 {{{
 #!CommitTicketReference repository="" revision="21790"
 * Introduce wp_kses_allowed_html() which accepts a context string and
 returns an array of allowed tags.
  * Remove explicit declarations of class, id, style, and title from
 $allowedposttags
  * Dynamicallly add global attributes to every tag for the 'post' context
  * No longer calls wp_kses_array_lc() every time wp_kses() runs. Instead
 it runs once if CUSTOM_TAGS is true. Plugins directly passing a custom
 allowed_html array will no longer get the lc treatment. Keep an eye out
 for problems with this.
  * wp_kses_data() and wp_filter_kses() pass current_filter() for the
 $allowed_html argument to wp_kses().
  * wp_kses_allowed_html() handles being passed a filter name for a
 context. If the filter is not a recognized one it defaults to using
 $allowedtags as was done before for wp_kses_data() and wp_filter_kses().
  * wp_kses_allowed_html() recognizes user_description and
 pre_user_description out of the box. For these it takes $allowedtags and
 inserts rel attribute support.
  * wp_kses_allowed_html() allows plugins to override the return values for
 the default contexts and support arbitrary contexts via a
 wp_kses_allowed_html filter.
  * wp_kses_hook() can now pass a string context for $allowed_html to the
 pre_kses filter. We might have to pass the result of
 wp_kses_allowed_html() instead if it turns out that plugins are digging in
 $allowed_html.
