Convert Before{Selection|Value}Change to return a boolchromium/3366
Both of these IPDF_FormNotify methods return {-1, 0, 1} but all callsites only care about < 0 and >= 0. Convert to return a bool that treats the 0 and 1 case as the same. This also makse sense in terms of the API because false means validation failure. The case where 0 was used was a place holder for we didn't try for this field type, which also implicitly means validation passed.
