Minor Bug

Changes to TComSlice.h required in order to compile with GCC 4.8.1

When compiling with GCC 4.8.1 TComSlice.h is flagged up multiple times with a single compiler error ("array subscript is above array bounds").

In effect, the compiler does not like it that tLayer (or tlayer is is called elsewhere) is assumed to be valid, it could be abused and thus unsafe.

To resolve this fear, test tLayer against getMaxTLayers to decide if it is safe prior to accepting or reverting to the maximum possible value. e.g.

m_numReorderPics[(tLayer = tLayer > getMaxTLayers ()? getMaxTLayers () : tLayer)] = v;

Making the following modifications will suppress these errors and the codebase will compile.
