Robert Watson 37bde6c0a3 Introduce support for Mandatory Access Control and extensible
kernel access control.

Restructure the vn_open_cred() access control checks to invoke
the MAC entry point for open authorization.  Note that MAC can
reject open requests where existing DAC code skips the open
authorization check due to O_CREAT.  However, the failure mode
here is the same as other failure modes following creation,
wherein an empty file may be left behind.
