Minor changes to bsd.port.mk and bsd.pkgng.mk

[Cejka Rudolf]

Hello,
  what do you think about the following minor changes to bsd.port.mk
and bsd.pkgng.mk? The motivation is that it is currently relatively
hard to detect, which options of a port are locally changed by user,
or by gradual port upgrades with OPTIONS changed by port maintainer.
(With consequence that when upgrading ports using packages and there
is some non-default options value in a port, direct port compilation
should be forced instead of use of a package.)

Some port maintainers do not use on/off, but they use values ON/On/OFF/Off.

I think that curent default value detection in make showconfig is useless
and confusing, and it should be better to detect real value difference
among OPTIONS in Makefile and options is /var/db/ports.

Furthermore, it is possible to define WITH_* and WITHOUT_* variables
in environment, so maybe there could be even bigger checks for on/off.
