skal 1667bded67 Remove ReadOneBit() and ReadSymbolUnsafe()

Simplify and re-organize the VP8L bit-reader functions
(e.g.: the 40-bit look-ahead code was helping much)

Speed-up with LBITS=64, on arm7-a:

=> before:
./dwebp_justify_24_neon -v bryce_ll.webp
Time to decode picture: 11.393s
File bryce_ll.webp can be decoded (dimensions: 11158 x 2156).
...

=> after (LBITS=64):	Time to decode picture: 9.953s

making the VP8L bit-reader in 32 bit mode is going to be
harder (because we need to be able to read two symbols
at a time, each with max length 15 bits)
