This patch changes the SELinux AVC to defer logging of paths to the audit
framework upon syscall exit, by saving a reference to the (dentry,vfsmount)
pair in an auxiliary audit item on the current audit context for processing
by audit_log_exit.

We turned this all off because the 'exe=' was causing deadlocks on
dcache_lock. There's no need to leave the pid and comm out though.
They'll all be logged correctly if full auditing is enabled, but we
should still print them in case auditing _isn't_ enabled.

This patch adds more messages types to the audit subsystem so that audit
analysis is quicker, intuitive, and more useful.

I forgot one type in the big patch. I need to add one for user space
originating SE Linux avc messages. This is used by dbus and nscd.

Add audit_log_type to allow callers to specify type and pid when logging.
Convert audit_log to wrapper around audit_log_type. Could have
converted all audit_log callers directly, but common case is default
of type AUDIT_KERNEL and pid 0. Update audit_log_start to take type
and pid values when creating a new audit_buffer. Move sequences that
did audit_log_start, audit_log_format, audit_set_type, audit_log_end,
to simply call audit_log_type directly. This obsoletes audit_set_type
and audit_set_pid, so remove them.

This fixes a deadlock on the dcache lock detected during testing at IBM
by moving the logging of the current executable information from the
SELinux avc_audit function to audit_log_exit (via an audit_log_task_info
helper) for processing upon syscall exit.
For consistency, the patch also removes the logging of other
task-related information from avc_audit, deferring handling to
audit_log_exit instead.
This allows simplification of the avc_audit code, allows the exe
information to be obtained more reliably, always includes the comm
information (useful for scripts), and avoids including bogus task
information for checks performed from irq or softirq.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
