Sergey Biryukov 532bd808c9 Code Modernization: Check the input type in validate_file().
This fixes a `preg_match_all(): Passing null to parameter #2 ($subject) of type string is deprecated` notice on PHP 8.1.

The behavior for `null` and `string` input is covered by the existing `Tests_Functions::test_validate_file()` test.

Effect: Errors down by 238, assertions up by 1920, failures down by 1.
