Make api.xml more consistent with the plplot.h header.  These issues
were all discovered by a consistency checker written by Hǎiliàng Wang.

Tested by Alan W. Irwin <airwin@users.sourceforge.net> using the
"make validate" command.

ToDo: The checker found ~10 functions in the public API of PLplot that
are undocumented in api.xml.  At least one of those (plwid) is
deprecated so some conditional programming using the PL_DEPRECATED
macro should be used to eliminate that function (and any other
officially deprecated function) from consideration by the consistency
checker.  Also, some of those ~10 functions will actually need to be
documented in api.xml to provide a clean checker report.
