Add a new REF_CREATE_ONLY flag for use by the files backend which will
only update the symref if it doesn't already exist. Add the possibility
to pass extra flags to refs_update_symref so that it can utilize this
new flag.

I'm not sure we need a new flag to do this as it is already supported by
the ref transaction api.

Thanks, I was not aware of ref_transaction_create. It also seems to return with
TRANSACTION_NAME_CONFLICT so we should be able to see from the error code if
indeed the existence was the problem or something else went wrong.

Thank you for working on this, and thanks, Phillip, for a useful
suggestion.
