[patch] Separating ZEND_METHOD and ZEND_FUNCTION

Hi, following a recent discussion on IRC I'd like to propose a little patch separating ZEND_FUNCTION and ZEND_METHOD. Currently functions declared as ZEND_FUNCTION are named zif_exported_name. Class methods are exported as zif_class_method. If you try to create a PHP function called foo_bar but already have some class foo with a method bar this leads to a "redefinition of `zif_foo_bar`". The attached patch solves this kind of issues by prefixing methods with zim_ (with m like in method) instead of zif_. Additionally it might help a bit while debugging since you can see wether you're in some class/object or a function context. As always the patch is also available at my repository on http://svn.schlueters.de/phpatches/HEAD/zend_separate_zend_method.diff johannes
