66157b3899 Fix 'ugidfw remove' after r284251 incorrectly changed it.
The sysctl_rule() node removes entries when given a newptr and newlen == 0.

bf41706273 Set some internal helpers as static and initialize few variables to silence
CLANG WARNINGS.
BUMP SHLIB_MAJOR version as the ABI potentially changed.

Also run an 'exp run' to double check if any external project are using
those functions. Thanks antoine@.

89ddbd45e5 Add some new options to mac_bsdestended. We can now match on:
subject: ranges of uid, ranges of gid, jail id
	objects: ranges of uid, ranges of gid, filesystem,
		object is suid, object is sgid, object matches subject uid/gid
		object type

We can also negate individual conditions. The ruleset language is
a superset of the previous language, so old rules should continue
to work.

These changes require a change to the API between libugidfw and the
mac_bsdextended module. Add a version number, so we can tell if
we're running mismatched versions.

Update man pages to reflect changes, add extra test cases to
test_ugidfw.c and add a shell script that checks that the the
module seems to do what we expect.

a6c2bc8bcb When parsing the second {uid,gid} in an identity phrase for ugidfw,
check the password or group database before attempting to parse as an
integer, as is done for the first {uid,gid} in an identity phrase.

47ab23aa82 Add bsde_add_rule(), which is similar to bsde_set_rule() except that
the caller does not specify the rule number -- instead, the kernel
module is probed for the next available rule, which is then used.

46d1a925c2 Introduce support for Mandatory Access Control and extensible
kernel access control.

Provide a library to manage user file system firewall-like rules
supported by the mac_bsdextended.ko security model.  The kernel
module exports the current rule set using sysctl, and this
library provides a front end that includes support for retrieving
and setting rules, as well as printing and parsing them.

Note: as with other userland components, this is a WIP.  However,
when used in combination with the soon-to-be-committed ugidfw,
it can actually be quite useful in multi-user environments to
allow the administrator to limit inter-user file operations without
resorting to heavier weight labeled security policies.
