Actually, some of my internal co-workers are so allergic to changes in gdbserver
that I would rather do something in the patch. [Thinking out load].  Adding more
overhead to the traffic over the wire cause a couple of other developers heartburn.  It
would also mean writing code to do essentially the same thing as the *_command
function because it already parses the string and then calls symbol_file_add.  Since calling
that function isn't what is wanted from an architectural perspective, why don't I "copy" the
code to remote.c (renaming the function in the process) and then then symfile patches
won't be needed and the code should be about the same size.

Ok, I can agree.  Now that you have convinced me, how do I do it.  The reason that I
coded the switch was because I couldn't figure out how to add a command that would only
get used in the remote code.
