Title: update the default value for bPrefixNalAddingCtrl and iLoopFilterDisableIdc

Approved at: https://rbcommons.com/s/OpenH264/r/330/
1. update the default value of iLoopFilterDisableIdc as 0. In order to get the better quality, it is better to turn on deblocking filter
2. update the default value of bPrefixNalAddingCtrl as false. For NAL 14 is SVC NAL type, not AVC. but when the user only sets base parameter, we should remove this NAL type.

3. update hash code because the default values change.
