I think everybody generally agrees that sharing code is good, and we 
should take opportunities to do so.

Where it's likely to get complicated is in areas like stop handling.  
GDB's native code can make casual references into breakpoint 
definitions, set/show variables, which is no big deal when you're in the 
same address space, but GDBserver needs to be either be preloaded with 
that information or pass the buck to GDB.

One thing that we could be doing in addition to moving code is to 
scrutinize gdb/*-nat.c and friends, and abstract out some API for any 
in-GDB-itself assumptions.  Hopefully that will help to minimize the 
need for #ifdef GDBSERVER hacks as we refactor the code.
