Peter Wemm b0281cef04 Major fixes for ptrace()... 
PT_ATTACH/PT_DETACH implemented now and fully operational.
PT_{GET|SET}{REGS|FPREFS} implemented now, using code shared with procfs
PT_{READ|WRITE}_{I|D} now uses code shared with procfs
ptrace opcodes now fully permission checked, including ownerships.
doing an operation to the u-area on a swapped process should no longer
panic.
running gdb as root works for me now, where it didn't before.
general cleanup..

Note, that this has some tightening of permissions/access checks etc.
Some of these may be going too far..  In particular, the "owner" of the
traced process is enforced.  The process that created or attached to
the traced process is now the only one that can "do" things to it.
