Use _XOPEN_SOURCE instead of _POSIX_C_SOURCE
...
It seems this is required to get all the IPv6 definitions, though most
systems aren't very picky. NetBSD seems to be one of those picky
systems, though.

Greatly simplify a bunch of things
...
1. If sockets are non-blocking, no need to use poll() on them. Just try
to write regardless and ignore the outcome. This means we don't need the
pollvec stuff anymore.
2. getline(3) is apparently still too new to POSIX that it's hard to use
portably. We don't really need it that badly anyway.
3. Don't use MSG_DONTWAIT. It's non-standard and apparently still hard
to use portably. Set sockets to non-blocking instead.
4. Since we're not polling on client sockets, the queue is a whole lot
simpler.

Improve support for Solaris and its derivatives
...
Requires extensions to be enabled due to incomplete support for
POSIX.1-2008. However one of the now-exposed extensions is tragically
named "struct queue". This struct was been renamed to "struct fifo".
Thanks to @yvoinov for reporting this issue and collaborating on a
solution.
Closes #14 , #17 .

This is necessary for supporting OmniOS (Solaris), which doesn't
actually document how to actually define this flag. This platform also
requires LDLIBS='-lsocket -lnsl' when compiling.
