Sergey Biryukov fbebb744b0 Bootstrap/Load: Remove the `wp_environment_type` and `wp_get_environment_type` filters.
Since `wp_get_environment_type()` runs too early for plugins to hook these filters, and the result is then cached in a static variable and cannot be changed later, the filters are not that useful.

The `WP_ENVIRONMENT_TYPES` and `WP_ENVIRONMENT_TYPE` constants and environment variables should be enough for now.

whyisjake 53c909a825 Mail: PHPMailer swap to use is_email for the default validator.
Prior to the PHPMailer update in 5.5, old version of the PHPMailer was setting the validator to 'auto' resulting in a sophisticated logic for determining what email address validation should be used. But the new version defaults to 'php', possibly leading to rejection of email addresses which were fine prior to the upgrade. Let's use the WordPress core function `is_email()` so that it can be fully pluggable.

TimothyBlynJacobs 86ea4f0838 REST API: Fix warning when using `set_param()` on a JSON request with no body.
In [47559] the `WP_REST_Request::set_param()` method was adjusted to try and overwrite an existing parameter definition before forcing the value in the first parameter slot. If `set_param()` was called on a request with an `application/json` content type and an empty body, a PHP warning would be issued. This was due to the JSON parameter type not being set to an array when the body is empty.

This commit avoids the warning by adding an `is_array()` check before calling `array_key_exists`. Ideally, `WP_REST_Reuest::parse_json_params()` would set the JSON parameter type to an empty array in this case, but that is too large of a change at this point in the cycle.

Sergey Biryukov df74d8f10d Revisions: Ensure the global `$post` remains the same after revision is restored.
Because `wp_insert_post()` and `wp_transition_post_status()` are called during the process, plugins can unexpectedly modify `$post`.

Sergey Biryukov d8c62b5647 Posts, Post Types: Move `get_post_states()` back to the admin for now, require the file in `WP_Customize_Nav_Menus::customize_register()` instead.
This provides a minor performance improvement by only running the function in contexts where it's needed.
