Log Message:
* Split sys/kern/sys_process.c into three parts:
        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.
