1.5x-2x faster encoding for method 3 and up

Browse Source 
using token-buffer (that is: slightly more memory. O(output_size))

This change is ON by default. To return to previous behaviour, use
'cwebp -low_memory' or set config.low_memory to true.

Side-effect of this new mode: it forces 1 partition only (which was
default anyway), and makes some statistics about the bitstream
no longer available. cwebp will no longer report 'intra4-coeffs', etc.

This mode also doesn't work (yet) with multi-pass, and -low_memory
is currently forced for multi-pass.

also: reversed the flag: USE_TOKEN_BUFFER -> DISABLE_TOKEN_BUFFER
also: fixed the kAverageBytesPerMB estimate
