Rename ipcall/socketcall specific defines to avoid conflict with

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Remove clause 3 and 4 from TNF licenses

Convert all the system call entry points from:
    int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

- sprinkle const.

First work on COMPAT_LINUX/amd64
Process startup and dynamiclinking work, but processes hang due to
Linux arch_prctl(2) not being really supported yet.

Fix the sync with head I botched.

improve the (#ifdef DEBUG_LINUX) socketcall argument dump code:
- print the socketcall type
- special case socket(2) call, it's also the only one with first argument
  not being a socket descriptor
- only dump the relevant part of linux_socketcall_dummy_args, instead
  of always the whole structure

make linux_socketcall_argsize[] static const

Do address family (AF_*) number translation for socket system calls which
pass socket address in our or out. This makes Linux programs using IPv6
working under emulation. This addresses kern/13279 by Jun-ichiro itojun Hagino.

Change sendmsg()/recvmsg() to expect the control information
to be passed the standard way (not 4.3BSD one, imlied by compat_43 code
or MSG_COMPAT). Linux uses different (arguably broken) CMSG_ALIGN() on some
architectures unfortunately, that would need to be handled eventually.

Also provide some other trivial stubs (like linux_sys_send()) to avoid
unneeded dependance on uipc_syscalls_43.c.

linux_sys_socketcall(): refuse negative 'what' values

Initial commit of scheduler activations and lightweight process support.

commit fix to PR7072: emulate linux non-blocking connect behavior more correctly

Assign my copyright to TNF. Merge with others were appropriate.
Regen syscall files after script change.

Attempt to fix the mess.

Split linux/compat/linux_socket.c into common and multi-architechture parts.  linux_socketcall.c contains the socketcall multiplexer.

Make this compile again, including Politically Correct const handling.

Prototyping changes.

Separate ioctl emulation by group.  Add (minimal) audio emulation.

Prefix names of system call implementation functions with `sys_'.

Make system calls conform to a standard prototype and bring those
prototypes into scope.

Rearrange #includes.

Use compat_util.[ch].

* Changed to use generic ELF code from kern/exec_elf.c (which was taken
  from the svr4 exec code plus the linux compat mods)
* Include file change
* Add multicast sockopts (from John Brezak)

Need netinet/tcp.h.

Convert TCP socket options.

Fill in `name' argument to getsockopt() correctly.

Fix typo.

Convert IP socket options.

Get rid of damned `static's.

Added Linux compat code.
