Deprecations

- helper methods for various errors were deprecated, and their roles are now performed by the corresponding exception classes. For example, the call to the `request_validation_error("error message")` function can be replaced with the `raise RequestValidationError("error message")` exception class. The methods will be available until the next major release (160).
