update to php-4.3.0

This needs testing; most major change is the fact that PEAR now works ... I've attached a sample PEAR port (pear-Log), and please play with the various 'pear list/show' commands and make sure all works as intended.

You need to add a file with this line into /usr/ports/infrastructure/mk/pear.port.mk

.include "${PORTSDIR}/www/php4/pear/files/pear.port.mk"

I've also got ports for various other PEAR modules, but one should be sufficient for testing.
