[Libguestfs] [PATCH] fish: Add --rw option (does nothing yet).

This patch is meant for discussion of the issues involved. I'd like to change the default for guestfish -a / -m command line options to open read-only. This creates less opportunity to corrupt disk images by opening them for write while another VM might be using them. With this patch you can specify: guestfish --rw ... which in itself does nothing since the default is currently read/write anyway. But it allows us in future to add a configuration file that controls the default ("default" being the case where you use guestfish or guestmount with neither --ro nor --rw options). We can then change the configuration file in 1.8 to make read-only the default. By backporting this patch to the other stable branches we can start introducing scripts that use 'guestfish --rw' in readiness for a future change to the default.
