c3ade864d9 fix PTRACE_PEEKUSER, PTRACE_POKEUSER, PTRACE_GETREGS. 
support PTRACE_SETREGS.
  In struct process, add 'unsigned long *ptrace_debugreg', instead of 'struct user *userp'.
  debug registers are read/written from/to ptrace_debugreg, save/restore in schedule().
  most general registers are proc->uctx.
  fs_base is proc->thread.tlsblock_base.
  gs_base,ds,es,fs,gs and orig_rax are uncompleted.
  other members in 'struct user' are ignored, same as Linux implementation.

19fa391d4f Implement vfork system call 
It's implemented by making it issue clone system call internally with
the arguments of (SIGCHLD, 0, 0, 0, 0). The feature in which the caller
of vfork blocks until the child issues exit/execve is not implemented.
Refer to #233.

3f13862a98 ptrace: add error stub to prevent mcexec from waiting 
In LTP's ptrace03 test,
there is a exit() preceded by ptrace(PTRACE_TRACEME).
In this case, processes will be usually finished immediately.
But mcexec will fall into waiting for parent's ptrace(PTRACE_CONT),
because mcexec sends itself a signal in processing of exit().
