Matt Mackall e68e5b664e random: make mixing interface byte-oriented 
Switch add_entropy_words to a byte-oriented interface, eliminating numerous
casts and byte/word size rounding issues.  This also reduces the overall
bit/byte/word confusion in this code.

We now mix a byte at a time into the word-based pool.  This takes four times
as many iterations, but should be negligible compared to hashing overhead.
This also increases our pool churn, which adds some depth against some
theoretical failure modes.

The function name is changed to emphasize pool mixing and deemphasize entropy
(the samples mixed in may not contain any).  extract is added to the core
function to make it clear that it extracts from the pool.
