Lowly Worm 30264306a0 Make function to allow grabbing the flags by order of importance in flagspace ##core
* use relsub addr
* kill i2, grab top of list when not in preferred spaces
* Add r_core_flag_get_by_spaces
* Remove r_flag_get_i2 and use r_core_flag_get_by_spaces
* Fix fcn name from flag
* Better consistency: flag_get instead of get_flag
* Quickpath for just one flag
