Don't rely on differences in the value of DISTNAME that rely on
"immediate" versus "lazy" evaluation of the value.  Just explicitly
define a variable (COMPAT_PKG) that holds the value that's needed in
each of the compat* packages, and use it within Makefile.common.

This was an attempt to solve PR pkg/36863, but it doesn't look like
pkglint or lintpkgsrc understand this more straightforward variable
construction either.

* Support netbsd-* as a valid platform in EMUL_PLATFORMS.  Use the
  pkgsrc/emulator/compat* and pkgsrc/emulator/netbsd32_compat* packages
  to provide the necessary shared libraries to run dynamically linked
  NetBSD binaries from the days of yore.

* Add some additional compat* packages for completeness:

	compat15, compat20, compat30

* Modify the compat* packages so that "compatNM" only provides files
  that aren't in "NetBSD-N.(M+1)".  For example, compat12 only provides
  files that don't exist in NetBSD-1.3.x, compat13 only provides files
  that don't exist in NetBSD-1.4.x, etc.

  As a result, if you are running NetBSD-3.0/alpha and want to run a
  1.3 dynamically linked binary, there is an automatic dependency
  chain that causes the following packages to be installed:

	compat13, compat14, compat15, compat16, compat20

  There are some deviations from this dependency chain on platforms
  that have changed executable formats, e.g. i386, m68, sparc, etc.
  However, in general pkgsrc will require that you have the necessary
  COMPAT_* options in your kernel to match the installed compat*
  packages.  This restriction is an artificial one imposed by pkgsrc,
  but allows for a single set of distfiles to be used on all versions
  of NetBSD.

* Provide compat* package support for every supported architecture
  of NetBSD.  Verily, it is now possible to run 1.2 binaries on
  NetBSD-1.5.3/pc532 by installing the compat12 package from pkgsrc.
  Rejoice, one and all!

* The netbsd32_compat* packages mirror the corresponding compat*
  packages for use by sparc64 and x86_64 to allow running 32-bit
  binaries with COMPAT_NETBSD32 kernel support.  The "extras" packages
  supply the additional shared libraries from the corresponding release
  of NetBSD so that the set of files in /emul/netbsd32 will be complete.

* pkgsrc/emulators/compat_netbsd contains infrastructure files shared
  by all of the compat* packages.

Mark as NO_SRC_ON_FTP -- files are already in MASTER_SITE_LOCAL.

Move the check-shlibs target from bsd.pkg.mk to bsd.pkg.check.mk where
it will live with other "check" targets run after package installation.

Get rid of SHLIB_HANDLING, whose meaning had mutated over the years
from one thing to another.  Currently, it is used to basically note
whether the system's "ldd" command can be usefully run on the package's
binaries and libraries.  Rename this variable to CHECK_SHLIBS_SUPPORTED
for more clarity.

CHECK_SHLIBS is now a variable set exclusively by the user in /etc/mk.conf
to note whether the check for missing run-time search paths is performed
after a package is installed.  It defaults to "no" unless PKG_DEVELOPER
is set.

Modify the pkginstall framework so that it manages all aspects of
INSTALL/DEINSTALL script creation within pkgsrc.

If an INSTALL or DEINSTALL script is found in the package directory,
it is automatically used as a template for the pkginstall-generated
scripts.  If instead, they should be used simply as the full scripts,
then the package Makefile should set INSTALL_SRC or DEINSTALL_SRC
explicitly, e.g.:

	INSTALL_SRC=	${PKGDIR}/INSTALL
	DEINSTALL_SRC=	# emtpy

As part of the restructuring of the pkginstall framework internals,
we now *always* generate temporary INSTALL or DEINSTALL scripts.  By
comparing these temporary scripts with minimal INSTALL/DEINSTALL
scripts formed from only the base templates, we determine whether or
not the INSTALL/DEINSTALL scripts are actually needed by the package
(see the generate-install-scripts target in bsd.pkginstall.mk).

