Add encoder support for layers for RTC

Add some encoder controls needed for SVC encoding, and
some hooks needed for layered CBR rate control (to be implemented).

Add sample encoder for layered coding, for now only temporal layers
(1, 2, 3) are tested.

Use case for sample encoder is RTC(1 pass, real-time, zero-lag, CBR),
speed >= 7.

Example/extension for spatial layers will be done in separate CL.
