fdo#70000 add support for COVARIANCE.P and COVARIANCE.S functions
These functions have been introduced with Excel 2010, but were not
supported yet in calc.
COVARIANCE.P (population) replaces the COVAR function, but the COVAR
function remains present (in Excel as well as in calc).
COVARIANCE.S (sample) is a new function.
