Fixes bug 9337; bugfix on 0.2.4.7-alpha.

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.

Found by skruffy.

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.

Fix for #9254.  Bugfix on 0.2.4.14-alpha.

This is not actually a bug in the Tor code.

 Fix a bug in the voting algorithm that could yield incorrect results
 when a non-naming authority declared too many flags. Fixes bug 9200;
 bugfix on 0.2.0.3-alpha.

Found by coverity scan.

Ticket 9147.

(This caused a crash that was reported as bug 9122, but the underlying
behavior has been wrong for a while.)

Fix on 0.2.3.9-alpha.

Fixes bug 9090; bug not in any released Tor.

Conflicts:
	src/or/config.c
	src/or/relay.c

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.

Fixes bug 9002; bugfix on 0.1.1.11-alpha (which introduced guard
nodes), or on 0.0.6pre1 (which introduced hidden services).

Using "ours" strategy to avoid taking changes.

This fixes bug 9047 (and some parts of 9031, 8922, 8883 that weren't
fixed in 8822).  Bugfix on 0.2.2.6-alpha.

We can wait for 0.2.5 for a full rewrite.  #8964

doc/TODO and doc/spec/README were placeholders to tell people where to
look for the real TODO and README stuff -- we replaced them years ago,
though.

authority-policy, v3-authority-howto, and torel-design.txt belong in
torspec.  I'm putting them in attic there since I think they may be in
large part obsolete, but someone can rescue them if they're not.

translations.txt is outdated, and refers to lots of programs other
than Tor.  We have much better translation resources on the website
now.

tor-win32-mingw-creation.txt is pending review of a revised version
for 0.2.5 (see ticket #4520), but there's no reason to ship this one
while we're waiting for an accurate version.

the tor-rpm-creation.txt isn't obsolete AFAIK, but it belongs in
doc/contrib if anywhere.

Resolves bug #8965.

This is another fix to try to mitigate recurrences of 8031/8822.
