Problem: no permission to relicense tweetnacl integration

Solution: remove implementation. Frank Hartmann <soundart@gmx.net>,
the author, rejected our request to relicense under MPL2, so we
have to remove his copyrighted work.
Tweetnacl is not security-supported and could not be used in
production environments anyway, the supported backend is libsodium.

-//  When different threads have their own context the file descriptor
-//  variable is shared and is subject to race conditions in tweetnacl,
-//  that lead to file descriptors leaks. In long-running programs with
-//  ephemeral threads this is a problem as it accumulates.
-//  thread-local storage cannot be used to initialise the file descriptor
-//  as it is perfectly legal to share a context among many threads, each
-//  of which might call curve APIs.
-//  Also libsodium documentation specifically states that sodium_init
-//  must not be called concurrently from multiple threads, for the
-//  same reason. Inspecting the code also reveals that the close API is
-//  not thread safe.
-//  The context class cannot be used with static variables as the curve
-//  utility APIs like zmq_curve_keypair also call into the crypto
-//  library.
-//  The safest solution for all use cases therefore is to have a
-//  static lock to serialize calls into an initialiser and a finaliser,
-//  using refcounts to make sure that a thread does not close the library
-//  while another is still using it. To avoid the static initialization
-//  order fiasco, this is done using function-local statics, if the
-//  compiler implementation supports thread-safe initialization of those.
-//  Otherwise, we fall back to global statics.
-//  HOWEVER, this initialisation code imposes ordering constraints, which
-//  are not obvious to users of libzmq, and may lead to problems if atexit
-//  or similar methods are used for cleanup.
-//  In that case, a strict ordering is imposed whereas the contexts MUST
-//  be initialised BEFORE registering the cleanup with atexit. CZMQ is an
-//  example. Hence we make the choice to restrict this global transition
-//  mechanism ONLY to Tweenacl + *NIX (when using /dev/urandom) as it is
-//  the less risky option.
