Revive security/wpa_supplicant after 6.5 years => version 2.3

This port was retired at version 0.3.8 because wpa_supplicant is
part of FreeBSD base.  However, the last few releases have had a period
of only a few months, so the base is always going to be behind.  DragonFly
is also affected, so I'm bringing the port back at the latest version.

It features the same patches as FreeBSD including the conversion to use
libutil's pidfile routines.  There are some additional patches for
DragonFly support and to fix some bugs from the 9 Oct 2014 release.

The WPA Supplicant build system has been converted to ports options, and
there are dozens of them.  I've set the defaults to match the
configuration in base and verified that it builds with all options
selected at once.

Add "auto-accept" to LICENSE_PERMS.

It is not entirely clear to me what the policy is to decide whether a
license can be auto-accepted, but for now this makes it possible to build
the port without supervision (eg. with BATCH=1).
