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.

add some more data to be flushed but never turn POLLOUT on. not sure
how commonly this bug was hit, but it would be a doozy.
Also add some asserts to see if it happens elsewhere.

directory is the string that dirserv.c and directory.c deal with
routerlist is routerinfo's that are bundled together in routers.c
rename some of the get_routerlist functions to set_routerlist
preparing to break into router.c for stuff the router does,
and routerlist.c for handling routerlist.

Increment failure counts only when circuits close without having been built.
Reset failure counts only on the second, and when circuits are done building.

Move writing of pidfile after daemonizing, and also after setting the [ug]id:
This means that the tor user needs write priviliges to the pidfile location.
It needs it for unlinking the pidfile anyway.

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)

setuid, because after we setuid we don't have the priviledges we
need to setgid anymore, duh. merged switch_user() and
switch_group() into switch_id(), since that code has to be wound
together.
- return -1 from switch_id() if it's not defined to do anything else.
- moved daemoinize(), write_pidfile(), and switch_id() from main.c to
util.c

setuid and setgid respectively, and die if it can't.
(If the User option is set, tor will setgid to the user's gid as well.)
This happens after the pidfile is created, so that in cases where tor
needs to be root to work with the pidfile, it will at least be able to
create it, although it won't be able to delete it. That sucks, but
it's somewhat better than not being able to create the pidfile in the
first place.
