 {{{
 #!CommitTicketReference repository="" revision="62099"
 Real-time collaboration: Use prepared queries instead of *_post_meta
 functions.

 Replaces add_post_meta/update_post_meta with wpdb->insert/wpdb->update.

 This prevents a real-time editing session from invalidating WP_Query and
 various other post caches every few seconds. RTC stores awareness and sync
 information in post meta with high frequency. However, every call the
 *_post_meta functions invalidated post caches.

 This commit avoids this frequent invalidation by removing the direct
 *_post_meta calls in favor of $wpdb calls.

 Props czarate, mukesh27, paulkevan.
