delete_transient action

[donncha]

Please add a "delete_transient_" action to the function delete_transient().

function delete_transient($transient) {
        global $_wp_using_ext_object_cache, $wpdb;

        do_action( 'delete_transient_' . $transient );

In WordPress MU ​it's used to override the upgrade variables for update_core, plugins and themes checking.

Oops, forgot another one. MU has the following filter in set_transient():

$value = apply_filters( 'pre_set_transient_' . $transient, $value );

Again, for the same reasoning. One of the things to sort out before merging.

If this wasn't already in, I'm pretty sure it was, then it was handled in #10788.
