maint: Clean up #includes in liboctave/numeric directory.
* build-aux/mk-opts.pl: Change Perl to generate "" around local include
libraries rather than <>. Include "lo-math.h" rather than <cmath>.

Rationalize #includes. Use forward declarations of just classes where
possible. Reformat some long lines < 80 characters. Reformat some comments
for readabliity.
* mx-inlines.cc: Rationalize #includes for this file in liboctave/operators
used by many in liboctave/numeric.
