MueLu: print data in advanced xml mode (#2260)

James Willenbring requested to merge mayrmt:mayrmt-write-data-expert-xml into develop

Created by: mayrmt

Allow to print "Nullspace" and "Coordinates" to files from the advanced xml input deck.

Description

In the 'expert' xml interface (Tobias' style), the parameter list 'DataToWrite' controls output of quantities to files. Now, we can also print 'Nullspace' and 'Coordinates'. This has been available in the simple xml-file for quite a while.

Now, xml parameters for printing level matrices, prolongators, and restrictors are consistently named "A", "P", and "R". A deprecation warning is issued if the advanced xml input uses its old parameter names.
