Partially revert 4be83cc2b28ea09aa8ff789839e6520df60836f8
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. gdb/ 2014-06-19 Gary Benson <gbenson@redhat.com> * i386-nat.c (i386_dr_show): Renamed to i386_show_dr and made static. All uses updated. (i386_dr_length_and_rw_bits): Renamed to i386_length_and_rw_bits and made static. All uses updated.
