1d18c2deb6 Don't shadow parameters with local variables
This is a little error-prone when the local has a different type
from the parameter, and is very error-prone with both have the same
type.  Let's not do this.

Fixes CID #437,438,439,440,441.

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.

0fd3ad75da Report wrong key sizes correctly
When we introduced NEED_KEY_1024 in routerparse.c back in
0.2.0.1-alpha, I forgot to add a *8 when logging the length of a
bad-length key.

Bugfix for 3318 on 0.2.0.1-alpha.

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.

b95dd03e5f Log descriptions of nodes, not just nicknames.
This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.

There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address.  I might have missed a couple more too.

This is a fix for bug 3045.

59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

4cc348e896 Code to make clients fetch and use microdescriptors for circuit building
To turn this on, set UseMicrodescriptors to "1" (or "auto" if you
want it on-if-you're-a-client).  It should go auto-by-default once
0.2.3.1-alpha is released.

Because of our node logic, directory caches will never use
microdescriptors when they have the right routerinfo available.

b3918b3bbb Disallow reject6 and accept6 lines in descriptors
This fixes a remotely triggerable assert on directory authorities, who
don't handle descriptors with ipv6 contents well yet. We will want to
revert this once we're ready to handle ipv6.

Issue raised by lorth on #tor, who wasn't able to use Tor anymore.
Analyzed with help from Christian Fromme. Fix suggested by arma. Bugfix
on 0.2.1.3-alpha.
