76ec5fa1b6 cwebp: enable '-metadata'
This copies metadata selected by -metadata from the input to the output
if present.
Currently there is no WIC support for Windows builds.

0aeba52852 Provide an option to build decoder library.
When the config option '--enable-libwebpdecoder' is specified, the
lean decoder library 'libwebpdecoder' will be created in addition to
libwebp. Also dwebp binary will be linked to libwebpdecoder, if this
config option is specified.

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.

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.
