Sergey Biryukov 897f004a9c General: Replace older-style PHP type conversion functions with type casts.
This improves performance, readability, and consistency throughout core.

* `intval()` → `(int)`
* `strval()` → `(string)`
* `floatval()` → `(float)`

Sergey Biryukov 47ed56f38f Code Modernization: Replace `dirname( __FILE__ )` calls with `__DIR__` magic constant.
This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.

This commit also includes:

* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
 * `wp-admin/admin-header.php`
 * `wp-admin/admin-footer.php`
 * `wp-includes/version.php`

Gary Pendergast 56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
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.

Dion Hulse 3517dc0b8b Updates: Partially revert [42584], as this branch of code should always be run after a core update check.
This code branch is responsible for running all autoupdates, including plugins and themes - which should run regardless of if there's a core autoupdate available.

This revert does not revert the `$timeout` changes, as these should still use cached data if it's available.
Ideally this should be decoupled from the core update check to allow background updates to operate even when the core update check is disabled or running more often than twice daily.

Dion Hulse 14068105f7 Updates: Only trigger Background Update processes from within the core update check when a core autoupdate is on offer.
This change reduces the number of API calls which WordPress makes to api.wordpress.org during release windows.

Previously the background updates would run upon every core update transient refresh, however now they'll only run if there's an update available.
The change also increases the cache period for plugin & theme checks when running via the cron, from never-cache to 2 hours, which should hopefully reduce the number of needless API calls.

John Blackbourn 807bc5a6c9 Users: Introduce the concept of a large site in order to speed up the Users screen when there are many users.
Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.

This introduces some new functions:

* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`

A corresponding `wp_is_large_user_count` filter is also introduced.

Scott Taylor 6a529648cf Bootstrap: Autoload classes using a Composer-generated PHP 5.2-compatible Autoloader.
* `wp-admin` and `wp-includes` are scanned for classes to autoload
* Several 3rd-party and Ryan McCue-shaped libraries are excluded when the classmap is generated, see `composer.json`: `autoload.exclude-from-classmap`
* `wp-vendor/autoload_52.php` is included at the top of `wp-settings.php` - no changes need to be made to unit tests to include the autoloader
* An avalanche of `require()` and `require_once()` calls that loaded class files have been removed from the codebase.

The following files have been added to `svn:ignore` - they are not 5.2-compatible and fail during pre-commit:
* src/wp-vendor/autoload.php
* src/wp-vendor/composer/autoload_real.php
* src/wp-vendor/composer/autoload_static.php
* src/wp-vendor/composer/ClassLoader.php

We favor these files instead:
* src/wp-vendor/autoload_52.php
* src/wp-vendor/composer/autoload_real_52.php
* src/wp-vendor/composer/ClassLoader52.php

When new PHP classes are added to the codebase, simply run `composer install` or `composer update` from the project root to update the autoloader.

The future is now.

Dion Hulse 06a3f799e7 Background Updates: Remove the 7am/7pm background update check. This check was made redundant by [28129] as background updates are now run after a version check takes place.

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.

Scott Taylor 66a9c83284 Add missing doc blocks to `update.php`:
* `wp_version_check()`, `wp_update_plugins()`, and `wp_update_themes()` do not return meaningful responses, and their responses are never handled by core. As such, they shouldn't alternately return `void` or `false`. "Returning" in those functions is just "bailing"
* In the same functions, `version.php` doesn't need to load if `WP_INSTALLING` is defined - the function will immediately bail, the values will never be read, and the globals won't be reset. I have unified the approach in all 3 functions.
* When returning filtered `$locale`, there is no need to set the variable twice.
* In `_maybe_update_core()`, `isset()` can take multiple values to bail before the call to `time()`, if necessary. This is a micro-optimization to prevent PHP from hitting the OS unnecessarily.
