This sets a referrer policy of `same-origin` which adds hardening by preventing a referrer being sent from the admin area or login screens to other origins. This helps prevent unwanted exposure of potentially sensitive information that may be contained within URLs.
This change introduces a new filter, `admin_referrer_policy`, for filtering the referrer policy header value. The header can be disabled if necessary by removing the `wp_admin_headers` action from the `admin_init` and `login_init` hooks.

This adds this previously Multisite-only functionality to single site installations too. This change prevents accidental or erroneous email address changes from potentially locking users out of their site.

Having a view mode switcher nestled within table navigation makes no sense, especially now that it's a sticky user option. While less convenient for frequent switching, there is no evidence as of yet that there is a large userbase of frequent view mode switchers.
Introduces a filter for `view_mode_post_types`, which by default is all hierarchical post types with edit UI on.

This change also makes it bail early (without writing) if the markers content is the same as the existing, and uses `ftell()` rather than `$bytes` for the location to truncate the file to - based on the file pointer being at the end of the written stream.

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.

The call to `flock()` is an exclusive advisory lock, which in my testing only PHP respects (apache continues to read it).
Not all filesystems support locking (remote NFS mounts for example) so this offers minimal benefit to those platforms, but offers much better protection against file corruption on systems which do support it.
The call is blocking, so a second process will wait for the first to complete before writing if supported.

`admin-filters.php`
`ms-admin-filters.php`
There are random actions and filters littered among files like `misc.php`. These files contain functions that won't work outside of admin context and are typically only loaded in files that have already loaded the admin bootstrap.

These no longer return upon refreshing the page when JS is on and working, so users should be able to dismiss them. This is particularly important on the post edit screen when DFW is triggered, but pretty much all notices can be dismissed if needed. A post on Make/Core will follow with information on how this can be leveraged in plugins.
