e908e3a332 Merge remote-tracking branch 'origin/maint-0.2.1' into maint-0.2.2 
Fixed trivial conflict due to headers moving into their own .h files
from or.h.

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.

50c259d763 Make the DH parameter we use for TLS match the one from Apache's mod_ssl 
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.

115782bdbe Fix a heap overflow found by debuger, and make it harder to make that mistake again 
Our public key functions assumed that they were always writing into a
large enough buffer.  In one case, they weren't.

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>.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version. 
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.
