7eaee9f1ac cwebp: add -metadata option
currently has no effect except to disable metadata extraction from the
input when the value is 'none'.

36c52c2cf1 tiffdec: use toff_t for exif ifd offset
versions < 4.0.0 used uint32 interchangeably, but with 4.0.0 toff_t
became 64-bit and TIFFTAG_EXIFIFD began returning it rather than
TIFF_LONG/uint32.

warning: format specifies type 'unsigned short' but the argument has

1f075f89b0 Lossless spec corrections/rewording/clarifications
- Correct BNF for 'predictor-image' and 'color image'
- Correct some references to 'br', 'VP8LReadBits' and 'ReadStream'
- Correct value ranges in distance mapping table.
- Rewrite section 4 (some rearrangement, rewording, adding context etc).
- Similarly, rewrite section 5.

d82a3e3391 More corrections/clarifications in lossless spec:
- 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.

bd0025579f cwebp/tiff: use the first image directory
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.

The main advantage is that you can avoid the use of uint64_t
