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' );`.

WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.
This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.
Fixes#44600.

Fixes bug where an invalid Last-Modified value would be returned in feed requests for sites that had 0 items to return. Comment or post feeds will now return the current timestamp as the Last-Modified header value. Example: a request for the comments feed for a site without any comments.
Replaced use of the local static variable `$cache_lastcommentmodified` to store the modified date in `get_lastcommentmodified()` with the Object Cache API. The `get_lastcommentmodified()` function returns early if there is a cached value and returns `false` if there where no comments found. Introduced `_clear_modified_cache_on_transition_comment_status()` to flush the `lastcommentmodified` cache key when a comment enters or leaves approval status. In `get_lastpostmodified()` return early if there is a cached value and return `false` if there are no posts found.

Introduces more flexibility in filtering all parts of the document title,the
separator, and a way to short-circuit title generation. Plugins can now also
check for theme support and reliably filter the entire output. See #18548.
