1 - ptrace(2) syscall for native emulation
2 - common ptrace(2) syscall code (shared with compat_netbsd32)
3 - support routines that are shared with PROCFS and/or KTRACE
* Add module glue for #1 and #2. Both modules will be built-in to the
kernel if "options PTRACE" is included in the config file (this is
the default, defined in sys/conf/std).
* Mark the ptrace(2) syscall as modular in syscalls.master (generated
files will be committed shortly).
* Conditionalize all remaining portions of PTRACE code on a new kernel
option PTRACE_HOOKS.
XXX Instead of PROCFS depending on 'options PTRACE', we should probably
just add a procfs attribute to the sys/kern/sys_process.c file's
entry in files.kern, and add PROCFS to the "#if defineds" for
process_domem(). It's really confusing to have two different ways
of requiring this file.
