some locking and rumpcopy primitives and refactor module building Makefiles
to work with both RUMP and kernel modules. This is first part of adding
support for regular test of zfs on NetBSD to hunt some bugs and make it
stable.
Ok by pooka@.
components which are too bloaty to be included in rumpkern (where
bloaty means "can be easily left out without anyone missing"), but
generally do not require the support of the dev/fs/net factions to
function. As the first one, add ksems. librumpcrypto will migrate
here too once I get my timeslice to deal with the setlists, as most
likely will tty support.
