libroot: remove delete_driver_settings

It is not present in BeOS R5 and it just call unload_driver_settings.

Replace delete_driver_settings usages with unload_driver_settings.
Keep the symbol on x86 for binary compatibility.

intel partition map: implement changing the active partition

Implement the needed parts in both the userland add-on (loaded in
DriveSetup) and the kernel side one (used by disk system manager in the
kernel).

This allows changing the active partition in DriveSetup.

64-bit compilation fixes for write_overlay and intel partitioning system modules.

partition_module_info::uninitialize(): Added block size parameter for
convenience.

* Added optional partition_module_info::uninitialize() hook. It is supposed to
destroy the partitioning system's on-disk structure.
* Adjusted the existing partitioning system implementations accordingly.
Actually implemented the hook for the intel partitioning system.
* Added Uninitialize() method to KDiskSystem and KPartitioningSystem. The latter
implements the method calling the new module hook.
* _user_uninitialize_partition(): Also let the disk system uninitialize the
on-disk structure.

This fixes the failure to initialize a disk device with BFS, when it contains a
valid partition map with at least one partition.

Patch by Bryce Groff with changes by myself:
* Added missing name parameter to the partitioning system module child creation
and child creation validation hooks. Pass the name to them.
* Added BPartitionParameterEditor interface, which is/will be used for editing
disk system specific parameters.
* Implemented partition parameter editors for BFS initialization and Intel
partition map child creation.
* Fixed the incorrect supported child partition type iteration in the Intel
partition map add-on. It does now return actual types.
* Handle the "active" flag parameter in the Intel partitioning system module.
* DriveSetup:
- Replaced the "Create" submenu by a simple menu item. The type can now by
chosen in the dialog.
- Make use of initialization and child creation parameter editors. Some
non-generic code has been moved to the respective editor implementations
(BFS, intel partitioning system).

Added offset and size parameters to create_child_partition() and
KPartition::CreateChild(). CreateChild() calls AddChild(), which publishes
the new partition, though at that point offset and size were not set, so that
the published devices would not be usable.

* Removed SECTOR_SIZE in the read-only part of the intel partition scanner;
however, it's still used in the write part.

iPod so far, and it recognizes its partition fine now. Next test on real

partitions from the disk device manager.

* The shadow_changed() FS and partitioning system hooks take an
additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

* Added the partition size as parameter to the file and partitioning
system initialize() hooks. It's often the only info about the
partition one needs and thus locking the partition just to get it is
no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.
