Remove @dirrm entries from PLISTs

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Update to 5.7:

New features and improvements:

    * library
	  o new flavor of the ncurses library provides rudimentary
	  support for POSIX threads. Several functions are reentrant,
	  but most require either a window-level or screen-level
	  mutex.
	    (This is API-compatible, but not ABI-compatible with
	    the normal library).
	  o add NCURSES_OPAQUE symbol to curses.h, will use to make
	  structs opaque in selected configurations.
	  o add NCURSES_EXT_FUNCS and NCURSES_EXT_COLORS symbols
	  to curses.h to make it simpler to tell if the extended
	  functions and/or colors are declared.
          o add wresize to C++ binding
          o eliminate fixed-buffer vsprintf calls in C++ binding.
	  o add several functions to C++ binding which wrap C
	  functions that pass a WINDOW* parameter.
          o adapt mouse-handling code from menu library in form-library
          o improve tracing for form library, showing created forms, fields, etc.
          o make $NCURSES_NO_PADDING feature work for termcap interface .
	  o add check to trace-file open, if the given name is a
	  directory, add ".log" to the name and try again.
	  o several new manpages: curs_legacy.3x, curs_memleaks.3x,
	  curs_opaque.3x and curs_threads.3x
    * programs:
	  o modified three test-programs to demonstrate the threading
	  support in this version: ditto, rain, worm.
	  o several new test-programs: demo_panels, dots_mvcur,
	  inch_wide, inchs, key_name, key_names, savescreen,
	  savescreen.sh test_arrays, test_get_wstr, test_getstr,
	  test_instr, test_inwstr and test_opaque.
	  o add adacurses-config to the Ada95 install.
	  o modify tic -f option to format spaces as \s to prevent
	  them from being lost when that is read back in unformatted
	  strings.
	  o The tack program is now distributed separately from
	  ncurses.
    * terminal database
          o added entries:
                + Eterm-256color, Eterm-88color and rxvt-88color
                + aterm
                + konsole-256color
                + mrxvt
                + screen.mlterm
                + screen.rxvt
		+ teraterm4.59 is now the primary primary teraterm
		entry, renamed original to teraterm2.3
                + 9term terminal
                + Newbury Data entries
          o updated/improved entries:
                + gnome to version 2.22.3
                + h19, z100
                + konsole to version 1.6.6
                + mlterm, mlterm+pcfkeys
		+ xterm, and building-blocks for function-keys to
		xterm patch #230.

Major bug fixes:

    * add logic to tic for cancelling strings in user-defined
    capabilities (this is needed for current konsole terminfo
    entry).
    * modify mk-1st.awk so the generated makefile rules for linking
    or installing shared libraries do not first remove the library,
    in case it is in use, e.g., libncurses.so by /bin/sh.
    * correct check for notimeout in wgetch.
    * fix a sign-extension bug in infocmp's repair_acsc function.
    * change winnstr to stop at the end of the line.
    * make Ada95 demo_panels example work.
    * fix for adding a non-spacing character at the beginning of a line.
    * fill in extended-color pair to make colors work for
    wide-characters using extended-colors.
    * improve refresh of window on top of multi-column characters,
    taking into account split characters on left/right window
    boundaries.
    * modify win_wchnstr to ensure that only a base cell is returned
    for each multi-column character.
    * improve waddch and winsch handling of EILSEQ from mbrtowc by
    using unctrl to display illegal bytes rather than trying to
    append further bytes to make up a valid sequence.
    * restore curs_set state after endwin/refresh
    * modify keyname to use "^X" form only if meta has been called,
    or if keyname is called without initializing curses, e.g., via
    initscr or newterm.
    * modify unctrl to check codes in 128-255 range versus isprint.
    If they are not printable, and locale was set, use a "M-" or
    "~" sequence.
    * improve resizeterm by moving ripped-off lines, and repainting
    the soft-keys.
    * modify form library to accept control characters such as
    newline in set_field_buffer, which is compatible with Solaris.
    * use NCURSES_MOUSE_MASK in definition of BUTTON_RELEASE, etc.,
    to make those work properly with the --enable-ext-mouse
    configuration
    * correct some functions in Ada95 binding which were using
    return value from C where none was returned.
    * reviewed/fixed issues reported by Coverity and Klocwork tools.

