Subject: Multiple changes to ACodec/codec tools:

Make sure sf2 does not coalesce input buffers, generalize ACodec's codec
instantiation based on OMXCodec's list of eligible component names.

Some changes/additions to the "sf2" commandline tool

Make surface options consistent with stagefright tool, i.e. use '-S' instead of '-s'
New option '-R' renders surface-allocated buffers.

Also fixes a longstanding bug introduced when generalizing from surfaces to native windows that never used surface-allocated buffers in sf2 even when the option was specified.
