34519fcf41 Move the body of VLAN_INPUT_TAG() into a static inline function. 
(Maybe it shouldn't even be inline - but I'd have to work out where to put it).
VLAN_INPUT_TAG() now calls vlan_input_tag() and does '_errcase' when it fails.
In reality the callers should all be changed, _errcase is ALWAYS continue,
which used to 'continue' (ie break) the do .. while (0) loop - not the
intended action!
Found by ramming all the kernel sources through a modified lint and grepping
for a specific error.
While here enclose the body of VLAN_OUTPUT_TAG() in ().

d4ff34dc53 In tap_clone_destroy(), don't treat a pointer to the tap(4) softc 
like it is a device_t.

In tap_clone_creator(), set cf_fstate to FSTATE_FOUND instead of
_NOTFOUND to avoid a panic in config_detach() on a DIAGNOSTIC
kernel.  XXX I'm not sure that that is the right fix.

These changes should put a stop to the crash described in kern/38759.

5198e29b4c Make gre(4) work in the New File Descriptor / Socket Locking Order. 
Move the function+line printing into GRE_DPRINTF().

Retire gre_closef().  Retire gre_join().  Constify gre_reconf(),
and don't pass it an LWP any longer.

Make this work in the new file descriptor regime.  Add a kernel
thread per gre(4) instance whose purpose is to install the socket
into proc0's file descriptor table.  Add gre_fp_send() and
gre_fp_recv() for passing file_t pointers to proc0.

Fix locking:  don't solock() in the socket upcall, where it is
already held.  Do solock() before calling soconnect().

Simplify reconfiguration.

Update a comment that mentions finding a less specific route, since
we don't do that any more.

6d70f903e6 Network protocol interrupts can now block on locks, so merge the globals 
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.
