9ffa96777e MFp4: portability work, general cleanup, locking fixes
change 38496
o add ipsec_osdep.h that holds os-specific definitions for portability
o s/KASSERT/IPSEC_ASSERT/ for portability
o s/SPLASSERT/IPSEC_SPLASSERT/ for portability
o remove function names from ASSERT strings since line#+file pinpints
  the location
o use __func__ uniformly to reduce string storage
o convert some random #ifdef DIAGNOSTIC code to assertions
o remove some debuggging assertions no longer needed

change 38498
o replace numerous bogus panic's with equally bogus assertions
  that at least go away on a production system

change 38502 + 38530
o change explicit mtx operations to #defines to simplify
  future changes to a different lock type

change 38531
o hookup ipv4 ctlinput paths to a noop routine; we should be
  handling path mtu changes at least
o correct potential null pointer deref in ipsec4_common_input_cb

chnage 38685
o fix locking for bundled SA's and for when key exchange is required

change 38770
o eliminate recursion on the SAHTREE lock

change 38804
o cleanup some types: long -> time_t
o remove refrence to dead #define

change 38805
o correct some types: long -> time_t
o add scan generation # to secpolicy to deal with locking issues

change 38806
o use LIST_FOREACH_SAFE instead of handrolled code
o change key_flush_spd to drop the sptree lock before purging
  an entry to avoid lock recursion and to avoid holding the lock
  over a long-running operation
o misc cleanups of tangled and twisty code

There is still much to do here but for now things look to be
working again.

88768458d2 "Fast IPsec": this is an experimental IPsec implementation that is derived
from the KAME IPsec implementation, but with heavy borrowing and influence
of openbsd.  A key feature of this implementation is that it uses the kernel
crypto framework to do all crypto work so when h/w crypto support is present
IPsec operation is automatically accelerated.  Otherwise the protocol
implementations are rather differet while the SADB and policy management
code is very similar to KAME (for the moment).

Note that this implementation is enabled with a FAST_IPSEC option.  With this
you get all protocols; i.e. there is no FAST_IPSEC_ESP option.

FAST_IPSEC and IPSEC are mutually exclusive; you cannot build both into a
single system.

This software is well tested with IPv4 but should be considered very
experimental (i.e. do not deploy in production environments).  This software
does NOT currently support IPv6.  In fact do not configure FAST_IPSEC and
INET6 in the same system.
