 Add scandir() compatibility feature.

 This adds a wrapper to make the scandir() 'compar' argument and the
 provided alphasort() function match the types used in 10.8+, thereby
 avoiding warnings, and in some cases errors, due to the pointer type
 mismatch.

 To avoid breaking code expecting the old behavior, this hack is only
 applied when _MACPORTS_LEGACY_COMPATIBLE_SCANDIR is defined nonzero.

 Closes: https://trac.macports.org/ticket/70702

 TESTED:
 Tests pass on all OS versions with this fix.
