Those used to be normal to receive on hidden service circuits due to bug
1038, but the buggy Tor versions are long gone from the network so we
can afford to resume watching for them. Resolves the rest of bug 1038;
bugfix on 0.2.1.19.

Roger spotted this on tor-dev in his comments on proposal 221.

(Actually, detect DESTROY vs everything else, since arma likes
network timeout indicating failure but not overload indicating failure.)

This makes FastFirstHopPK an AUTOBOOL; makes the default "auto"; and
makes the behavior of "auto" be "look at the consensus."

This function is supposed to construct a list of all the ciphers in
the "v2 link protocol cipher list" that are supported by Tor's
openssl.  It does this by invoking ssl23_get_cipher_by_char on each
two-byte ciphersuite ID to see which ones give a match.  But when
ssl23_get_cipher_by_char cannot find a match for a two-byte SSL3/TLS
ciphersuite ID, it checks to see whether it has a match for a
three-byte SSL2 ciphersuite ID.  This was causing a read off the end
of the 'cipherid' array.

This was probably harmless in practice, but we shouldn't be having
any uninitialized reads.

(Using ssl23_get_cipher_by_char in this way is a kludge, but then
again the entire existence of the v2 link protocol is kind of a
kludge.  Once Tor 0.2.2 clients are all gone, we can drop this code
entirely.)

Found by starlight. Fix on 0.2.4.8-alpha. Fixes bug 12227.

Authorities now assign the Guard flag to the fastest 25% of the
network (it used to be the fastest 50%). Also raise the consensus
weight that guarantees the Guard flag from 250 to 2000. For the
current network, this results in about 1100 guards, down from 2500.
This step paves the way for moving the number of entry guards
down to 1 (proposal 236) while still providing reasonable expected
performance for most users.

Implements ticket 12690.

When specified, it overrides our default of 3 entry guards.

(By default, it overrides the number of directory guards too.)

Implements ticket 12688.
