0fe1c50e50 all: do standards compliant absdiff computation 
This resolves implementation defined behavior, and also silences -Wabsolute-value in clang 3.5+.
Moreover, the generated asm is identical to before modulo nop padding.

50833c9f7b Fix buffer_size argument to init_put_bits() in multiple encoders. 
Several encoders were multiplying the buffer size by 8, in order to get
a bit size. However, the buffer_size argument is for the byte size of
the buffer. We had experienced crashes encoding prores (Anatoliy) at
size 4096x4096.

124f0b2f46 flashsv2enc: only encode diff blocks when needed 
A flashsv2 block may have a "diff block" to indicate which scan lines of
the block are actually encoded.  However, this diff block need not be
used when the entire block is coded.
