Allow some methods in Problem to use const double*.

Browse Source 
Some methods in Problem do not modify the parameter block
and those methods now allow the user to call them with const double*.

The methods are

RemoveParameterBlock
SetParameterBlockConstant
IsParameterBlockConstant
GetParameterization
GetParameterLowerBound
GetParameterUpperBound
