09daf1c828 Add support for audit pipe special devices, which allow user space
applications to insert a "tee" in the live audit event stream.  Records
are inserted into a per-clone queue so that user processes can pull
discreet records out of the queue.  Unlike delivery to disk, audit pipes
are "lossy", dropping records in low memory conditions or when the
process falls behind real-time events.  This mechanism is appropriate
for use by live monitoring systems, host-based intrusion detection, etc,
and avoids applications having to dig through active on-disk trails that
are owned by the audit daemon.

cba07e4acc Manage audit record memory with the slab allocator, turning
initialization routines into a ctor, tear-down to a dtor, cleaning
up, etc.  This will allow audit records to be allocated from
per-cpu caches.

On recent FreeBSD, dropping the audit_mtx around freeing to UMA is
no longer required (at one point it was possible to acquire Giant
on that path), so a mutex-free thread-local drain is no longer
required.

ea9f99ddcd - Call mii_phy_probe() after we allocated an ifp. mii has this evil
hack where it assumes the first field of the driver softc is the struct
ifnet, and it copies its value in mii_phy_probe().
- In the interrupt handler, set the mbuf m_len field on packet receive.

8917b8d28c - Always call exec_free_args() in kern_execve() instead of doing it in all
the callers if the exec either succeeds or fails early.
- Move the code to call exit1() if the exec fails after the vmspace is
  gone to the bottom of kern_execve() to cut down on some code duplication.

04f6d3effa - Add a ref count to the mount structure. Sleep for up to 3 seconds in
vfs_mount_destroy waiting for this ref to hit 0.  We don't print an
   error if we are rebooting as the root mount always retains some refernces
   by init proc.
 - Acquire a mnt ref for every vnode allocated to a mount point.  Drop this
   ref only once vdestroy() has been called and the mount has been freed.
 - No longer NULL the v_mount pointer in delmntque() so that we may release
   the ref after vgone() has been called.  This allows us to guarantee
   that the mount point structure will be valid until the last vnode has
   lost its last ref.
 - Fix a few places that rely on checking v_mount to detect recycling.

c983324ef5 Prefer AUE_FOO audit identifiers to AUE_O_FOO, which are largely left
over from the Darwin implementation.

When we implement a system call as a wrapper to sysctl(), audit it as
AUE_SYSCTL.  This leads to greater compatibility with Solaris audit
trails as sysctl() argument tokens are not the same as the ones for
the originaly system calls (i.e., setdomainname()).

Replace references to AUE_ events that are equivilent to AUE_NULL with
AUE_NULL.  In the case of process signal configuration, this is
because these events do not require auditing.

Move from the Darwin spelling of getsockopt() to the FreeBSD/Solaris
one.

89964dd284 When exiting a thread, submit any pending record. Today, we don't
audit thread exit, but should that happen, this will prevent
unhappiness, as the thread exit system call will never return, and
hence not commit the record.
