Comment:

 attachment:21663.10.diff​

 * Updates attachment:21663.7.diff to apply cleanly against trunk
 * Remove the temporary `E_DEPRECATED` check added in 3.8
 * Fix a bug where `set_charset()` wouldn’t work for MySQL 5.0.0 -> 5.0.5

 I’m a big fan of eventually moving to a driver-style WPDB, like
 markoheijnen’s plugin, but I don’t think we’re ready for that, yet.
 Changes to WPDB can have far reaching effects, so we need to move in baby
 steps, and I like aaroncampbell’s approach as a first step.

 This patch will need to be updated for #26847 and (hopefully) #5932, but
 I’d like to see it get into 3.9 early, so we can give it as much soaking
 time as possible. Changing over to mysqli will probably break any plugins
 that call the `mysql_*()` functions directly, so we’ll need to give the
 plugin authors as much time as possible to update their plugins.
