according to 8.4.4.2.3 of JCTVC-L1003_v34,we need filter the neighbouring sample in two ways, but this is missing

accodding to 8.5.3.2.7 of JCTVC_L1003_V34 , the location of colPb need align with 16, but this is not corrected on HM-10

When I was compiling the source files with ndk-build​http://developer.android.com/tools/sdk/ndk/index.html, I found a problem of function initSigLastScan in TCommon/TComRom.cpp by keeping logs.

  if( iWidth > 4 )
  {
    UInt uiNumBlkSide = iWidth >> 2;
    UInt uiNumBlks    = uiNumBlkSide * uiNumBlkSide;
// Uint log2Blk default(-1) + 1 -> 0, but it becomes 256 in my compiler.
// So I suggest that log2Blk's type be fixed as Char.
// My Android app broke down because of this.
    Char log2Blk      = g_aucConvertToBit[ uiNumBlkSide ] + 1;
