add physical_block_size field where applicable

only scsi_disk checks the actual value, other drivers take the logical block size.

This change reports the physical block size from the disk rather than the block
size used by IDE/SATA/SCSI commands. On typical modern SATA disks, the SATA
commands will use 512 byte blocks, but the disk will actually read and write
4K blocks internally. This is only of importance for partition alignment for DriveSetup,
and is independant of file systems or partitioning systems. This could also influence
the recommended block size for some file systems.

disk device manager: check that partitions are unmounted before uninitializing.

when uninitializing a partition or a disk (removing the partition
table), check that all partitions from that table are unmounted, as they
are about to become invalid.

Fixes #8827.

Changed {,u}int64 to be long rather than long long on x86_64.

More 64-bit compilation/safety fixes.

Add missing error return.

Reverted the part of r31520 that made devfs_unpublish_partition() take a raw
device path + child partition name. When a "raw" device is unpublished the node
removal notification triggers the partition and child partitions to be
unpublished/removed. Since in that case the "raw" node is already unpublished
trying to resolve it in devfs_unpublish_partition() again to unpublish the child
partitions would fail, leaving the child partition nodes behind. When a new raw
device would then become available publishing its partitions would fail because
of these left behind nodes, causing bug #4587. Seeing that this code is more
compact and straight forward anyway I don't quite see why it was changed in the
first place.

Patch by Bryce Groff, some changes by myself:
* devfs:
- devfs_[un]publish_partition(): They no longer get the partition path as
parameter, but rather the device path and the partition name.
- Added devfs_rename_partition(), which renames an already published
partition node.
* KPartition/KDiskDevice:
- Replaced the fPublished flag by fPublishedName, the name under which the
partition is published. This simplifies UnpublishDevice() and makes it
practically infallible.
- Added GetFileName(), which only returns the partition's file name.
Simplified GetPath() by using it.
- When a partition is added/removed the subsequent sibling partitions get a
new index. Now we also rename their published device nodes (and those of
their descendents). When something goes wrong we unpublish the concerned
partition's device to be on the safe side. Would be a shame to accidentally
format the wrong partition, eh? :-)

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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31463 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Publish the newly added child partition, not the (already published) parent
partition.
* Don't fail, if publishing failed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31460 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Bryce Groff:
* SetBusy(): Use AddFlags() instead of SetFlags() so that the other flags
aren't cleared.
* AddChild(): Publish the newly added child partition. Otherwise no-one can do
anything with it without rebooting first. Other children may need to be
republished under a new name, if their index changes, which doesn't happen
yet.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31444 a95241bf-73f2-0310-859d-f6bbb57e9c96

* KDiskDeviceManager::RescanDiskSystems() now also rescans all partitions with
the newly found disk systems.
* _ScanPartition() now allows to restrict the disk systems to a predefined set.
* _ScanPartition() now even scans partitions that already have a disk system
assigned; if a better one is found, the existing one is replaced. It will
ignore mounted or partitions with children, though.
* KPartition now also stores the priority of the disk system assigned to it.

* When removing a media, only the device was unmounted if needed, not its child partitions.
Not sure if this is the right place, Ingo might want to review that one.
* This fixes unmounting sessions of a multi-session CD, ie. the BeOS CD (it currently panics
when trying to access a device that's not there anymore - for debugging only, of course :-)

axeld + bonefish:
* Unmount when uninitializing a partition.
* Finished the media checker implementation, i.e. we rescan when a media
was inserted and uninitialize when ejected.
* Turned the disk device media checker from a kernel daemon into a thread.

descendants.

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.
