Remove conditional logic from the parser and move it to its own class,
that way any improvements or conditional features will make cleaner
changes.

Add a flag that allows setting the error code AppArmor will send when
an operation is denied. This should not be used normally.

net_inet makes more sense since other finegrained network types can be
added in the future.

Extend the policy syntax to have a rule that allows specifying all
permissions for all rule types.
allow all,
This is useful for making blacklist based policy, but can also be
useful when combined with other rule prefixes, eg. to add audit
to all rules.

aa-load is a tool that loads cached (compiled) policies into
the kernel. It can receive as argument a file, a cache directory
containing the hash subtree, and a directory containing cached
files directly underneath - no hash.
This tool can be used in the as a guide for other init
systems to load the cached policies directly.

Setns is used to associate to an existing user namespace, so the
kernel security hook for user namespace creation is not called.
The restriction for setns is that it should have the capability
sys_admin.

This test uses unix_fd_server to open a file and pass
its file descriptor to the attach_disconnected tests, which
then mounts, pivots root and then tries to open the file.
Since the server execs the client, this commit also inverts the order
of the parameters to allow the server to forward the client's args
along with the unix_socket path.

The Hack used to build the libapparmor swig interface for ruby fails
with ruby 3.1. Instead of trying to do black magic in ruby to rename
the generated Makefile to Makefile.new, just save off the Makefile
and restore after ruby's setup has been called.

The auto-generated cap_names.h has problems when the parser if the
parser is built against a kernel with a smaller capability list than
the kernel policy is being compiled for.
Moving to a pre-generated list lets us support all capabilities even
when we build against older kernels. However we don't want to only use
the pre-generated list as that would make it too easy to miss when a
new capability has been added.
Keep auto generating the caps list and compare it to the pre-generated
caps list so we can detect when new capabilities are added, and fail
the build so that the pre-generated list can be updated. We screen the
diff for only additions so that the parser can continue to build on
older kernels that don't have the full capability list without errors.

The old patter *.* doesn't match lsb_release and nvidia_modprobe, and
the only file we ship in local is a README. This patch adjusts the
pattern to ignore everything except README.
Ignoring cscope.* files allows users of cscope to not be bothered by
`git status` reporting that an unknown file is in the source tree.
