[RFA/RFC] Replace call_ptrace and ptrace_wait in inf-ptrace.c

[Mark Kettenis <kettenis at gnu dot org>]

This is another step in the direction of eliminating the need for both
inf-ptrace.c and infptrace.c.  It eliminates the calls to call_ptrace
and ptrace_wait.

Andrew has recently suggested that we'd want debugging support for the
ptrace(2) interface, which could be implemented by using call_ptrace()
unconditionally.  That, however, is a bad idea, since this makes it
impossible for the compiler to properly typecheck the arguments to
ptrace().  Hence the removal of call_ptrace() usage.

In inf_ptrace_kill_inferior, I just replaced ptrace_wait() with
wait().  Calling target_post_wait here seems inappropriate.

If nobody objetcs, I'll check this in later this week.
