Disk Device Manager: generate a name for nameless volumes

This will give the same result as fs_stat_dev, so the filesystems will
have the same name everywhere.

* The BMutablePartition setters adjust the change flags accordingly.
* PartitionDelegate::Uninitialize() uninitializes the mutable partition.

We need flags to track what properties of the partition change.

Decided that BPartition::ImmutableDelegate would basically be a big
collection of no-op methods, which could as well be implemented in
BPartition itself. This makes the Delegate hierarchy unnecessary:
MutableDelegate becomes Delegate, and we save a few casts as a side
effect.

* Initialization of BPartition::Delegate is now two-phased. The first phase
builds the object hierarchy, the second will (in case of MutableDelegate)
let the disk systems do their initialization. This way the disk systems
already find a fully functional object hierarchy they can work with.
* Child creation also takes a partition name as a parameter, now.
* Implemented BMutablePartition child creation/deletion.
* The BDiskSystemAddOn/BPartitionHandle::Validate*() methods return a
status_t instead of a bool, now.
