silent-rules is a new option with automake-1.11; older versions will
fatally exit with it. Using AM_SILENT_RULES will only result in a
warning at least through automake-1.9.

by packing the symbol map more efficiently.
This is mainly useful in making it harder to generate invalid bitstream:
before this change, one could code the same symbol twice. Now, it's
impossible, since we code the position using empty symbol slots, instead
of total position.
* Fix the HasOnlyLeftChild() naming while at it.

group like parameters together in prototypes, comments, move variable
declarations closer to first use.

_byteswap_ulong is defined in stdlib.h, release builds seem to pull it
in through a different path.

This allows managed code (e.g., C#) to free buffers returned by the API
instead of relying on free().
Based on suggestion from Steven (grokys at googlemail dot com).
Fixes issue #109.

- const / move declarations closer to first use
- remove unnecessary ()s
- don't return int unnecessarily with internal Init/Release
- compact some lines

- split the doc into sections for simple and extended format and move
example layouts to the end.
- use ASCII tables to describe chunk formats
- attempt to consistently use MUST/SHOULD, etc.
- remove bold from most terms, but add them to definition lists which
allow for the styling to be changed.

Enables --(enable|disable)-silent-rules and make V=[01] to control
compile output. Default is verbose as before.

A call to Append/Update would index the parts_ array w/-1 as num_parts_
had yet to be set by DecodePartition0. This would cause corruption
within the VP8Decoder member.
Fixes issue #106.

If the first call to WebPIUpdate contained all of partition 0, but not
enough to decode a macroblock the test for max macro block size could
fail (4096 bytes) due to a memory buffer offset not being updated.
This change offsets the buffer in the same manner as Append().
Fixes issue #105.

- remove some unused functions
- move global arrays from data to read only section
- explicitly cast malloc returns; not specifically necessary, but helps
show intent
- miscellaneous formatting

As with the loop filter, implementing this with intrinsics is difficult
because we require subscript access for reading and writing 32 bits at a
time.
Approximately 5% decode speed improvement. This could be increased by
exposing TransformOne and rewriting TransformTwo to only handle dual
IDCTs.

Add a dirty_ flag to keep track of updated probabilities and the need to
recompute the level costs.
This only makes a difference for "-m 2" method which was sub-optimal.
But it's overall cleaner to have this flag.

Add WebPDataCopy and use it in ReadImage which now returns WebPData*s.
Update ReadData prototype variables used with it to avoid unnecessary
const casting back and forth from void*.
