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.

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.

the expression using dircount will be promoted to int when tdir_t is an
unsigned short.

warning: format specifies type 'unsigned short' but the argument has
type 'int' [-Wformat]

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.

* change some (*func_ptr) construct to func_ptr simply.
* remove one memcpy
* group #include related to decoding together

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

* fix gif2webp to handle disposal method and odd offset correctly
+ remove -scale and -crop option from vwebp, since it'll be broken
with offsets and fragments. Needs a revisit.
+ remove a warning in gif2web

Now, its: +duration+xoffset+yoffset+disposal
+disposal can be omitted and will default to +0 (NONE)
additionally, +xoffset+yoffset can be omitted and will default to +0+0

- Allow a duration of 0
- Rename LOOP chunk to ANIM and add the background color field to it.
- Add a disposal method field for each animation frame.
- Modify webpmux.c binary interface to allow the input of background color
and disposal methods. Also make '-loop' and '-bgcolor' arguments optional
with some default values.

- Also, use the term 'fragments' instead of 'tiling' in code
- This makes code consistent with the spec.

Use separate fourCCs "XMP " and "EXIF" instead of a common "META"
Also, some refactorization in webpmux.c

LSIM stands for "local similarity": before matching
a compressed pixel to the source, we search around in the source
and minimise the squared error. So, this is close to PSNR calculation,
but mitigates some of its limitations (pure translation and noise for instance).
There's a new -print_lsim option to cwebp too.

correct has_alpha check; previously it was controlled by keep_alpha,
which overrode the source format check.
