Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
The php_pdo* packages have not kept step with PHP changes. The PDO
components are now built into PHP rather than maintained separately in
PECL. The old PECL versions are unmaintained and haven't been altered
for 3 years. This is confusing as the package versions report themselves
to be 5.2.9.1.0.2, etc. but they are in fact based on the 5.1.x code-base.

Therefore, we need to switch to building the PDO modules like any other
PHP module.

A side-effect of this is that the PECL version number will get stripped
off the end meaning that the new version numbers are just 5.2.9 instead
of 5.2.9.1.0.2 (for example). Unfortunately, 5.2.9 is considered to be
older than 5.2.9.1.0.2 meaning that it will appear as though a downgrade
has taken place. Therefore, while we are still using PHP 5.2.9, add .99 on
the end (i.e. 5.2.9.99) so that the package appears newer. When PHP 5.2.10
is released this can be removed (the module.mk file explicitly cgecks for
5.2.9 before adding the .99 suffix so that it will not alter 5.2.10 if the
hack is forgotten. However, for the record, when 5.2.10 is released,
php-pdo/module.mk can be removed along with the references to it in each
php-pdo*/Makefile

Log message:
Don't abuse b3. It should not do things like include bsd.pkg.mk, so fix
up the packages that use it instead.

Log message:
Add DESTDIR support.

allow this package to build properly on Mac OS X as shared extension

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:
Rename all PHP 4 packages to php4-*, all PHP 5 packages to php5-*,
all PEAR packages to php?-pear-* and all Apache packages to ap13-* or
ap2-* respectively. Add new variables to simplify the Makefile
handling. Add CONFLICTS on the old names. Reset revisions of bumped
packages. ap-php will now depend on the default Apache and PHP version.
All programs using it have an implicit option of the Apache version
as well.

OK from jlam@ and adrianp@.
