Get rid of src/lib/common/land.c

Browse source 
There are several files with land unit subroutines.  This one is in an
awkward place: it depends on stuff from ../subs, which contributes to
libcommon.a's ugly dependencies.  Move its contents to logical places
(use internal linkage where possible), and remove it.
