Log message:
Remove net/netbsd-tap.  NetBSD 2.0 is just too old;  later versions of
NetBSD have tap(4) in the kernel.

Log message:
Drop clauses 3 and 4 from TNF licenses

Log message:
"BUILD_ENV" was misnamed.  It's actually the environment that is passed
to all internal recursive make processes.  As such, rename it to
"PKGSRC_MAKE_ENV".

XXX Note, some of the usage of this variable in package Makefiles seems
XXX incorrect.  They probably want "MAKE_ENV", which is the environment
XXX passed to the make process when running "make" within ${WRKSRC}.

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:
Avoid extra stat() calls by not repeatedly checking whether a file
exists on the disk -- we can just check whether a variable defined by
find-files.mk is "__nonexistent__" or not.

Log message:
Fixed pkglint warnings.

Log message:
Make netbsd-tap compile on NetBSD 3.99.6+ (sysctl constification).
