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.

use buffers as generic "read" buffers instead of char buffers
This is a typing kludge -- if your buffers have elements of size > 1 then we will be processing only a subset of the elements and treating each byte of the element as a separate entry.
Oh well.

nicer API -- you don't have to shuffle the shares into place before calling decode_all()
Instead it does that shuffling in C inside fecmodule.
