Subject: [PATCH] Add FILTER_VALIDATE_BOOL as alias for FILTER_VALIDATE_BOOLEAN

Both filters are equivalent, but FILTER_VALIDATE_BOOL uses our
canonical name for the type (the only one permitted in type
declarations for example), so the new name is preferred long
term.

The old name may be deprecated in the future, but no specific
timeline is planned.
