Mk/bsd.options.mk: Introduce SELECTED_OPTIONS, DESELECTED_OPTIONS

Browse Source 
Until now, the only way to obtain information on the valid port options
and the current selection states is by using the pretty-print-config
target.  It would look something like this:

  > make -C /usr/ports/lang/gcc5-aux print-print-config
  Standard[ +FORT +OBJC +NLS -TESTSUITE -ALLSTAGES -STATIC ] \
  Bootstrap[ -BOOTSTRAP ]

To process the total options and the selection state of each option
requires additional processing, e.g. with awk and/or sed.  Moreover, if
other information is needed about the port it question, it would require
a second execution of "make" to reveal variable values. There simply is
no other way to obtain the option selection information in a single pass
(this limitation came when options framework was brought in).

This enhancement allows the option selection information to revealed with
make -V so that all port information can be acquired in a single pass.
Moreover, they won't require piping through sed or awk.  Two read-only
variables are introduced:

  SELECTED_OPTIONS   (list of all "on" options)
  DESELECTED_OPTIONS (liss of all "off" options)

Here's an example of a single pass acquisition:

  > make -C /usr/dports/lang/gcc5-aux -V PKGNAME -V SELECTED_OPTIONS \
    -V DESELECTED_OPTIONS
  gcc5-aux-20150716
  NLS OBJC FORT
  BOOTSTRAP STATIC ALLSTAGES TESTSUITE

Obviously the grouping information seen in pretty-print-config is lost,
so these new variables will not help if option group information is
required.
