fish: fuse: Add -m dev:mnt:opts to allow mount options to be specified.

This lets you turn on ACLs and xattrs by doing:

  -m /dev/sda1:/:acl,user_xattr

The extra parameter is passed through to mount_options:

  libguestfs: trace: mount_options "acl,user_xattr" "/dev/sda1" "/"

-Using this flag is mostly equivalent to using the C<mount-options>
-command or the C<mount-ro> command if the I<--ro> flag was given.
+The third (and rarely used) part of the mount parameter is the list of
+mount options used to mount the underlying filesystem.  If this is not
+given, then the mount options are either the empty string or C<ro>
+(the latter if the I<--ro> flag is used).  By specifying the mount
+options, you override this default choice.  Probably the only time you
+would use this is to enable ACLs and/or extended attributes if the
+filesystem can support them:

+ -m /dev/sda1:/:acl,user_xattr
