Toward importing of PHP 5.4.x

[Takahiro Kambe <taca%NetBSD.org@localhost>]

Hi,

I'm working on importing of PHP 5.4.x and slightly changes.

1. Stop special meaning of '5' with PHP_VERSION_DEFAULT or
   PHP_VERSIONS_ACCEPTED except backward compatibility (as 52).

2. Make meta-packages/php*-extensions simply collection of PHP
   extensions bundled with the PHP original distribution file.

My work isn't completed yet, but hopefuly in one or two weeks.

Best regards.
