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.

Changes 2.8.8:

* Fixed regressions from 2.9.1 and 2.8.6:
  - Regenerated with latest glibmm to fix several empty methods.
  - ActionGroup:add(): Fix crash in alternate property get.
  - Gdk::PixbufLoader: Correct the vfunc sequence to avoid the ABI break.
* Table: Fix crash in Table_Helpers::TableList.erase().

Log message:
Fix buildlink3.mk

Log message:
Changes 2.8.7:
* Fixed a typo to fix the build when not disabling exceptions.

Changes 2.8.6:
* Fix the build when using --enable-api-properties, --enable-api-vfuncs, or
  --enable-api-exceptions when configuring glibmm.
  When using these, the API, and any API generated by gmmproc, will be
  changed. This allows users of embedded platforms to reduce the code size of *mm
  libraries and *mm-using applications, at the small cost of losing some rarely-used
  API. Alternatives exist for that API, as show in the examples.

Log message:
Changes 2.8.5:
* Removed an unnecessary file from gmmproc.

Log message:
Bump BUILDLINK_ABI_DEPENDS.png and PKGREVISION for png-1.2.9nb2 update.

Log message:
Changes 2.8.4:
* IconTheme: Avoid crash in get_search_path().
* Some code size reduction by using more static functions instead of
  anonymous namespaces, and by avoiding some code duplication.
* Windows Build:
  - MSVC++ build: Use the new /vd2 compiler option to get the new unbroken
  dynamic_cast<> with MSVC++. There are now no known problems with
  the MSVC++ build.
  - mingw32 and cygwin builds: Correct some API export/import problems.

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:
Changes 2.8.3:
* gtkmm.h: Include menutoolbutton.h and tearoffmenuitem.h.
* Container: Avoid crash when connecting to the remove signal.
* TreeView: Commented-out uses of g_assert() in header to avoid
  warning that the statement has no effect
* Win32: Enable Plug and Socket classes
