This is needed to upgrade the android_logger crate from 0.12.0
to 0.13.3.
with_max_level provides the same functionality as with_min_level.
The renaming is admittedly confusing, but the new name is accurate
and it makes sense that they deprecated and then removed the
previously poorly named with_min_level.
See crate documentation [1] and code [2].

These will soon be required by a lint.
Some functions were incorrectly marked as safe which were not actually
safe, so I've fixed those too.

* Add trait ClassPermission and fn check_permission. This binds
together permission names and their class name.
* Rename implement_permission! to implement_class!.
* Add #[selinux(class_name = <name>)] stanza to the syntax of
implement_class!.
Test: keystore2_test for regressions.

The run_as function allows a test with sufficient privileges to run a
closure as different identity given by a tuple of UID, GID, and SELinux
context. This is infrastructure in preparation for the keystore2 vts
test.

With these changes, the test easily identifies threading issues by
calling selinux concurrenly. With no locking in the selinux rust module,
this test causes hard locks very quickly (usually within 2 iterations).
Fixed test hangs (false positives) by adding an explicit "complete" to
all all threads instead of using the turnpike for both test start and
test complete.
Added some debug output and increased the iteration count to run the
test longer, getting more confidence in passing tests.
Lastly, use synthetically generated categories (CatCount) for all test
threads instead of just one thread. This seems to both make the test
more "abusive" of selinux as well as reduces test code size.

This test attempts to corrupt the access vector cache of libselinux by
calling selinux_check_access concurrently. The test will fail if the
cache gets corrupted in such a way that selinux_check_access ends up in
an infinite loop.

This patch revisits the Keystore 2.0 enforcements module to support
KM4.1 hardware enforced device locked keys.
* Consolidate the background handler into async_task.
* The auth token handler became AuthInfo and was moved into
enforcements.rs.
* The auth token validity check moved from database.rs to
enforcements.rs.

The list permission is special keystore2 permission that allows
callers to list arbitrary namespaces. It is not a key or namespace
specific permission.
Ignore-AOSP-First: This needs to land in googleplex first to updated
prebuilt vendor images. Otherwise it breaks
aosp-with-phone builds.

The libselinux wrapper provides a Context struct, that conveniently
wraps and owns a context string as returned by libselinux. However,
libbinder_rs provides a non owned string with a lifetime bounded
by the currently ongoing transaction. So instead of accepting
a reference to an owning Context, the check_access function in the
libselinux wrapper as well as the higher level permission function in
the permission module accept &CStr now which Context can also deref
into.
