Visual Studio builds: Allow silencing deprecation warnings

Browse Source 
Define XML_IGNORE_DEPRECATION_WARNINGS and the corresponding XML_POP_WARNINGS
for Visual Studio, and consequently define XML_IGNORE_FPTR_CAST_WARNINGS so
that we do not get a compiler warning on Visual Studio by doing a
__pragma(warning(pop)) without a corresponding __pragma(warning(push)).

Also correct the documentation a bit for XML_POP_WARNINGS.
