Usher pattern matching (was Re: [Monotone-devel] Usher crashes)

OK, I'll compile the problems I found before:

It won't work.

It works, but only if I fix line 185 of server_manager::connect_to_server
where it  matches pattern against host:

if (!srv && !pattern.empty() && !by_pattern.empty())
    {
      i = by_pattern.lower_bound(pattern);
      if (i != by_pattern.end() && i->first == prefix(host))
                                                      ^^^^

And even if I try to make it match against pattern, it fails,
because of the way operator== works for struct prefix. Is this
intentional? Shouldn't it also do partial matches?