Portability:

    * configure script:
          o new options:

	    --disable-big-strings
		control whether static string tables are generated
		as single large strings (to improve startup
		performance), or as array of individual strings.
            --disable-relink
		control whether shared libraries are relinked
		(during install) when rpath is enabled.
            --disable-tic-depends
		make explicit whether tic library depends on
		ncurses/ncursesw library.
            --enable-mixed-case
		override the configure script's check if the
		filesystem supports mixed-case filenames. This
		allows one to control how the terminal database
		maps to the filesystem. For filesystems that do
		not support mixed-case, the library uses generate
		2-character (hexadecimal) codes for the lower-level
		of the filesystem terminfo database
            --enable-reentrant
		builds a different flavor of the ncurses library
		(ncursest) which improves reentrant use of the
		library by reducing global and static variables
		(see the "--with-pthread" option for the threaded
		support).
            --enable-weak-symbols
		use weak-symbols for linking to the POSIX thread
		library, and use the same soname for the ncurses
		shared library as the normal library (caveat: the
		ABI is for the threaded library, which makes global
		data accessed via functions).
            --with-pthread
		build with the POSIX thread library (tested with
		AIX, GNU/Linux, FreeBSD, OpenBSD, HPUX, IRIX64,
		Solaris, Tru64).
            --with-ticlib
		build/install the tic-support functions in a separate
		library

          o improved options:

            --enable-ext-colors
                requires the wide-character configuration.
            --with-chtype
		ignore option value "unsigned" is always added to
		the type in curses.h; do the same for --with-mmask-t.
            --with-dmalloc
                build-fix for redefinition of strndup.
            --with-hashed-db
		    + accepts a parameter which is the install-prefix
		    of a given Berkeley Database.
		    + the $LIBS environment variable overrides the
		    search for the db library.
            --without-hashed-db
                assumed when "--disable-database" is used.

    * other configure/build issues:
          o build-fixes for LynxOS
          o modify shared-library rules to allow FreeBSD 3.x to use rpath.
          o build-fix for FreeBSD "contemporary" TTY interface.
          o build-fixes for AIX with libtool.
          o build-fixes for Darwin and libtool.
          o modify BeOS-specific ifdef's to build on Haiku.
	  o corrected gcc options for building shared libraries on
	  Solaris and IRIX64.
          o change shared-library configuration for OpenBSD, make rpath work.
          o build-fixes for using libutf8, e.g., on OpenBSD 3.7
	  o add "-e" option in ncurses/Makefile.in when generating
	  source-files to force earlier exit if the build environment
	  fails unexpectedly.
          o add support for shared libraries for QNX.
	  o change delimiter in MKlib_gen.sh from '%' to '@', to
	  avoid substitution by IBM xlc to '#' as part of its
	  extensions to digraphs.
    * library:
	  o rewrite wrapper for wcrtomb, making it work on Solaris.
	  This is used in the form library to determine the length
	  of the buffer needed by field_buffer.
	  o add/use configure script macro CF_SIG_ATOMIC_T, use
	  the corresponding type for data manipulated by signal
	  handlers.
	  o set locale in misc/ncurses-config.in since it uses a
	  range
	  o disable GPM mouse support when $TERM does not happen
	  to contain "linux", since Gpm_Open no longer limits its
	  assertion to terminals that it might handle, e.g., within
	  "screen" in xterm.
	  o reset mouse file-descriptor when unloading GPM library.
    * test programs:
	  o update test programs to build/work with various UNIX
	  curses for comparisons.
