940cef3367 Make bridges send AUTH_CHALLENGE cells 
The spec requires them to do so, and not doing so creates a situation
where they can't send-test because relays won't extend to them because
of the other part of bug 9546.

Fixes bug 9546; bugfix on 0.2.3.6-alpha.

0daa26a473 Send NETINFO on receiving a NETINFO if we have not yet sent one. 
(Backport to Tor 0.2.3)

Relays previously, when initiating a connection, would only send a
NETINFO after sending an AUTHENTICATE.  But bridges, when receiving a
connection, would never send AUTH_CHALLENGE.  So relays wouldn't
AUTHENTICATE, and wouldn't NETINFO, and then bridges would be
surprised to be receiving CREATE cells on a non-open circuit.

Fixes bug 9546.

d5cfbf96a2 Fix an uninitialized-read when parsing v3 introduction requests. 
Fortunately, later checks mean that uninitialized data can't get sent
to the network by this bug.  Unfortunately, reading uninitialized heap
*can* (in some cases, with some allocators) cause a crash if you get
unlucky and go off the end of a page.

Found by asn.  Bugfix on 0.2.4.1-alpha.

1d2e8020b7 Fix bug9309, and n_noncanonical count/continue code 
When we moved channel_matches_target_addr_for_extend() into a separate
function, its sense was inverted from what one might expect, and we
didn't have a ! in one place where we should have.

e9c2484311 Fix for bug 9295: Don't crash when running --hash-password. 
Fix on 0.2.4.15-rc; I'm doing this branch against 0.2.3, since we're
considering #9122 for an 0.2.3 backport, and if we do, we should merge
this too.

2e1fe1fcf9 Implement a real OOM-killer for too-long circuit queues. 
This implements "algorithm 1" from my discussion of bug #9072: on OOM,
find the circuits with the longest queues, and kill them.  It's also a
fix for #9063 -- without the side-effects of bug #9072.

The memory bounds aren't perfect here, and you need to be sure to
allow some slack for the rest of Tor's usage.

This isn't a perfect fix; the rest of the solutions I describe on
codeable.
