Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
Changes 0.18.2:
* xgettext now understands the block comment syntax of Guile 2.0.
* libgettextpo library:
  - The initial msgstr of a new message is now "", not NULL.
  - Bug fixes in the functions po_message_is_range, po_file_check_all,
    po_message_check_all.
* Installation options:
  The configure options --with-xz and --with-bzip2 can be used to specify
  alternate compression methods for the archive used by the 'autopoint'
  program. These options, together with --with-git, allow to trade
  dependencies against installed package size. --with-xz has the highest
  compression rate, followed by --with-git, followed by --with-bzip2.
* Autoconf macros:
  - The autoconf macros installed by 'gettextize' now work with the
    forthcoming Automake 1.14 and require Autoconf version 2.60 or
    newer.
* Portability:
  - Building on MacOS X 10.7, Cygwin 1.7.10, and newer 64-bit mingw is
    now supported.

Log message:
Changes 0.18.1:
* msggrep: A '$' anchor in a regular expression now also matches the end of
  the string, even if it does not end in a newline.
* Dependencies:
  The libraries and programs are now linked with libunistring if this library
  is already installed.
* Installation options:
  The configure option --with-cvs is deprecated. The 'autopoint' program will
  now use the 'git' program by default to compress its archive. If the
  configure option --without-git is specified, 'autopoint' will not rely on
  'git', but will instead rely on a locally installed a 3 MB large archive.

Changes 0.18:
* Runtime behaviour:
  - On MacOS X and Windows systems, <libintl.h> now extends setlocale() and
    newlocale() so that their determination of the default locale considers
    the choice the user has made in the system control panels.
  - On MacOS X systems, the gettext()/dgettext()/... functions now respect the
    locale of the current thread, if a thread-specific locale has been set.
* PO file format:
  There is a new field 'Language' in the header entry.  It denotes the language
  code (plus optional country code) for the PO file.  This field can be used
  by automated tools, such as spell checkers.  It is expected to be more
  reliable than looking at the file name or at the 'Language-Team' field in
  the header entry.
  msgmerge, msgcat, msgen have a new option --lang that allows to specify
  this field.  Additionally, msgmerge fills in this new field by looking at
  the 'Language-Team' field (if the --lang option is not given).
* xgettext and PO file format:
  For messages with plural forms, programmers can inform the translators
  about the range of possible values of the numeric argument, like this:
    /* xgettext: range: 0..15 */
  This information 'range: 0..15' is stored in the PO file as a flag attached
  to the message.  Translators can produce better translations when they know
  that the numeric argument is small.
* Colorized PO files:
  msgattrib, msgcomm, msgconv, msgen, msgfilter, msggrep, msginit, msgmerge,
  msgunfmt, msguniq, xgettext now have options --color and --style, like msgcat
  has since version 0.17.
* msgmerge is up to 10 times faster when the PO and POT files are large.
  This speedup was contributed by Ralf Wildenhues.
* msgcmp has a new option -N/--no-fuzzy-matching, like msgmerge has since
  version 0.12.
* msgfilter now sets environment variables during the invocation of the
  filter, indicating the msgid and location of the messge being processed.
* xgettext now can extract plural forms from Qt 4 programs. The recommended
  xgettext command-line options for this case are:
    --qt --keyword=tr:1,1t --keyword=tr:1,2c,2t --keyword=tr:1,1,2c,3t
* xgettext --language=GCC-source now recognizes also the format strings
  used in the Fortran front-end of the GCC compiler, and marks them as
  'gfc-internal-format'.
* autopoint can now be used to update several PO directories all together.

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.

Add DESTDIR support.
