This is the first big step to supporting arbitrary domains and paths. In this new approach, sites are detected first where possible, then the network is inferred. Allows filtering for arbitrary path segments, smooths out some weirdness, and removes various restrictions. A sunrise plugin could do much of its work by adding filters, if those are even needed.

Tries to get network detection under control by simplifying wpmu_current_site(). It now also pops off each subdomain to find a more general match. Adds unit tests for get_network_by_path() and a new network factory for unit tests.
Much of this is likely to change in 3.9 as more of ms-load.php and ms-settings.php gets hacked to bits.

wp-includes/admin-bar.php:
* Replace get_admin_url() and get_home_url() with admin_url() and home_url() and place them inside a switch/restore. Likewise replace current_user_can_for_blog() with current_user_can(). This avoids doing multiple switch restores.
wp-includes/ms-blogs.php:
* Deprecate the $validate argument to switch_to_blog(). This avoids a not very necessary call to get_blog_details(), possibly saving a few queries.
* Use $_wp_switched and $_wp_switched_stack instead of $switched and $switched_stack to make it less likely these globals will be stomped.
* Use GLOBALS to access blog_id and other globals. I've preferred this style lately since it makes it obvious a global is being used and avoids global blog_id being stomped by a local variable.
* Lose some is_object() checks. wp_get_current_user() always returns an object, for example.
* Call the new WP_Roles::reinit() method.
wp-includes/class-wp-xmlrpc-server.php:
* Replace current_user_can_for_blog() with current_user_can() and move it inside the switch/restore pair. This eliminates a switch/restore.
wp-includes/capabilities.php:
* Use array_keys() instead of $role => $data since $data is unused. I *think* this is a bit faster.
* Introduce WP_Roles::reinit(). This reinitializes WP_Roles and is used after switch_to_blog() has already update the blog ID in the wpdb object. If a global roles array is being used instead of the db, reinit is skipped.
* current_user_can_for_blog() now does a switch/restore. It didn't before meaning it could be reinitializing the user with the wrong role information for the current blog.
wp-includes/ms-settings.php:
* Define $_wp_switched_stack and $_wp_switched. This way switch_to_blog() and restore_current_blog() can rely on it being set.
wp-settings.php:
* Instantiate the WP_Roles global. This was it is always defined during init. To remove the WP_Roles checks from WP_Role and WP_User this would probably have to move before plugins are loaded, which might not be a good thing.
wp-includes/functions.php:
* Update wp_upload_dir() to reference _wp_switched.
