Silence warnings with GCC 5.4

Browse Source 
This fixes warnings like the following:

codec/decoder/core/src/mv_pred.cpp: In function ‘void WelsDec::PredPSkipMvFromNeighbor(WelsDec::PDqLayer, int16_t*)’:
codec/decoder/core/src/mv_pred.cpp:158:51: warning: ‘iLeftTopXy’ may be used uninitialized in this function [-Wmaybe-uninitialized]

codec/processing/src/backgrounddetection/BackgroundDetection.cpp: In member function ‘void WelsVP::CBackgroundDetection::ForegroundDilation(WelsVP::SBackgroundOU*, WelsVP::SBackgroundOU**, WelsVP::CBackgroundDetection::vBGDParam*, int32_t)’:
codec/processing/src/backgrounddetection/BackgroundDetection.cpp:281:63: warning: suggest parentheses around operand of ‘!’ or change ‘|’ to ‘||’ or ‘!’ to ‘~’ [-Wparentheses]

For the possibly uninitialized variables, this is similar to earlier
commits 8be8fe17 and af2666fd.
