Add option to restrict filenames used VMS.
* src/options.h (enum restrict_files_os): Define "restrict_vms". * src/init.c (defaults) [__VMS]: Set "opt.restrict_files_os" to "restrict_vms". (cmd_spec_restrict_file_names): honor "vms". * src/url.c (filechr_not_unix): Define "filechr_not_vms". (filechr_table): Update for VMS. (append_uri_pathel): Honor opt.restrict_files_os. (FN_QUERY_SEP): Update for VMS. (FN_QUERY_SEP_STR): Update for VMS.
