4.5.0:

  * Adds supports for compiling and linking with BerkeleyDB 4.5
  * Python Bug #1599782: Fix segfault on bsddb.db.DB().type() due to
    releasing the GIL when it shouldn't.  (nnorowitz)
  * Fixes a bug with bsddb.DB.stat where the flags and txn keyword
    arguments are transposed.
  * change test cases to use tempfile.gettempdir()

  * pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
    methods now allow their database parameter to be None as the

PKGREVISION bump for db4 shlib name change.

Log message:
we can't have PYTHON_VERSIONS_ACCEPTED in buildlink3 files because
this might conflict with definitions in Makefiles
noticed by Jeremy C. Reed

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:
Fixed pkglint warnings.

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