9c25e9208a Port 'an' driver for Aironet PC4500/PC4800 IEEE802.11 card from FreeBSD. 
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
  functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.

Though I only have an Aironet card, Cisco card should be expected to work.

1ef2795be9 Separate the syscall handlers into two versions -- one which does ktrace, and 
one which doesn't.  Dynamically switch.
There's more to do on this, but I have to go to work.

f495cd9dc6 Introduce 2 new flags in types.h: 
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

66610a4779 Introduce PROC_PC(), which is used to get a process's user PC. If this is 
defined, call addupc_intr() directly from statclock() in the system time case,
using the same P_OWEUPC path if the copyin/copyout fails.
Use this in i386 to remove profiling code from the normal userret() path.

afc49e36eb Set md_regs before call the alternate syscall handler. 
Remove the EMUL_HAS_SYS___syscall test, because the handler is no longer shared

Rather than comparing with e_nsysent, just mask the value.  This is only done
to protect us from malicious programs anyway.

baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable: 
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

	sometimes works but not stable.

NOTE: installboot(8) still needs some hacking to DTRT, but at least this way
if you can load "/boot" off another partition (e.g, wd0h), then wd0a can be
of type `RAID' with a raidframe mirror at the start and the kernel
will load OK of wd0a, and with raidctl -A root partitions, it will change
root as well.
