Gary Benson 42995dbda6 Vectorize gdbserver x86 debug register accessors
This commit makes gdbserver access the x86 debug register accessor
functions via the same function vector as GDB proper.  This removes
a chunk of conditional code that was previously in i386-{nat,low}.h
and leaves a single macro as the only GDB/gdbserver difference in
nat/i386-dregs.c.
