RGB to YUV conversion was not using SSE to finish up the row.
End data is now copied to a buffer big enough to fit in a
SSE register.
(UPSAMPLE_LAST_BLOCK was already using that trick).

if a single text file name is supplied as argument
(e.g.: 'webpmux my_long_list_of_frames.txt'), the command
line arguments are actually parsed from this file.
Tokenizer will remove space, tabs, LF, CR, returns, etc.
+ changed ImgIoUtilReadFile() to return a null-terminated
data, for convenience.
+ misc clean-up in the code

Change-Id: Id1b03256c4c04b8db31527e60cd31dd20ce6f3ad
- 11/24/2017: version 0.6.1
This is a binary compatible release.
* lossless performance and compression improvements + a new 'cruncher' mode
(-m 6 -q 100)
* ARM performance improvements with clang (15-20% w/ndk r15c, issue #339)
* webp-js: emscripten/webassembly based javascript decoder
* miscellaneous bug & build fixes (issue #329, #332, #343, #353, #360, #361,
#363)
Tool updates / additions:
added webpinfo - prints file format information (issue #330)
gif2webp - loop behavior modified to match Chrome M63+ (crbug.com/649264);
'-loop_compatibility' can be used for the old behavior

this results in flickering with animated webp + alpha. disabling the
option is a workaround to restore the behavior to the previous release.

remove auto-filter (-af) support and make WebPPictureCopy,
WebPPictureIsView, WebPPictureView, WebPPictureCrop, and
WebPPictureRescale noops.

with gcc-4.8, clang-4.0.1/5 this is no faster (actually up to 2x slower)
than the code generated for memset (0x01010... * dst[-1]). shuffles in
sse4 recover a bit, but performance is still down.
Change-Id: Ie85e8353f8ede559d0b05a1d388787fd18ecc80f
Rewrote WebPPictureHasTransparency() to use them (even for argb).
This is 10% faster, for some reasons.
SSE2 version should be straightforward.
Removes a TODO.

The WebPDemux and WebPAnimDecoder APIs are provided for the purpose of
animated webp parsing and decoding. No major changes are currently
planned for the libwebp API.
