- Increment skippedBufferCount for VPX and ADTR.
- Set maxConsecutiveDroppedOutputBufferCount count for VPX.
Tweak its meaning to ignore skipped frames.
- Remove outputFormat/outputBuffer changed counts. These add
limited value. Also, MediaCodec is moving toward a model where
you don't see the output buffers changing because you dequeue
them one at a time (like how our extension decoders work).

1. Use ints rather than longs.
2. Remove some counters that dont seem hugely useful.
3. Replace use of volatile with explicit method calls that
cause a memory barrier. This is a lot more efficient than
using volatile because it can be invoked only once per
doSomeWork.
