de0dca0de7 Refactor the API for setting up a block cipher.
It allows us more flexibility on the backend if the user needs to
specify the key and IV at setup time.

bbf2fee8ff Reject 128-byte keys that are not 1024-bit
When we added the check for key size, we required that the keys be
128 bytes.  But RSA_size (which defers to BN_num_bytes) will return
128 for keys of length 1017..1024.  This patch adds a new
crypto_pk_num_bits() that returns the actual number of significant
bits in the modulus, and uses that to enforce key sizes.

Also, credit the original bug3318 in the changes file.

always succeed, to returning a boolean for success/failure makes
no sense.

d2b4b49ff0 Reduce log level for someone else sending us weak DH keys.
See task 1114. The most plausible explanation for someone sending us weak
DH keys is that they experiment with their Tor code or implement a new Tor
client. Usually, we don't care about such events, especially not on warn
level. If we really care about someone not following the Tor protocol, we
can set ProtocolWarnings to 1.

This patch introduces a new type called document_signature_t to represent the
signature of a consensus document.  Now, each consensus document can have up
to one document signature per voter per digest algorithm.  Also, each
detached-signatures document can have up to one signature per <voter,
algorithm, flavor>.
