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.
