6a1c4d1efc capsicum_helpers: Add LOOKUP flag
Add a helper routine for opening a directory that is restricted to being
used for opening relative files as stdio streams.

I think this will really help basic adaptation of multi-file programs to
Capsicum. Rather than having each program initialize a rights object and
ioctl/fcntl arrays for their root fd for relative opens, consolidate in the
logical place.

103701b155 capsicum_helpers: Squash errors from closed fds
Squash EBADF from closed stdin, stdout, or stderr in caph_limit_stdio().
Any program used during special shell scripts may commonly be forked
from a parent process with closed standard stream.  Do the common sense
thing for this common use.

7b3ea376a2 META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

4232f82668 Enforce overwritting SHLIBDIR
Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.

This makes /lib being populated again.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

bd1da0a002 Approved, oprócz użycie RESTORE_ERRNO() do ustawiania errno.
Change the nvlist_recv() function to take additional argument that
specifies flags expected on the received nvlist. Receiving a nvlist with
different set of flags than the ones we expect might lead to undefined
behaviour, which might be potentially dangerous.

Update consumers of this and related functions and update the tests.

Approved by:	pjd (mentor)

Update man page for nvlist_unpack, nvlist_recv, nvlist_xfer, cap_recv_nvlist
and cap_xfer_nvlist.
