{set,fill}_{,fp,db}regs() fixup:
- Add dummy {set,fill}_dbregs() on architectures that don't have them.
- KSEfy the powerpc versions (struct proc -> struct thread).
- Some architectures had the prototypes in md_var.h, some in reg.h, and
some in both; for consistency, move them to reg.h on all platforms.
These functions aren't really MD (the implementation is MD, but the interface
is MI), so they should move to an MI header, but I haven't figured out which
one yet.
Run-tested on i386, build-tested on Alpha, untested on other platforms.

so that the T2 CSRs can be found on lynxes. Current should be
bootable on lynxes now.

Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested. Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.
This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().
It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".
broken and fixing it only creates a duplicate of what is already
in the FreeBSD kernel. Therefore, map the syscall directly to
getpgid().

While here, redefine the second entry for setpgid() so that we
don't need a stub. This is achieved by giving the second instance
the type NODEF.

macro. The commit log clearly states that the index given to the
macro is one higher than previously used to index the array. This
wasn't represented in the code and resulted in kernel page faults.
