sha3: optimizations and cleanup ( #41 )
...
* complate reset of the SHA-3 code. Affects mostly the code in sha3.go
* fixes a bug which causes SHAKE implementation to crash
* implementation of Read()/Write() avoid unnecessary buffering as much
as possible
* NOTE: at some point I've done separated implementation for SumXXX,
functions, but after optimizing implementation of Read/Write/Sum, the
gain wasn't that big

SHAKE: Don't use function pointers ( #20 )
...
* xorIn and copyOut function pointers cause input and output data
to be moved to heap. This degrades performance of calling code.
* This change removes usage of those function pointers. We will always
use unaligned implementation as it's faster (but may crash on some
systems)
* Benchmark compares generic vs unaligned xorIn and copyOut
