Initial import of libgfshare-1.0.5, a library which implements Shamir's
Secret Sharing Scheme, into the packages collection.

	In simple terms, this package provides a library for implementing the
	sharing of secrets and two tools for simple use-cases of the
	algorithm.  The library implements what is known as Shamir's method
	for secret sharing in the Galois Field 2^8.  In slightly simpler words,
	this is N-of-M secret-sharing byte-by-byte.  Essentially this allows
	us to split a secret S into any M shares S1..SM such that any N of
	those shares can be used to reconstruct S but any less than N shares
	yields no information whatsoever.
