b5a36cc9ad add -near_lossless [0..100] experimental option 
This compresses the uimage using lossless compression and controlable
decimating pre-process.
Code is under WEBP_EXPERIMENTAL_FEATURE while it's being experimented with.

fbda2f499c JPEG decoder: delay conversion to YUV to WebPEncode() call 
We store the raw RGB samples decoded from JPEG, and avoid precision loss.

Note that this may increase the encoding time reported by
cwebp -v, since RGB->YUV now occur during WebPEncode call
(in case of lossy), instead of ReadJPEG().
This also increases the memory use, since we're carying the
source ARGB samples around.

46fd44c104 thread: remove harmless race on status_ in End() 
if a thread was still doing work when End() was called there'd be a race
on worker->status_. in these cases, however, the specific value is
meaningless as it would be >= OK and the thread would have been shut
down properly, but we'll check 'impl_' instead to avoid any potential
TSan/DRD reports.

6422e683af VP8LFillBitWindow: enable fast path for 32-bit builds 
also reduce the load size from 64 to 32 bits as the top 32 bits are
being shifted away in the operation.

the change is neutral speed-wise on x86_64 as is the change in load size
on x86, but it gives a slight improvement on 32-bit arm.
x86 is improved ~13%, 32-bit arm ~3.7%
aarch64 is untested but will likely benefit as well.
