When we used smartlist_free to free the list of succesful uploads
because we had succeeded in uploading everywhere, we did not actually
set the successful_uploads field to NULL, so later it would get freed
again in rend_service_descriptor_free. Fix for bug 948; bug
introduced in 0.2.1.6-alpha.

tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing. We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

It seems that 64-bit Sparc Solaris demands 64-bit-aligned access to
uint64_t, but does not 64-bit-align the stack-allocated char array we
use for cpuworker tags. So this patch adds a set/get_uint64 pair, and
uses them to access the conn_id field in the tag.

It turns out that we weren't updating the _ExcludeExitNodesUnion set's
country numbers when we reloaded (or first loaded!) the IP-to-country
file. Spotted by Lark. Bugfix on 0.2.1.6-alpha.

stream never finished making its connection, it would live
forever in circuit_wait state. Now we close it after SocksTimeout
seconds. Bugfix on 0.1.2.7-alpha; reported by Mike Perry.
svn:r18516
Previously, when we had the chosen_exit set but marked optional, and
we failed because we couldn't find an onion key for it, we'd just give
up on the circuit. But what we really want to do is try again, without
the forced exit node.
Spotted by rovv. Another case of bug 752. I think this might be
unreachable in our current code, but proposal 158 could change that.

This resolves bug 526, wherein we would crash if the following
events occurred in this order:
A: We're an OR, and one of our nameservers goes down.
B: We launch a probe to it to see if it's up again. (We do this hourly
in steady-state.)
C: Before the probe finishes, we reconfigure our nameservers,
usually because we got a SIGHUP and the resolve.conf file changed.
D: The probe reply comes back, or times out. (There is a five-second
window for this, after B has happens).
IOW, if one of our nameservers is down and our nameserver
configuration has changed, there were 5 seconds per hour where HUPing
the server was unsafe.
Bugfix on 0.1.2.1-alpha. Too obscure to backport.

This fixes the last known case of bug 891, which could happen if two
hosts, A and B, disagree about how long a circuit has been open,
because of clock drift of some kind. Host A would then mark the
connection as is_bad_for_new_circs when it got too old and open a new
connection. In between when B receives a NETINFO cell on the new
conn, and when B receives a conn cell on the new circuit, the new
circuit will seem worse to B than the old one, and so B will mark it
as is_bad_for_new_circs in the second or third loop of
connection_or_group_set_badness().
Bugfix on 0.1.1.13-alpha. Bug found by rovv.
Not a backport candidate: the bug is too obscure and the fix too tricky.

crypto_global_init gets called. Also have it be crypto_global_init
that calls crypto_seed_rng, so we are not dependent on OpenSSL's
RAND_poll in these fiddly cases.
Should fix bug 907. Bugfix on 0.0.9pre6. Backport candidate.
