- 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.

(Fixing GitHub issue #2923)

Cuurently, ClippingMediaSource issues an initial discontinuity. This causes the
renderers to be disabled and re-enabled when this media source is used in a sequence
with other sources (or in a loop).

This change disables the use of an initial discontinuity for audio-only media under
the assumption that audio streams have random access capabilities.

Allows to call assertReleased() on that class.

Previously, writeAllocationNode was not advanced to the
terminating node when finishing writing sample data that
fills exactly up to the end of the current write node.
This wasn't actually broken, but is confusing because it
causes edge cases where the start/read references could
temporarily refer the node after the current write node.
This change advances the write reference in this case,
removing this confusion and bringing the implementation
in line with what the design doc says happens.

Also making some simplification and consistency changes.
