Use int instead of integer in type errors

PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".

add missing SKIPIF sections

- MFH: invalid filter id should not return unsafe values

fix test

Unify handling of return values on validation failure and var not found

- MFH: Change validating filters to return "null" on failure so that they can be
distinguised from the value "false" which might be valid as well.

Refactor the filter extension
- Cleanup API
- Added handling for circular references
- Renamed functions.

# Original patch by Pierre

- MFH: pecl bug #8316,
empty strings are not int or float, return false (due to popular demand)
