METADATA_ICCP was renamed to METADATA_ICC in
d8dc72a examples: normalize icc related program arguments
but was merged without rebasing after
0bc4268 cwebp: output metadata statistics

Reported to eventually be 4% on ARM
(see https://code.google.com/p/webp/issues/detail?id=134 for details)
We might activate it selectively later...
Output values is not bitwise the same as the LUT-based
version, but difference is only +/-1 at max.

older versions of automake (1.9) it seems would install the headers
regardless of the fact that the library was marked noinst_
this change follows some of the header guidance found here:

EXPERIMENTAL -> WEBP_EXPERIMENTAL_FEATURES
the former is not used in the source; this adds
WEBP_EXPERIMENTAL_FEATURES to config.h

this allows DLLs to be built under mingw and sets up a more obvious
dependency in the shared objects

expands to e.g., -lpthread/-pthread, etc. if --enable-threading is used
and additional libs/flags are required

This is required for WebP lossy+Alpha images, where Alpha channel is taking
60-70% of the compression (CPU) cycles.
Also evaluated on 1000 PNG corpus and overall compression speed
is 15-40% better for lossy (PNG+Alpha) compression.
The pure lossless compression numbers are almost same (or little
better) with this change.

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

When a ANMF/FRGM chunk size (read from file) is smaller than ANMF/FRGM header
size (which is constant and implicit), the parser should report an error.
