De-duplicate references to current frame buffer

There are a number of explicit (as pointers) and implicit (as indices
into the reference buffer array) references to the current frame's
buffer.  This patch removes some of this redundancy, using the single
RefCntBuffer pointer cur_frame in AV1_COMMON.

This forms part of wider restructuring and refactoring in order to
achieve a clean API separation at the entry to the low-level encoder.
