  For some reason the "[Thread XXXX exited]" messages are not printed
inside thread.c from functions like delete_thread, etc as might be
expected.  Instead, each target seems to print the message before
calling delete_thread.

This doesn't seem ideal, and I can't help but feel that the printing
should be moved into thread.c, however, I have not tried to do that in
this commit, as I suspect there will be lots of fallout that needs
fixing up.

Instead, in this commit, I have added the printing code into remote.c,
so that the remote target will now correctly tell the user when a
thread has exited.

This fixes some test failures in gdb.threads/thread-specific-bp.exp
when run with the native-gdbserver and native-extended-gdbserver

When using the native-extended-gdbserver board I still see 1 test
failure, but I think this is not related to the issue fixed in this
commit, so I'm ignoring that for now.
