Replace pid_t in autofs with struct pid reference
Make autofs container-friendly by caching struct pid reference rather than
pid_t and using pid_nr() to retreive a task's pid_t.
ChangeLog:
- Fix Eric Biederman's comments - Use find_get_pid() to hold a
reference to oz_pgrp and release while unmounting; separate out
changes to autofs and autofs4.
- Fix Cedric's comments: retain old prototype of parse_options()
and move necessary change to its caller.
