Renamed RELOOKAHEAD -> LOOKAHEAD, REGBMAP -> LOOKGBMAP

Browse Source 
Yeah, after using these for a bit, the RE* names were not great.

Trying LOOK* now, as an alternative that hopefully still implies the
similar behavior without needing an additional prefix for LOOKAHEAD:

- LFS3_*_RELOOKAHEAD        -> LFS3_*_LOOKAHEAD
- LFS3_*_REGBMAP            -> LFS3_*_LOOKGBMAP
- cfg.regbmap_thresh        -> cfg.lookgbmap_thresh
- cfg.gc_relookahead_thresh -> cfg.gc_lookahead_thresh
- cfg.gc_regbmap_thresh     -> cfg.gc_lookgbmap_thresh
