Log Message:
Add support for PTRACE_VFORK_DONE and stub for PTRACE_VFORK in ptrace(2)
PTRACE_VFORK is supposed to be used to track vfork(2)-like events, when
parent gives birth to new process child and stops till it exits or calls
exec().
Currently PTRACE_VFORK is a stub.
PTRACE_VFORK_DONE is notification to notify a debugger that a parent has
resumed after vfork(2)-like action.
PTRACE_VFORK_DONE throws SIGTRAP with TRAP_CHLD.
