Recursive bump for graphics/freetype2 buildlink addition.

Add missing archivers/bzip2 buildlink

Bump PKGREVISION

freetype2's .pc file requests linkage with -lz, so pull in zlib's bl3.mk

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.

Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.

Over 1200 files touched but no revisions bumped :)

RECOMMENDED is removed. It becomes ABI_DEPENDS.

BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.

BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.

BUILDLINK_DEPENDS does not change.

IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".

Added to obsolete.mk checking for IGNORE_RECOMMENDED.

I did not manually go through and fix any aesthetic tab/spacing issues.

I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.

I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.

As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.

As discussed on tech-pkg.

I will commit to revbump, pkglint, pkg_install, createbuildlink separately.

Note that if you use wip, it will fail!  I will commit to pkgsrc-wip
later (within day).

Recursive revision bump / recommended bump for gettext ABI change.

Fixed pkglint warnings. The warnings are mostly quoting issues, for
example MAKE_ENV+=FOO=${BAR} is changed to MAKE_ENV+=FOO=${BAR:Q}. Some
other changes are outlined in

    http://mail-index.netbsd.org/tech-pkg/2005/12/02/0034.html

Libtool fix for PR pkg/26633, and other issues.  Update libtool to 1.5.10
in the process.  (More information on tech-pkg.)

Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.

Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.

Depend on freetype2>=2.1.8, since dependent packages have been adapted to
the new version.

Split out the code that deals with checking whether the software is
built-in or not into a separate builtin.mk file.  The code to deal
checking for built-in software is much simpler to deal with in pkgsrc.

The buildlink3.mk file for a package will be of the usual format
regardless of the package, which makes it simpler for packagers to
update a package.

The builtin.mk file for a package must define a single yes/no variable
USE_BUILTIN.<pkg> that is used by bsd.buildlink3.mk to decide whether
to use the built-in software or to use the pkgsrc software.

Use tab instead of spaces for indentation to make pkglint happy.

Reorder some lines so that BUILDLINK_USE_BUILTIN.<pkg> set in the
environment overrides all other settings.

Create a new variable PREFER_NATIVE that has the opposite semantics
as PREFER_PKGSRC.  Preferences are determined by the most specific
instance of the package in either PREFER_PKGSRC or PREFER_NATIVE.  If
a package is specified in neither or in both variables, then PREFER_PKGSRC
has precedence over PREFER_NATIVE.

Reorganize code so that any dependencies are checked as part of deciding
whether the software is built-in or not.  This facilitates implementing
the forthcoming PKGSRC_NATIVE variable.

Raise BUILDLINK_DEPENDS.freetype2 to at least 2.1.3.
Even 2.0.9 is not good enough for newer fontconfig; for example,
gtk2 won't buildlink correctly (and will use older X version of
include/freetype2/freetype/ftbdf.h) and libfontconfig needs
FT_Get_BDF_Property which is not defined.

No PKGREVISION bump is needed, because would not even build in
first place.

If we're passing through MAKEFLAGS variables whose values may contain
spaces, use the :Q modifier instead of double-quoting the value.  This
avoids breakage when executing the just-in-time su targets.

Make PREFER_PKGSRC just yes/no or a list of packages.  This makes it
simpler to understand.

Rename BUILDLINK_PREFER_PKGSRC to PREFER_PKGSRC so that we can use its
value outside of buildlink-related files.

Support a new global variable:

BUILDLINK_PREFER_PKGSRC
	This variable determines whether or not to prefer the pkgsrc
	versions of software that is also present in the base system.

	This variable is multi-state:
		defined, or "yes"	always prefer the pkgsrc versions
		not defined, or "no"	only use the pkgsrc versions if
					needed by dependency requirements

	This can also take a list of packages for which to prefer the
	pkgsrc-installed software.  The package names may be found by
	consulting the value added to BUILDLINK_PACKAGES in the
	buildlink[23].mk files for that package.

Support BUILDLINK_DEPENDS.<pkg> being a list of values.

Make sure that <freetype/freetype.h> is found.  Also if we use the
XFree86-supplied freetype2, then set USE_X11.

Use S/+$// instead of C/\+$// to save a backslash.  Very highly
recommended by seb :)

Sow BUILDLINK_USE_BUILTIN.<pkg> and reap _NEED_<PKG> variables.

Re-arrange to match example buildlink3.mk file in bsd.buildlink3.mk.

Match the buildlink3.mk guidelines set out in revision 1.22 of
bsd.buildlink3.mk.

Conform to latest buildlink3.mk guidelines using *_BUILDLINK3_MK guards
to protect more parts of buildlink3.mk files against multiple inclusion.

Provide definitions for BUILDLINK_PREFIX.<pkg> when the dependency may be
satisfied by a base system (X11R6) component.

Need to use :C instead of :S to get the "pop" action to work properly.

Move BUILDLINK_CHECK_BUILTIN.<pkg> documentation into bsd.buildlink3.mk.

Add some buildlink3.mk files needed by x11-links>=0.13.
