2a28680d6e Disable assertion checking 
The trezor-crypto has some assertions, which are enabled unless
compiled with -DNDEBUG.  This does not make much sense for the Trezor
as could not write the assertion errors to stderr anyway.

This simple patch removes the dependency to assert, printf, etc. It
saves about 11kb flash and 2.2kb ram.

ed9d8c1ebb Fix RFC6979 generation of k. 
The standard says:
step h:
  Set T to the empty sequence.
  while tlen < qlen
    V = HMAC_K(V)
    T = T || V
  k = bits2int(T)

in this case (HMAC-SHA256, qlen=256bit) this simplifies to
  V = HMAC_K(V)
  T = V
  k = bits2int(T)
and T can be omitted.

The old code (wrong) did:
  T = HMAC_K(V)
  k = bits2int(T)
Note that V will only be used again if the first k is out of range.
Thus, the old code produced the right result with a very high probability.
