1c0e87f6d8 Add a pointless 2-byte memset in cell_pack
There is probably no code that can write the 2 bytes at the end of the
packed_cell_t when the cell is only a 512-byte cell, but let's not get
overconfident there.

11c467f643 Fix a stupid logic-error in warnings about low ports.
Instead of warning about low ports that are advertised, we should have
been warning about low ports that we're listening on.  Bug 7285, fix
on 0.2.3.9-alpha.

05194cce62 Avoid c99 designated initializers in circuitmux_ewma.c
We still want to build on compilers w/o c99 support, such as
(notoriously, shamefully) MSVC.

So I'm commenting out the designated initializers in
circuitmux_ewma.c.  The alternative would have been to use some kind
of macros to use designated initializers only when they're
supported, but that's error-prone, and can lead to code having
different meanings under different compilers.

Bug 7286; fix on 0.2.4.4-alpha; spotted by Gisle Vanem.

c442d85439 Fix a remotely triggerable assertion failure (CVE-2012-2250)
If we completed the handshake for the v2 link protocol but wound up
negotiating the wong protocol version, we'd become so confused about
what part of the handshake we were in that we'd promptly die with an
assertion.

This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha.
All servers running that version or later should really upgrade.

Bug and fix from "some guy from France."  I tweaked his code slightly
to make it log the IP of the offending node, and to forward-port it to
0.2.4.

85659d3964 Fix parse_short_policy (bug 7192.)
Our implementation of parse_short_policy was screwed up: it would
ignore the last character of every short policy.  Obviously, that's
broken.

This patch fixes the busted behavior, and adds a bunch of unit tests
to make sure the rest of that function is okay.

Fixes bug 7192; fix on 0.2.3.1-alpha.

Conflicts:
	src/or/circuitbuild.c

There was a huge-looking conflict in circuitbuild.c, but the only
change that had been made to circuitbuild.c since I forked off the
split_circuitbuild branch was 17442560c4.  So I took the
split_circuitbuild version of the conflicting part, and manually
re-applied the change from 17442560c44e8093f9a..

26946c659b Restore the 'address' value of tunneled connections
When we merged the channel code, we made the 'address' field of linked
directory connections created with begindir (and their associated edge
connections) contain an address:port string, when they should only
have contained the address part.

This patch also tweaks the interface to the get_descr method of
channels so that it takes a set of flags rather than a single flag.

field of an exit connection used in making a tunneled directory
request.  Turns out that wasn't right.
