Commit summary:
---------------
2008-02-13  Tomas Mraz  <t8m@centrum.cz>

        * modules/pam_namespace/Makefile.am: Add argv_parse files and namespace.d
        dir.
        * modules/pam_namespace/argv_parse.c: New file.
        * modules/pam_namespace/argv_parse.h: New file.
        * modules/pam_namespace/namespace.conf.5.xml: Document new features.
        * modules/pam_namespace/pam_namespace.8.xml: Likewise.
        * modules/pam_namespace/pam_namespace.h: Use SECURECONF_DIR define.
        Define NAMESPACE_D_DIR and NAMESPACE_D_GLOB. Define new option flags
        and polydir flags.
        (polydir_s): Add rdir, replace exclusive with flags, add init_script,
        owner, group, and mode.
        (instance_data): Add ruser, gid, and ruid.
        * modules/pam_namespace/pam_namespace.c: Remove now unused copy_ent().
        (add_polydir_entry): Add the entry directly, no copy.
        (del_polydir): New function.
        (del_polydir_list): Call del_polydir().
        (expand_variables, parse_create_params, parse_iscript_params,
        parse_method): New functions.
        (process_line): Call expand_variables() on polydir and instance prefix.
        Call argv_parse() instead of strtok_r(). Allocate struct polydir_s on heap.
        (parse_config_file): Parse .conf files from namespace.d dir after
        namespace.conf.
        (form_context): Call getcon() or get_default_context_with_level() when
        appropriate flags are set.
        (poly_name): Handle shared polydir flag.
        (inst_init): Execute non-default init script when specified.
        (create_polydir): New function.
        (create_dirs): Remove the code which checks the polydir. Do not call
        inst_init() when noinit flag is set.
        (ns_setup): Check the polydir and eventually create it if the create flag
        is set.
        (setup_namespace): Use ruser uid from idata. Set the namespace polydir
        pam data only when namespace was set up correctly. Unmount polydir
        based on ruser.
        (get_user_data): New function.
        (pam_sm_open_session): Check for use_current_context and
        use_default_context options. Call get_user_data().
        (pam_sm_close_session): Call get_user_data().

+ * argv_parse.h --- header file for the argv parser.
+ *
+ * This file defines the interface for the functions argv_parse() and
+ * argv_free().
+ *
+ ***********************************************************************
+ * int argv_parse(char *in_buf, int *ret_argc, char ***ret_argv)
+ *
+ * This function takes as its first argument a string which it will
+ * parse into an argv argument vector, with each white-space separated
+ * word placed into its own slot in the argv.  This function handles
+ * double quotes and backslashes so that the parsed words can contain
+ * special characters.   The count of the number words found in the
+ * parsed string, as well as the argument vector, are returned into
+ * ret_argc and ret_argv, respectively.
+ ***********************************************************************
+ * extern void argv_free(char **argv);
+ *
+ * This function frees the argument vector created by argv_parse().
