This method provides generalized, consistent type casting more versatile than PHP's basic type juggling while hiding the significant complexity in achieving this.
While this commit does not change any existing code to use the new method, the intent is for both API handlers and database drivers to use the same basic rules for type conversion while still allowing for differing failure modes.
- Database functions now accept any input, but throw typeViolation exceptions where appropriate instead of idMissing or subjectMissing
- Added unit tests for the new Misc\ValueInfo static class
- Added ValueInfo::id() method to centrally validate database IDs, and made use of it consistently
- Made use of PHP's filter_var() function where appropriate when validating or sanitizing input
- Made the NCN protocol handler reject most invalid IDs before handing off to method handlers
- Made NCN's feedUpdate and subscriptionMove methods return 422 on invalid input
- Adjusted several tests to handler type violations
