On Darwin domain.sh JBOSS_BASE_DIR isn't resolved properly

In the following code in domain.sh all "cd ${p#=} ; pwd -P" should be "cd ${var#=} ; pwd -P"

=========================

1. No readlink -m on BSD
   if $darwin; then
2. consolidate the host-controller and command line opts
   HOST_CONTROLLER_OPTS="$HOST_CONTROLLER_JAVA_OPTS $@"
3. process the host-controller options
   for var in $HOST_CONTROLLER_OPTS
   do
   case $var in
   -Djboss.domain.base.dir=*)
   JBOSS_BASE_DIR=`cd ${p#*=} ; pwd -P`
   ;;
   -Djboss.domain.log.dir=*)
   JBOSS_LOG_DIR=`cd ${p#*=} ; pwd -P`
   ;;
   -Djboss.domain.config.dir=*)
   JBOSS_CONFIG_DIR=`cd ${p#*=} ; pwd -P`
   ;;
   esac
   done
   fi
