 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.

 See #36335.
