Log message:
Do not define a symbol in a header file.  This fixes "multiple definitions"
errors on Darwin.

Log message:
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

Log message:
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.

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

Log message:
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).

Log message:
Include sys/time.h before sys/resource.h.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 digests to the SHA1 ones.

Log message:
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.

Log message:
Mechanical changes to package PLISTs to make use of LIBTOOLIZE_PLIST.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:

	lib/libfoo.a
	lib/libfoo.la
	lib/libfoo.so
	lib/libfoo.so.0
	lib/libfoo.so.0.1

one simply needs:

	lib/libfoo.la

and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.

Also make LIBTOOLIZE_PLIST default to "yes".
