into modules. By and large this commit:
- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
netbsd32_lwp.c, and remove remaining traces of SA.
This still needs some MD (and possibly MI, depending on the chosen
solution) changes to actually work.
- Remove useless (thanks to COMPAT_XX behaviour) #ifdefs in
syscalls.master
- Make netbsd32_compat_43.c compiled per COMPAT_LINUX32 because the latter
needs stuff from it.
Fixes Perry's PR#34951.
code.
- To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to
kevent1 that points to functions that do the actual copyin/copyout
operations. This is similar to what was done in FreeBSD by Paul Saab.
- Add the COMPAT_NETBSD32 definitions and hooks.

o Move the statfs family out of netbsd32_fs.c and netbsd32_netbsd.c to
netbsd_compat_20.c, compiled with COMPAT_20

- delete ktrsyscall32()
- add a check #ifdef _LP64 to do the conversion if P_32 is set to the
standard ktrsyscall()
- add a couple of similar _LP64/P_32 checks to the systrace code.
this should get systrace working for 32 bit apps as well as complete
ktrace support for "trace_enter/trace_exit" using platforms such as amd64.
XXX: systrace isn't supported on sparc64 currently... (it doesn't use
trace_enter/trace_exit, or have it's own calls to systrace_xxx()...)
the main purpose of this function is to adjust the "argsize" value of
the ktrace syscall record, otherwise userland will see N/2 (rounded
down) arguments instead of N.
