pyfec: rename pyfec to zfec
...
It turns out that "pyfec" turns off people who aren't Python hackers.
"allmyfec" is too long for a low-level core utility library.
"fec" is too generic (it is already used by Luigi Rizzo's library which this
library is based on, for one thing).
I'm open to other naming suggestions, especially before we widely announce this
library, which I expect will happen within a few days.

hash trees: further cleanup, to make sure we're validating the right thing

hashtree.py: improve the methods available for finding out which hash nodes

in the share hash tree, and stashing the thus-validated share hash for use
in the block hash tree.

unwrapped RIBucketReader references.
