libsodium: Added libsodium 0.4.2 - A portable, cross-compilable, installable, packageable fork of NaCl

Note:

We need to inject '-std=c99' because the reference implementation of blake2
is using C99 specific semantics.

+[I] A portable, cross-compilable, installable, packageable fork of NaCl
+
+[T] NaCl (pronounced "salt") is a new easy-to-use high-speed software library
+[T] for network communication, encryption, decryption, signatures, etc.
+[T] NaCl's goal is to provide all of the core operations needed to build
+[T] higher-level cryptographic tools.  Sodium is a portable, cross-compilable,
+[T] installable, packageable fork of NaCl, with a compatible API.
