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.

4a22046c86 squash! Add crypto_pk_check_key_public_exponent function 
Rename crypto_pk_check_key_public_exponent to crypto_pk_public_exponent_ok:
it's nice to name predicates s.t. you can tell how to interpret true
and false.

Our regular DH parameters that we use for circuit and rendezvous
crypto are unchanged.  This is yet another small step on the path of
protocol fingerprinting resistance.

70abd843fd crypto_cipher_set_key cannot fail 
In 5e4d53d535 we made it so that
crypto_cipher_set_key cannot fail. The call will now
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.

3b2fc659a8 Refactor consensus signature storage for multiple digests and flavors. 
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>.

f6dbe5a0d4 Refactor crypto error handling to be more like TLS error handling: 
crypto_perror is a no-no, since an operation can set more than one
error.

Also, fix a bug in the unix crypto_seed_rng: mixing stdio with
/dev/urandom is a bad idea, since fopen can make all kinds of weird
extraneous syscalls (mmap, fcntl, stat64, etc.) and since fread tends
to buffer data in big chunks, thus depleting the entropy pool.

3d4ccb781a Refactor buffers; implement descriptors. 
'buf_t' is now an opaque type defined in buffers.c .

Router descriptors now include all keys; routers generate keys as
needed on startup (in a newly defined "data directory"), and generate
their own descriptors.  Descriptors are now self-signed.

Implementation is not complete: descriptors are never published; and
upon receiving a descriptor, the directory doesn't do anything with
it.

At least "routers.or" and orkeygen are now obsolete, BTW.

f12fdd62aa Be smarter about getting key matter from DH. 
Formerly, once we had g^xy, we took the last N bytes from g^xy.

Now, we take SHA(g^xy || [0]) || SHA1(g^xy || [1]) || ... , in order
to use all bits from g^xy equally, and generate as much key material
as we need.

253f0f160e laying the groundwork for dynamic router lists 
revamped the router reading section

reference counting for crypto pk env's (so we can dup them)

we now read and write pem pk keys from string rather than from FILE*,
  in anticipation of fetching directories over a socket
  (so now on startup we slurp in the whole file, then parse it as a string)

fixed a bug in the proxy side, where you could get some circuits
  wedged if they showed up while the connection was being made
