Let PF_KEY socks hold their own lock instead of softnet_lock

Operations on SAD and SPD are executed via PF_KEY socks. The operations
include deletions of SAs and SPs that will use synchronization mechanisms
such as pserialize_perform to wait for references to SAs and SPs to be
released. It is known that using such mechanisms with holding softnet_lock
causes a dead lock. We should avoid the situation.

branches: 1.9.2;
Tweak header file inclusions

Eliminate struct protosw::pr_output.

You can't use this unless you know what it is a priori: the formal
prototype is variadic, and the different instances (e.g., ip_output,
route_output) have different real prototypes.

Convert the only user of it, raw_send in net/raw_cb.c, to take an
explicit callback argument. Convert the only instances of it,
route_output and key_output, to such explicit callbacks for raw_send.
Use assertions to make sure the conversion to explicit callbacks is
warranted.

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

Initial import of Sam Leffler's `Fast-IPsec' from FreeBSD 4.
Fast-IPsec is a rework of the OpenBSD and KAME IPsec code, using the
OpenCryptoFramework (and thus hardware crypto accelerators) and
numerous detailed performance improvements.

This import is (aside from SPL-level names) the FreeBSD source,
imported ``as-is'' as a historical snapshot, for future maintenance
and comparison against the FreeBSD source. For now, several minor
kernel-API differences are hidden by macros a shim file, ipsec_osdep.h,
which (aside from SPL names) can be targeted at either NetBSD or FreeBSD.
