* Don't lower memory limit if the current limit is greater than `WP_MAX_MEMORY_LIMIT`. * Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime. * Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value. * Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit. * Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime. * Remove a `function_exists( 'memory_get_usage' )` check. Since PHP 5.2.1 support for memory limit is always enabled. Related commits: [38011-38013] Props jrf, A5hleyRich, swissspidy, ocean90. Fixes #32075.
