* modules/pam_namespace/pam_namespace.c: New functions
unprotect_dirs(), cleanup_protect_data(), protect_mount(),
protect_dir() to protect directory by bind mount.
(cleanup_data): Renamed to cleanup_polydir_data().
(parse_create_params): Allow missing specification of mode
or owner.

directory. The directory is created when it doesn't exist.
(create_polydir): Protect and make the polydir by protect_dir(),
remove potential races.
(create_dirs): Renamed to create_instance(), remove call to
inst_init().
(ns_setup): Call protect_dir() on the polydir if it already exists.
Call inst_init() after the polydir is mounted.
(setup_namespace): Set the namespace protect data to be cleaned up
on pam_close_session()/pam_end().
(pam_sm_open_session): Initialize the protect_dirs.
(pam_sm_close_session): Cleanup namespace protect data.
* modules/pam_namespace/pam_namespace.h: Define struct for the
stack of protected dirs.
* modules/pam_namespace/pam_namespace.8.xml: Document when the
instance init script is called.
* modules/pam_namespace/namespace.conf.5.xml: Likewise.
