Harinarayanan K K d3e18f0c88 Reduced memory requirements. 
Buffer allocation is based on minimum level required for the
input resolution rather than the input max level.

Number of maximum context sets can be set to 1 to reduce
memory usage.

Added a macro ENC_MIN_PU_SIZE for minimum size of
inter prediction unit supported by encoder.

Changed the maximum constraint on number of MBs for NMB
processing to width in Mbs.
