overflow in RDOQ for 14-bit coding

Description

As described in JCTVC-I0108, 14-bit coding issues were suspected. The problem (mainly) comes from RDOQ variable overflow for 14-bit coding. This has been tested and it is fixed by the proposed patch (about 4.5% coding gain for 14-bit coding that makes it consistent with 8, 10, 12 -bit coding gain).

Suggestion of a straightforward new patch on top of HM-7.1-dev r2483 in order to fix overflows for beyond 10-bit coding.
