The iint cache stores whether the file is measured, appraised, audited
etc. This patch moves the IMA_AUDITED flag into the per-namespace
ns_status, enabling IMA audit mechanism to audit the same file each time
it is accessed in a new namespace.

The ns_status is not looked up if the CONFIG_IMA_NS is disabled or if
any of the IMA_NS_STATUS_ACTIONS (currently only IMA_AUDIT) is not
enabled.

^none of the ... are enabled.

Read and write operations on the iint flags is replaced with function
calls. For reading, iint_flags() returns the bitwise AND of iint->flags
and ns_status->flags. The ns_status flags are masked with
IMA_NS_STATUS_FLAGS (currently only IMA_AUDITED). Similarly
set_iint_flags() only writes the masked portion to the ns_status flags,
while the iint flags is set as before. The ns_status parameter added to
ima_audit_measurement() is used with the above functions to query and
set the ns_status flags.