In addition, more variables in the framework have been made private.
The *_EXTRA_TMPL variables have been renamed to *_TEMPLATE, which are
more sensible names given the very few exported variables in this
framework.  The only public variables relating to the templates are:

	INSTALL_SRC		INSTALL_TEMPLATE
	DEINSTALL_SRC		DEINSTALL_TEMPLATE
				HEADER_TEMPLATE

The packages in pkgsrc have been modified to reflect the changes in
the pkginstall framework.

Point MAINTAINER to pkgsrc-users@NetBSD.org in the case where no
developer is officially maintaining the package.

The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list).  Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

Remove USE_PKGINSTALL from pkgsrc now that mk/install/pkginstall.mk
automatically detects whether we want the pkginstall machinery to be
used by the package Makefile.

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

Set NO_BUILD and NO_MTREE to yes instead of #defined.

Prevent warnings during bulk dependency tree creation for ports that
cannot use these packages.

Add definitions for DEINSTALL_EXTRA_TMPL and INSTALL_EXTRA_TMPL if
USE_PKGINSTALL is "YES".  bsd.pkg.install.mk will no longer automatically
pick up a INSTALL/DEINSTALL script in the package directory and assume that
you want it for the corresponding *_EXTRA_TMPL variable.

Convert to use bsd.pkg.install.mk.

s/netbsd.org/NetBSD.org/

Use tech-pkg@ in favor of packages@ as MAINTAINER for orphaned packages.
Should anybody feel like they could be the maintainer for any of thewe packages,
please adjust.

Update to new COMMENT style: COMMENT var in Makefile instead of pkg/COMMENT.

Set MAINTAINER to packages@netbsd.org.

Group logical expressions correctly.

Run ldconfig after installing/deinstalling shared libraries.  We need to
do this manually since it's not automatically handled by bsd.pkg.mk.

Make these install into /usr on most platforms, and into /emul/aout/usr
on platforms transitioning to ELF (currently only i386).  The /emul/aout
installation occurs much like the suse_linux and freebsd_lib packages.

Also add SHLIB_HANDLING=NO to ensure library links aren't clobbered.

This should fix PR#9011.

remove unnecessary whitespace

Don't use "{}" or "[]" in "ONLY_FOR_PLATFORM" or "NOT_FOR_PLATFORM"
because "bsd.pkg.mk" can't handle those patterns. Fixes PR pkg/7808
by Chris Demetriou.

Change {ONLY,NOT}_FOR_{ARCH,OPSYS} format to {ONLY,NOT}_FOR_PLATFORM
pattern match format.  Minor pkglint along the way.

Explicitly install these into /usr in order to avoid messing with
ld.so.conf on a.out and LD_LIBRARY_PATH on ELF.

ONLY_FOR_OPSYS=NetBSD.

The Grand Homepagification:
	- New, optional Makefile variable HOMEPAGE, specifies a URL for
	  the home page of the software if it has one.
	- The value of HOMEPAGE is used to add a link from the
	  README.html files.
	- pkglint updated to know about it.  The "correct" location for
	  HOMEPAGE in the Makefile is after MAINTAINER, in that same
	  section.

Fix DISTNAME/PKGNAME differences.

Consolidate and clean up compat11/compat12.  Now there is only one pkg
(compat12), which uses MACHINE_ARCH and does not supply libkvm.

Use automatic shared object handling

Don't mirror distribution files which are kept locally anyway.

Use "ONLY_FOR_ARCHS" instead of "pre-fetch" hack and fix broken package
list creation.

Use the bsd.pkg.mk and bsd.pkg.subdir.mk files in the pkgsrc tree.
Remove redundant (and sometimes erroneous) comments.

ONLY_FOR_ARCHS doesn't check ARCH; it checks MACHINE_ARCH.  Change this to
a shell check as changing <bsd.port.mk> is more than it should be.

portlint: remove double "post-install:"; reorder EXTRACT_SUFX.

Import of NetBSD 1.2[.1] shared library compat package
