LGTM

One nit for discussion's sake.
CORE_ADDR for gdbserver is a native value, whereas in gdb it's a
target value.  That's why the static assert (sizeof (CORE_ADDR) >=
sizeof (void *)) isn't in common code (IIUC - e.g., consider a
64-cross-32 gdb).  I don't think that'll ever be a problem, and if it
does become one we can address it then.  Just thinking out loud ...
