Formatting extended partitions is not allowed,
and results in an error message. They have to be
deleted and recreated as primary partitions.

Hide the format action for partitions which are
only containers for other partitions,
i.e. extended partitions.

Growing the partition for offline resize caused
a rediscovery in UDisks to led to GVFs automount
which lets the Disks filesystem resize call fail.

A good solution is to keep the filesystem mounted
while growing the partition, as it is done in the
online resize already. This way there will be no
rediscovery and automount, and the filesystem can
be unmounted afterwards to be grown. From this point
there will be no automount coming because the partition
size is not touched anymore.

Same as on master except for only reusing translated
strings by taking shorter error messages.

The mount option dialog for editing /etc/fstab was
only shown for swap volumes if they were already
present in /etc/fstab.

Now the mount options are always accessible for
swap volumes. Their mount point is fixed to 'none'
because that is the only valid option, opts default
to 'sw' and type to swap. The irrelevant options
are insensitive.

The variable block_object was used as argument without
testing whether it is NULL.
