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.

Replaces all uses of `*_site_option()` with the corresponding "network" function.
This excludes one usage in `wp-admin/admin-footer.php` that needs more investigation.
Props spacedmonkey.

Also adds a couple of in-DocBlock examples illustrating single key and value, and associative array usage. Retains the note about the unescaped return value.

The good news is, the point of `wp_json_encode()` is to handle those non-UTF-8 characters. It'll totally just fix them up, no problem.
Anyway, we can just ignore those warnings.

This function is one that can be called in core to indicate that a PHP4 style constructor is used. PHP4 style constructors are deprecated in PHP7.

Expand on the logic previously available as part of `is_main_network()` and provide a way to obtain the ID of the main network. Most useful in multi-network configurations.

Up to this point, various core elements' DocBlocks incorrectly included an `@internal` tag as a means for skipping the parsing process. When paired with a description (inline or otherwise), `@internal` is a valid tag meant to provide internal-only context, but not necessarily to skip parsing the entire element.
