new option: 'cwebp -mt ...'
new config flag: config.thread_level
(allowed thread_level are 0 or 1 for now. Maybe more later...)
If -mt is activated (and WEBP_USE_THREAD is used for compile), the alpha-compression
will be done in parallel to RGB coding for lossy. Can save quite a bit of latency...
Has no effect for lossless encoding.

This option remaps internal parameters to better match
the expected compression curve of JPEG and produce output files
of similar size, but with better quality.

It will decode to raw (flat) YUV format, similar to what
cwebp can take as input. Makes the PSNR/SSIM calculation easier.

This copies metadata selected by -metadata from the input to the output
if present.
Currently there is no WIC support for Windows builds.

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.

currently has no effect except to disable metadata extraction from the
input when the value is 'none'.

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.
quiets:
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.
