Partially revert 4be83cc2b28ea09aa8ff789839e6520df60836f8

Browse Source 
The above commit did two things:

 1) A number of functions were renamed and made nonstatic.
 2) A number of other functions were renamed only.

This commit reverts #1 but not #2.  In addition, prototypes for
functions now remade static have been removed from i386-dregs.h.
