- Store changes to the selected swap-choice when the combobox changes
- Use that member instead of dereferencing the combobox
This avoids nullptr crashes when the combobox isn't even created
(e.g. when there is only one swap choice).
When chosing the "Replace partition" option, free space is not handled
like any partition. In order to apply the custom partition layout in
that case too, we have to modify the code where "replace free space" is
handled.

In some cases where a custom partition layout is used, use of this
layout is mandatory (this can be the case when using a read-only rootfs
which is updated by block-cpying an image file to it).
For these cases, the user must not be able to change the partition
layout, therefore we have to disable manual partitioning.
In order to stay consistent with current behaviour, manual partitioning
is still enabled by default. It will only be disabled if the partition
module's config file contains the corresponding option set to "false".

When choosing "Install alongside another system", the custom partition
layout is applied to the space freed by resizing the selected partition.

Suggested by aliveafter1000: having a default value, and then
filling in the default in one place it is used and not others,
is weird. Instead of dropping the one use, remove the default
value: partition flags are important enough to be explicit.
- The choice of swap needs to be handled in more places,
so make the enum available in the partition module core instead
of just inside the choice page.
Scenario is this: you have no suitable installation devices on
your system (everything is mounted, or HDD has died), click through
to partition page, where you have all the buttons available, but no
devices in the list. The following actions then cause a crash:
- clicking "back"
- clicking any button
Prevent that:
- you can click "back", but if there is no device selected
nothing happens to the device state (no nullptr deref,
and no crash)
- button code is now more resilient to this scenario
- buttons are hidden until a device is available, so you
can't even click on them to trigger the code.
- deleteLater() doesn't like nullptr (produces a warning, but is harmless)
- reparenting across threads doesn't work, comment on that but leave
it in, since this may be relevant for memory management.
