Improved implementation of PreparedStatement.getParameterMetaData(). The previous implementation created a new ParameterMetaData object each time this method is called which is quite costly if it is called from inside a loop. As the ParameterMetaData is static for a PreparedStatement it is better to create it once, cache it in the PreparedStatement object and return the cached object for next calls to PreparedStatement.getParameterMetaData(). We also now create dedicated 1-based meta data arrays, such that we no longer have to call getParamIdx(param) in methods of ParameterMetaData.
