Robert Watson d903306a26 Enhance and expand kernel privilege regression tests in support of
work present in FreeBSD 7.0 to refine the kernel privilege model:

- Introduce support for jail as a testing variable, in order to
  confirm that privileges are properly restricted in the jail
  environment.

- Restructure overall testing approach so that privilege and jail
  conditions are set in the testing infrastructure before tests
  are invoked, and done so in a custom-created process to isolate
  the impact of tests from each other in a more consistent way.

- Tests now provide setup and cleanup hooks that occur before and
  after the test runs.

- New privilege tests are now present for several audit
  privileges, several credential management privileges, dmesg
  buffer reading privilege, and netinet raw socket creation.

- Other existing tests are restructured and generally improved as
  a result of better framework structure and jail as a variable.
  For exampe, we now test that certain sysctls are writable only
  outside jail, while others are writable within jail.  On a
  similar note, privileges relating to setting UFS file flags are
  now better exercised, as with the right to chmod and utimes
  files.
