d2e90c7d09 capsicum_helpers: Add FIODTYPE to default ioctls allowed
FIODTYPE will be needed by hexdump(1) to speed up the -s flag on devices
that should be able to support fseek(3); specifically, in an attempt to
correct for the fact that most tape drives don't support seeking yet don't
indicate as such when fseeko(3) is invoked. Related: D10939

ada5397372 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.

db70589489 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.

e13d6f8b3f 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.

9fb85ece8b 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.

008d7c831f 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.

cf66982b37 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.
