Konstantin Obenland c69e96422b Themes: Improve document title output.
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.
Deprecates `wp_title()`.

Fixes #31078.

Boone Gorges 0e7c1d3b14 Use `wp_installing()` instead of `WP_INSTALLING` constant.
The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.

A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available.  However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.

The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.

Aaron Jorbin c09b0477b2 Flush rewrite rules upon theme switch
Themes can ( and do ) but shouldn't include custom rewrite rules.This can lead to hard to debug issues for theme authors. Theme changes are not a ultra common conclusion. Flushing the rewrite rules on theme switch will lead to a clean slate for each theme which helps make debugging easier.

And @nacin said we should do this 5 years ago at WordCamp Mid Atlantic.

Scott Taylor fe6b5983df In PHP 5.0.0, `is_a()` became deprecated in favour of the `instanceof` operator. Calling `is_a()` would result in an `E_STRICT` warning.
In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.

To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.

`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.

Scott Taylor fc843ce4d0 There are some random `add_action()` and `add_filter()` calls littered around some files in `wp-includes/`. These should be moved to `wp-includes/default-filters.php` with the rest of the registered hooks. It seems like this was the best practice for awhile and then we randomly stopped. This file loads way before any of the includes, so the hooks will be registered for any request that loads WordPress, even `SHORTINIT` - a lot of the hooks registered won't run anyways (that's already the case).
