24f9946db1 fix paul gardner's assert bug.
sometimes circuit_get_open_circ_or_launch() can return 0 but not
return a circuit, e.g. because too many circuits have failed recently
so the new one didn't launch. we need to tolerate that.

8b02610bd5 when an OR starts up, it loads its directory from cache.
then it serves *that directory* to others who ask for a copy of the
directory. it's better to serve no directory at all until you have a
fresh copy.

d381aa4696 Fix an evil bug: when we failed to write to our log, fputs()
gave us a sigpipe, and we logged that we were ignoring it,
causing us to fail to log that, and delete the log entry. Then
when the signal handler exited, we proceeded to delete the log
entry that had already been deleted.

Now we make sure to only log inside our signal handler if we'll
be exit()ing right after.

a2517b4f07 checking only 0.0.7 and 0.0.8 didn't work, because some dirservers
files have really old descriptors for the authdirservers, so we're
asking them in the new format because they're too old.

now we actually compare the version to a cutoff version, and act
appropriately.

also take this chance to use only >=0.0.8 servers for dns resolves,
because of the recent bugs. we'll bump to >=0.0.9pre1 once there are
some servers running that.
