This v1 marries Jetpack's Site Icon module with the Media Modal, reusing code
from the Custom Header admin. For now, the core-provided icons will be limited
to a favicon, an iOS app icon, and a Windows tile icon, leaving `.ico` support
and additional icons to plugins to add.

Feeds: ensure build/update date matches current query.
Displaying the correct build date in feeds is as important today as it was twelve years ago when this ticket was opened.
Fix an issue where all feeds in WordPress showed the same date for their last build date (the datapoint is `lastBuildDate`, `updated` or `dc:date` depending on the feed type).
Introduce a new `get_last_build_date` filter to adjust the date used for `lastBuildDate`. Developers who previously filtered `get_lastcommentmodified` to alter feed dates should use this filter instead.
* `get_last_build_date` extracts the latest post (or comment) in the current WP_Query object.
* In all feed templates, use `get_last_build_date` vs `get_lastpostmodified( 'GMT' );`.

Feeds: ensure build/update date matches current query.
Displaying the correct build date in feeds is as important today as it was twelve years ago when this ticket was opened.
Fix an issue where all feeds in WordPress showed the same date for their last build date (the datapoint is `lastBuildDate`, `updated` or `dc:date` depending on the feed type).
Introduce a new `get_last_build_date` filter to adjust the date used for `lastBuildDate`. Developers who previously filtered `get_lastcommentmodified` to alter feed dates should use this filter instead.
* `get_last_build_date` extracts the latest post (or comment) in the current WP_Query object.
* In all feed templates, use `get_last_build_date` vs `get_lastpostmodified( 'GMT' );`.
