all includes that now are included due to implicit pollution via if_var.h

- Depend on opt_ddb.h, since npcb_dump() is ifdef'd DDB.
- Include ddb/ddb.h so we can call db_printf() and use DB_SHOW_COMMAND().
- Don't test results of malloc() under DIAGNOSTIC, let the memory allocator
take care of its own invariants.

- Introduce a subsystem mutex, natm_mtx, manipulated with accessor macros
NATM_LOCK_INIT(), NATM_LOCK(), NATM_UNLOCK(), NATM_LOCK_ASSERT(). It
protects the consistency of pcb-related data structures. Finer grained
locking is possible, but should be done in the context of specific
measurements (as very little work is done in netnatm -- most is in the
ATM device driver or socket layer, so there's probably not much
contention).
- Remove GIANT_REQUIRED, mark as NETISR_MPSAFE, remove
NET_NEEDS_GIANT("netnatm").
- Conditionally acquire Giant when entering network interfaces for
ifp->if_ioctl() using IFF_LOCKGIANT(ifp)/IFF_UNLOCKGIANT(ifp) in order
to coexist with non-MPSAFE atm ifnet drivers..
- De-spl.

function prototypes. Use LIST_FOREACH instead of explicit loops.
The indentation of functions indendet by 4 space have been left alone.
2-space indented functions have been re-indented.
Distribute all but the most fundamental malloc types. This time I also
remembered the trick to making things static: Put "static" in front of
them.
