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.

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).

Remove cn_lwp from struct componentname.  curlwp should be used

Remove some unused calls to stackgap_init()

Change the way that emulations locate files within the emulation root to
  avoid having to allocate space in the 'stackgap'
  - which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
  the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
  during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
  search for absolute pathnames in the emulation root, if that fails it will
  retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
  of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
  relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
  inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
  the real root is returned instead (matching the behaviour of emul_lookup,
  but being a cheap comparison here) so that programs that scan "../.."
  looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
  CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
  TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.

Pull up revision 1.7 (requested by junyoung in ticket #1488):
count executable image pages as executable for vm-usage purposes.
also, always do the VTEXT vs. v_writecount mutual exclusion
(which we previously skipped if the text or data segment was empty).

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

- Add a new vnode flag VEXECMAP, which indicates that a vnode has
  executable mappings.  Stop overloading VTEXT for this purpose (VTEXT
  also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
  mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
  than making a function call to do this (it no longer makes sense to
  use a function call, since we no longer overload VTEXT with VEXECMAP's
  meaning).
