Several Importers call create_function() multiple times per imported post

[mdawaffe]

The WordPress, Blogger, Blogware, LiveJournal, and RSS importers all call create_function() one or more times per post.

Importing a lot of posts means creating a lot of functions, all of which do the same thing. This can lead to fatal memory allocation errors.

Attached replaces each create_function() call with a hardcoded function.

Patch in UNTESTED.

(In [11964]) Use hard-coded functions instead of create_function() in importers. Props mdawaffe. fixes #10836

ryan, please see the parameter is called $matches but you use $match later on. this is a minor bug I assume by copy/paste. please fix it.

 	532	    function _normalize_tag( $matches ) { 
 	533	        return '<' . strtolower( $match[1] ); 
 	534	    }

okay it's mdawaffe code, don't want to give false credits here.

[hakre]

the problem is in the patch mulitple times. just change the _normalize_tag() function.

idea: what about having one parent import class that provides functions for all the importers which do only extend from that class.
