Rom Lemarchand 2f34c5033e logwrap: Change semantics of NULL status in android_fork_execvp
When passing a NULL status to android_fork_execvp the return
status will now be the return value of the child if it exited
properly, otherwise a non-0 value will be returned.

- Wait for the child to exit before propagating SIGINT and SIGQUIT

- Add ignore_int_quit argument to logwrap() that gives the caller the
option to ignore SIGINT and SIGQUIT while logwrap is running

Rom Lemarchand b58a822955 logwrapper: prevent logwrap from hanging when child dies
Sometimes the read on the PTY can wait indefinitely if the child
dies. By using a poll statement that monitors both the output
of the child and its state we prevent this from happening.
