Patch from Robert Hogan: Generate STREAM NEW events for dnsport requests and tunneled directory connections.  Log when we are testing for hijacking.

Sun CC likes to give warnings for the do { } while(0) construction for making statement-like macros.  Define STMT_BEGIN/STMT_END macros that do the right thing, and use them everywhere.

Patch from Tup: treat RESOLVED_TYPE_ERROR_TRANSIENT as a SERVERFAILED, and RESOLVED_TYPE_ERROR as NOTEXIST.  Generate transient/nontransient errors more sensibly.  Set flags better on DNS replies.

Fix handling of resolves with very long or otherwise malformed addresses, and comment dns_resolve better, and stop making what should be a BUG warning into an assert(0).  This fixes bug 427, which was introduced around 9900/9931/9932.  Not a backport candidate: 0.1.2.x never had this bug.

Fix a longstanding dnsworker-related bug: when we decide to kill a DNS worker for having been in use too long, and we independently decide to close one of the exit connections waiting for that DNS worker (perhaps because we got an END relay cell), it was possible for us to try to double-free the connection.  We were smart enough to detect this and assert, but not smart enough to fix this bug before now.  This should resolve bug 390.  Backport candidate.

   - Postpone strengthening assert_connection_ok(): it's important, but 
     it's also a good way to introduce weird bugs.

Instead of just checking known-invalid addresses for DNS hijacking, we
 now check randomly generated addresses, and if too many of them map to
 the same IP, we assume that IP is the destination of a DNS hijack
 attempt.
 
 A little bird tells me that some DNS hijackers think that declining to
 give an A record for RFC2606 addresses (like .invalid and .example)
 makes them more standards compliant.  Standardswise, this is like an
 illicit brothel making sure that nobody has pulled the tags off the
 mattresss, but that doesn't get us out of working around it.

circuit_t into origin_circuit_t and or_circuit_t.  I fixed some
segaults; there may be more.  We still need to move more rendezvous
stuff into subtypes.

This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.

Also, this discards the old HALF_OPEN code, which nobody seems to
want.

This happened when we got two create cells in a row from the same TLS

handle the second one -- after it had registered that the first one was
busy, but before it had updated the timestamp that we use to decide how
*long* it's been busy.
