Math function usage fixes

Add using declarations and #includes where needed, and clean up some
unnecessary ones.  abs() is particularly annoying, as the int version
easily gets into the global namespace and doesn't give a warning if
used with floats or doubles.

Don't qualify potentially overloaded functions with the std namespace
