70d08f764d Explicit length checks in create_rend_cpath(). 
Had to also edit hs_ntor_circuit_key_expansion() to make it happen.

ba928e1ac8 Refactor the HS ntor key expansion to fit the e2e circuit API. 
We want to use the circuit_init_cpath_crypto() function to setup our
cpath, and that function accepts a key array as input. So let's make our
HS ntor key expansion function also return a key array as output,
instead of a struct.

Also, we actually don't need KH from the key expansion, so the key
expansion output can be one DIGEST256_LEN shorter. See here for more
