exchange: pass includepats and excludepats as arguments to getbundle()

This will help in implementing narrow stream clones. Also narrow extension used
to add these arguments, now we add them by default if they are not empty.

Since reading includepats and excludepats on the server only works when narrow
is enabled, we check if narrow if enabled or not before passing them.
