Previously we were using router_get_by_id(foo) to test "do we have a
descriptor that will let us make an anonymous circuit to foo". But
that isn't right for microdescs: we should have been using node_t.
Fixes bug 3601; bugfix on 0.2.3.1-alpha.

Previously, we had an issue where we'd treat an unknown address as
0, which turned into "0.0.0.0", which looked like a rejected
address. This meant in practice that as soon as we started doing
comparisons of unknown uint32 addresses to short policies, we'd get
'rejected' right away. Because of the circumstances under which
this would be called, it would only happen when we had local DNS
cached entries and we were looking to launch new circuits.

Requested by Gisle Vanem on tor-dev. I'm not quite sure this is the
right solution, but it's probably harmless.

It's possible for us to be a server and have a fingerprint without
having yet generated a descriptor.

Previously, we'd just take all the nodes in EntryNodes, see which
ones were already in the guard list, and add the ones that weren't.
There were some problems there, though:
* We'd add _every_ entry in EntryNodes, and add them in the order
they appeared in the routerlist. This wasn't a problem
until we added the ability to give country-code or IP-range
entries in the EntryNodes set, but now that we did, it is.
(Fix: We now shuffle the entry nodes before adding them; only
add up to 10*NumEntryGuards)
* We didn't screen EntryNodes for the Guard flag. That's okay
if the user has specified two or three entry nodes manually,
but if they have listed a whole subcontinent, we should
restrict ourselves to the entries that are currently guards.
(Fix: separate out the new guard from the new non-guard nodes,
and add the Guards first.)
* We'd prepend new EntryNodes _before_ the already configured
EntryNodes. This could lead to churn.
(Fix: don't prepend these.)
This patch also pre-screens EntryNodes entries for
reachableaddresses/excludenodes, even though we check for that
later. This is important now, since we cap the number of entries
we'll add.

This patch does NOTHING but:
- move code
- add declarations and includes as needed to make the new code
work
- declare the new functions.

Just looking at the "latest" consensus could give us a microdesc
consensus, if microdescs were enabled. That would make us decide
that every routerdesc was unlisted in the latest consensus and drop
them all: Ouch.

On IRC, wanoskarnet notes that if we ever do microdesc_free() on a
microdesc that's in the nodelist, we're in trouble. Also, we're in
trouble if we free one that's still in the microdesc_cache map.
This code adds a flag to microdesc_t to note where the microdesc is
referenced from, and checks those flags from microdesc_free(). I
don't believe we have any errors here now, but if we introduce some
later, let's log and recover from them rather than introducing
heisenbugs later on.
Addresses bug 3153.

The issue was that we overlooked the possibility of reverse DNS success
at the end of connection_ap_handshake_socks_resolved(). Issue discovered

For some inexplicable reason, Coverity departs from its usual
standards of avoiding false positives here, and warns about all
sscanf usage, even when the formatting strings are totally safe.
Addresses CID # 447, 446.

I'm not one to insist on C's miserly stack limits, but allocating a
256K array on the stack is too much even for me.

Using strncpy meant that if listenaddress were ever >=
sizeof(sockaddr_un.sun_path), we would fail to nul-terminate
sun_path. This isn't a big deal: we never read sun_path, and the
kernel is smart enough to reject the sockaddr_un if it isn't
nul-terminated. Nonetheless, it's a dumb failure mode. Instead, we
should reject addresses that don't fit in sockaddr_un.sun_path.
Coverity found this; it's CID 428. Bugfix on 0.2.0.3-alpha.

A couple of places in control.c were using connection_handle_write()
to flush important stuff (the response to a SIGNAL command, an
ERR-level status event) before Tor went down. But
connection_handle_write() isn't meaningful for bufferevents, so we'd
crash.
This patch adds a new connection_flush() that works for all connection
backends, and makes control.c use that instead.
Fix for bug 3367; bugfix on 0.2.3.1-alpha.

libnatpmp-20110618 changed the API that tor-fw-helper used and for a time
tor-fw-helper could not build against the newest libnatpmp. This patch brings
support for libnatpmp to tor-fw-helper.
