer time from the value that's
  passed to discardTo.

- If we have <s1>garbage<s2> and discard <s2>, throw away
  the garbage too.
- Cleanup some documentation to consistently refer to the
  queue as "queue" rather than "buffer".

This will extend our CENC modes support to cbcs and cens. The change was
not split into two different CLs due to lack of test content for
default initialization vectors, aside from AES-CBCS encrypted ones.

This was broken prior to my recent changes, since
largestDequeuedTimestampUs was only being updated in readData.
It should have been updated in the skip methods. as well.

It's a bit messy at the moment with the deprecated methods
in there, but on the read side the new set of methods is as
follows:

Modifies the start of buffer:
- discardTo(time, keyframe, ...) [this is new]
- discardToRead()
- discardToEnd()

Modifies the read position:
- rewind()
- advanceTo(time, keyframe, ...) [this is a generalization of skipToKeyframeBefore]
- advanceToEnd() [previously called skipAll]
- read(...)

Which seems quite nice and self-consistent, and is powerful
enough for everything that we need to do as we move MediaSource
implementations over to the new methods.

TODOs for subsequent changes:
- Re-order methods in the two classes so that they're actually in
  the same order, and move the deprecated ones out of the way
- Enhance SampleQueueTest to also cover new functionality, as we
  start transitioning MediaSource implementations over to use it.

At the moment, only CENC-defined scheme types are known values.
This will allow having more information about the encryption
scheme through the format, which in turn will allow more informed
decisions on format support.
