Comment and term meta lazyloading for `WP_Query` loops, introduced in 4.4,
depended on filter callback methods belonging to `WP_Query` objects. This meant
storing `WP_Query` objects in the `$wp_filter` global (via `add_filter()`),
requiring that PHP retain the objects in memory, even when the local variables
would typically be expunged during normal garbage collection. In cases where a
large number of `WP_Query` objects were instantiated on a single pageload,
and/or where the contents of the `WP_Query` objects were quite large, serious
performance issues could result.
We skirt this problem by moving metadata lazyloading out of `WP_Query`. The
new `WP_Metadata_Lazyloader` class acts as a lazyload queue. Query instances
register items whose metadata should be lazyloaded - such as post terms, or
comments - and a `WP_Metadata_Lazyloader` method will intercept comment and
term meta requests to perform the cache priming. Since `WP_Metadata_Lazyloader`
instances are far smaller than `WP_Query` (containing only object IDs), and
clean up after themselves far better than the previous `WP_Query` methods (bp
only running their callbacks a single time for a given set of queued objects),
the resource use is decreased dramatically.
See [36525] for an earlier step in this direction.

`$blog_id` is used in both single and multisite configurations as a global variable, though has never been explicitly marked as such in the global scope. This can cause confusion depending on how core is loaded.

For the past 6 years, WordPress has operated as an oEmbed consumer, allowing users to easily embed content from other sites. By adding oEmbed provider support, this allows any oEmbed consumer to embed posts from WordPress sites.
In addition to creating an oEmbed provider, WordPress' oEmbed consumer code has been enhanced to work with any site that provides oEmbed data (as long as it matches some strict security rules), and provides a preview from within the post editor.
For security, embeds appear within a sandboxed iframe - the iframe content is a template that can be styled or replaced entirely by the theme on the provider site.

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.

`class-http.php` requires functions from `http.php`, so loading it by itself wouldn't have worked.
Creates:
`class-wp-http-cookie.php`
`class-wp-http-curl.php`
`class-wp-http-encoding.php`
`class-wp-http-proxy.php`
`class-wp-http-streams.php`
`http-functions.php`
`WP_Http` remains in `class-http.php`.
`http.php` contains only top-level code. Class files only contain classes. Functions file only contains functions.

Sessions are stored in usermeta via WP_User_Meta_Session_Tokens, which extends the abstract WP_Session_Tokens class. Extending WP_Session_Tokens can allow for alternative storage, such as a separate table or Redis.
Introduces some simple APIs for session listing and destruction, such as wp_get_active_sessions() and wp_destroy_all_sessions().
This invalidates all existing authentication cookies, as a new segment (the session token) has been added to them.

* All WordPress files move to a src/ directory.
* New task runner (Grunt), configured to copy a built WordPress to build/.
* svn:ignore and .gitignore for Gruntfile.js, wp-config.php, and node.js.
* Remove Akismet external from develop.svn. Still exists in core.svn.
* Drop minified files from src/. The build process will now generate these.
