b4f30afe3d 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.

833ef86a88 update interfaces and docs for codec
It now takes a sequence of buffers instead of a single string for both encode and decode, and it also takes a separate sequence of shareids for decode instead of a sequence of tuples, and it returns a sequence of buffers instead of a single string.

06835e5a2b 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.
