/**
 * WordPress Filesystem Class for implementing SSH2
 *
 * To use this class you must follow these steps for PHP 5.2.6+
 *
 * {@link http://kevin.vanzonneveld.net/techblog/article/make_ssh_connections_with_php/ - Installation Notes}
 *
 * Compile libssh2 (Note: Only 0.14 is officially working with PHP 5.2.6+ right now, But many users have found the latest versions work)
 *
 * cd /usr/src
 * wget https://www.libssh2.org/download/libssh2-0.14.tar.gz
 * tar -zxvf libssh2-0.14.tar.gz
 * cd libssh2-0.14/
 * ./configure
 * make all install
 *
 * Note: Do not leave the directory yet!
 *
 * Enter: pecl install -f ssh2
 *
 * Copy the ssh.so file it creates to your PHP Module Directory.
 * Open up your PHP.INI file and look for where extensions are placed.
 * Add in your PHP.ini file: extension=ssh2.so
 *
 * Restart Apache!
 * Check phpinfo() streams to confirm that: ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2.sftp  exist.
 *
 * Note: As of WordPress 2.8, this utilizes the PHP5+ function `stream_get_contents()`.
 *
 * @since 2.7.0

/**
 * Retrieves theme installer pages from the WordPress.org Themes API.
 *
 * It is possible for a theme to override the Themes API result with three
 * filters. Assume this is for themes, which can extend on the Theme Info to
 * offer more choices. This is very powerful and must be used with care, when
 * overriding the filters.
 *
 * The first filter, {@see 'themes_api_args'}, is for the args and gives the action
 * as the second parameter. The hook for {@see 'themes_api_args'} must ensure that
 * an object is returned.
 *
 * The second filter, {@see 'themes_api'}, allows a plugin to override the WordPress.org
 * Theme API entirely. If `$action` is 'query_themes', 'theme_information', or 'feature_list',
 * an object MUST be passed. If `$action` is 'hot_tags', an array should be passed.
 *
 * Finally, the third filter, {@see 'themes_api_result'}, makes it possible to filter the
 * response object or array, depending on the `$action` type.
 *
 * Supported arguments per action:
 *
 * | Argument Name      | 'query_themes' | 'theme_information' | 'hot_tags' | 'feature_list'   |
