the expression using dircount will be promoted to int when tdir_t is an
unsigned short.
quiets:
warning: format specifies type 'unsigned short' but the argument has
type 'int' [-Wformat]

- Rectify a few BNF descriptions
- Corrections in "Decoding Flow of Image Data" section:
1. The sequence in case of "S < 256" should be green, red, blue, alpha.
2. In case of "S >= 256 + 24", the index should be "S - (256 + 24)".
- Provide more description to clarify "Decoding Flow of Image Data" section.
- Some cosmetics: use '1's instead of '1, 2, 3...' sequence, as kramdown takes
care of sequencing.

tiffdec does not support and warns about multi-directory images.
previously, the code would read all the directories and thus attempt to
use the last rather than the first as the message suggests.

- precompute filtering strength once for all at the beginning
instead of per-macroblock
- reduce size of VP8MB struct from 8 bytes to 4.
- removed VP8StoreBlock() accordingly

unused currently, but the intent is to allow each format to populate
exif/xmp/icc with cwebp then transferring it to the webp file.

The color transform block size is stored as 3 bits, not 4.
Fixed the description. The code snippet is already correct.

GetCoeffs is (by far) the most consuming function of the decoder.
No speed change (unfortunately), but the main loop is somehow clearer.

* treat the last coeff as a special case

The main advantage is that you can avoid the use of uint64_t
some times, sticking to 32bit only.
Default still is BITS=32, this is mainly "in case".

The binaries should have dependency on related libraries only.
For example, 'vwebp' sould not depend on libpng, libjpeg etc.

+ remove -scale and -crop option from vwebp, since it'll be broken
with offsets and fragments. Needs a revisit.
