[spine-c] Fix crashes in skins or animations error handling (#2491)

Browse Source 
* Fix android-specific rotation issue. bone->arotation == NaN, in some specific cases during update bones, cause squared value can been very smoll but still negative anyway and create NaN value

* Fix crash at spSkeletonData_dispose() while handling problems in skeleton in SkeletonBinary/SkeletonJson.
Use increase counts instead directly put counts value for avoid problems at early dispose vectors

* additional commit for prev revision
