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.

Resolve some XXXX012 items:
   - Remove PathlenCoinWeight: if we want it again, we can add it
     back in.
   - Ditto with RelayBandwidth*.
   - Decide to leave in the "hey, you didn't set end_reason!" BUG log message,
     but stop telling people to bug me personally.
   - Postpone strengthening assert_connection_ok(): it's important, but 
     it's also a good way to introduce weird bugs.
   - Move some expensive consistency checking from dns_free_all() into
     assert_cache_ok().

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.

7239262f71 Don't tell anybody, but we're going OO here. This patch splits 
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.

87e3800dfc Finally solve the "closing wedged cpuworkers" bug. Woo. 
This happened when we got two create cells in a row from the same TLS
connection. It would hand one to the cpuworker, and then immediately
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.

Apparently in rare cases poll() is returning POLLIN for an idle

tries to send an answer to us.

c5bbb571d2 Refactor mark_for_close, connection_edge_end and friends. Now, everybody 
who wants to shut down a connection calls connection_mark_for_close instead
of setting marked_for_close to 1.  This automatically removes the connection
from the DNS cache if needed, sends a RELAY END cell if appropriate, and can
be changed to do whatever else is needed.

Still to do:
  - The same for circuits, maybe.
  - Add some kind of hold_connection_open_until_flushed flag, maybe.
  - Change stuff that closes connections with return -1 to use mark_for_close,
    maybe.
