#25935: Allow DA address to be specified as FQDN

--------------------------------------+--------------------
It would be very helpful, particularly in sandbox situations, to specify
the Directory Authority by FQDN hostname instead of by IP address. This
would allow us to defer picking an actual IP address until the simulation
is started, and even to use some "in-game" DNS facility to figure out
the actual address after the simulation is launched.
Right now, specifying a FQDN for the "DirAuthority" config file entry
even *partially* works already: if the FQDN happens to start with a
digit, it is correctly resolved internally using available DNS resolver
infrastructure :)
The first attached patch makes that work in all cases (even when the
FQDN hostname does *not* begin with a digit).
The second attached patch allows FQDNs to be inserted into DA certs
created using tor-gencert, and correspondingly resolved when a client
parses the downloaded DA certificate.
I realize there is ongoing work to refactor parsing the DA config entry
(ticket #17224), so please consider this patch set either independently
on its own merits or as part of that larger effort. In the first case,
I'd be happy to redo and resubmit the patches based on review/feedback.
