Haiku port

[François Revol]

Hi,

I had a look at porting Twinkle to Haiku, and it seems ucommon is a
dependency.

I managed to build it on Haiku without too much trouble. See attached
patchset.

mlock: We currently don't have it. We have native calls alike so it
should be possible to add it someday.

libnetwork: the easiest way to hack it into was to fake it as libc (we
actually have libroot always linked in by default anyway which contains
libc).
Really, Those nested AC_CHECK_LIB should be replaced by AC_SEARCH_LIB.


Finally, our ifreq struct doesn't have named unions inside.

Things build but I didn't test anything yet.
