The tor_memcmp code is by Robert Ransom, and the tor_memeq code is
by me.  Both incorporate some ideas from DJB's stuff.

tor_fragile_assert() might be a no-op, so we have to return something
here to indicate failure to the caller.

If the user sent a SIGNAL NEWNYM command after we fetched a rendezvous
descriptor, while we were building the introduction-point circuit, we
would give up entirely on trying to connect to the hidden service.

Original patch by rransom slightly edited to go into 0.2.1

i.e. without closing the AP connection.

None of the comparisons were _broken_ previously, but avoiding
signed/unsigned comparisons makes everybody happier.

Fixes bug2475.

Under heavy load, this could result in an assertion failure.  Fix for
bug 2933; bugfix on 0.2.0.10-alpha.

Issue noticed by Steven Murdoch; fixes bug 2689. The cast didn't do
anything, and we don't need to look at the return value of the function
here.

Partial backport of daa0326a .
Resolves bug 2402.  Bugfix on 0.2.1.15 (for the part where we switched to
git) and on 0.2.1.30 (for the part where we dumped micro-revisions.)

This reverts commit a1073ee9.

Apparently, we totally misunderstood how the debian packages were using
microrevisions.  Better fix that!

This is based on shitlei's fix for bug2629, with extra parens removed.
Fixes bug 2629, bugfix on 0.2.1.2-alpha.

We need to _REJECT_ descriptors with accept6/reject6 lines.  If we
let them onto the network , other un-upgraded tors will crash.

This reverts commit b3918b3b.

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.

Our regular DH parameters that we use for circuit and rendezvous
crypto are unchanged.  This is yet another small step on the path of
protocol fingerprinting resistance.

(Backport from 0.2.2's 5ed73e38)

Fixes #2408.
