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.

split 7-byte stream_id string into 2-byte recognized and 2-byte stream_id
fix two seg faults in fetch_from_buf_http
fix several lurking seg faults in handling unexpected relay cells
still need to
* clean up relay_crypt
* use relay dummies if there's going to be a conflict with rh.recognized
* check for a conflict when generating stream_ids

never work.
fix vicious bug in choose_good_exit_server that caused it to *skip over*
pending circuits, and look only at *non-pending circuits*, when choosing
a good exit node for the new circuit.
bugfix: remove incorrect asserts in circuit_get_newest()
svn:r876
Increment failure counts only when circuits close without having been built.
Reset failure counts only on the second, and when circuits are done building.
svn:r847
bugfix: keep going when a circ fails in circuit_n_conn_open
(make circuit_enumerate_by_naddr_nport obsolete)
bugfix: make circuit_n_conn_open only look at circ's that start at us
bugfix: only try circuit_n_conn_open if we're an OP. Otherwise we
expect connections to always already be up.
bugfix: when choosing path length, pay attention to whether the directory
says a router is down.
bugfix: when picking good exit, skip routers which are known to be down
(more work needs to be done on this one)

- Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and bitcounts
18.0.0.0/8. Policies are parsed on startup, not when comparing to them.
- desired_path_len is now part of an opaque cpath_build_state_t structure.
- END_REASON_EXITPOLICY cells no longer include a port.
- RELAY_COMMAND_CONNECTED cells now include the IP address we've connected
to.
- connection_edge now has a client_dns cache to remember resolved addresses.
It gets populated by RELAY_COMMAND_CONNECTED cells and END_REASON_EXITPOLICY
cells. It gets used by connection_ap_handshake_send_begin. We don't
compare it to exit policies yet.
