Allow get_post*() and get_page*() functions to query by more than ID or using an post object.

This is similar to ticket #12726 which I just submitted but is broader. There are many functions in post.php (and probably elsewhere) that accept a $post as a lookup parameter where $post is either an ID or an object with an attribute of "ID" containing a post ID, i.e. $post->ID. It would be nice if they could optionally accept other lookup criteria such as 'path' and 'title.'

It could be something like this:

$post = get_post(new WP_PostBy('path','mypath'));
class WP_PostBy {
	var $field;
	var $value;
	function __construct($field,$value) {
		$this->field = $field;
		$this->value = $value;
	}
}

Or it could be just as simple as a two element array, i.e.

$post = get_post(array('path','mypath'));

I'll be happy to do the coding if the task is 'blessed' and any special cases that I need to handle are identified.

We have a get_user_by() function. Emulating that for pages/posts/post_types I think is what you're trying to get at with this ticket and #12726. Sounds like a good idea in theory, though strong doubts on 3.0 for it.

Cool. Wasn't really expecting it for 3.0, just wanted to get it into the queue... :-)

Fixed in #12743. Nice job sneaking that one in :-)

I'm confused. What did I sneak in? (wasn't intentional...)
