7a01c3c3ec VP8LBitReader: fix remaining ubsan error with large shifts 
* make VP8LPrefetchBits() safe wrt past-EOS reads
* set 'BitReader::bits_" to a safe shifting value upon EOS

no visible performance difference on x86

7fe357b8c0 split 64-mult hashing into two 32-bit multiplies 
Speed-wise equivalent on x86 and ARM (maybe a tad faster, hard to tell).

Note that the two 32-bit multiples are not strictly equivalent
to the 64-bit one, since we're missing one carry propagation.
In practice, no observable difference was seen because of this
slightly different hashing result.

af74c1453b populate 'libwebpextras' with: import gray, rgb565 and rgb4444 functions 
update makefile.unix to provide 'make extras' building instructions.

note: input ordering depends on WEBP_SWAP_16BIT_CSP for rgb565 and rgb4444

d484555024 AnimEncoder API: Use timestamp instead of duration as input to Add(). 
When converting from video sources, the duration of current frame
is often unavailable until the next frame. So, we internally convert
timestamps to durations.
