Convert all the system call entry points from:

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.

ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...

Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).

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.

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

In preparation for COMPAT_NETBSD32 on SH-5:

- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
instead of using u_int32_t everywhere,
- The MD netbsd32_machdep.h header now

In preparation for COMPAT_NETBSD32 on SH-5:

- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
instead of using u_int32_t everywhere,
- The MD netbsd32_machdep.h header now defines a macro (at least on
current implementations) which converts a 32-bit pointer to its 64-bit
equivalent,
- Change the MI code to utilise the above two items in all the right places,
- Implement netbsd32___sigaction_sigtramp().

Tested on Sparc64 by Matt Green.

add RCSIDs (including regeneration of files as appropriate)

fix typo - it should be compat_09_netbsd32_uname, not compat_09_netbsd32_ouname

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

Add netbsd32_compat_14.c

Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly
names like compat_14_compat_netbsd32_sys_shmctl().

SPARC32->NETBSD32

move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)

add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.
