Add missing policies, modify toDense function

Added missing policies to cpy sparse matrix in dense matrix.

Added an optional parameter to toDense function in xGenericSparseMatrix: if zero fill==false, toDense does not reset the dense matrix to zero
before filling it. It can be used to fill a dense matrix blockwise. The default value of this parameter is true, so it does not change anything in
pieces of code which were previously using this function.
