WP_Query::get_posts needs a filter on the query_vars

[AaronCampbell]

You can filter the WHERE string after it's been assembled by WP_Query::get_posts but you can't filter the query vars that are used to build that string BEFORE it's built. It would be REALLY nice to have that ability, so that a plugin could simply adjust the query vars and still let WP_Query::get_posts build the WHERE (JOIN, etc).

Adds 'query_vars' filter

making it viewable

What about 'parse_query'?

And 'query_string' for the main query.

[ryan]

There's already a query_vars filter in WP::parse_request(). That filters the vars for the main query. If you really need a filter within WP_query(), it needs to have a different name.

If the existing query_vars filter does not suffice, re-open with a patch that avoids name collision.
