06da81f012 Implement node monitoring in the kernel disk device manager.
* Added {Create|Delete}Device() analogous to {Create|Delete}FileDevice
* Added a small DeviceWatcher class that reacts to entry creation/removal
* Implemented a way to start/stop node monitoring
* Start watching for devices after the boot volume has been mounted and the
  the second initial scan was run

The disk device manager now creates and scans a device when a "raw" node is
published and deletes the device on removal. This makes hot-plugging of disk
devices (for example memory sticks using usb_disk) work. Their partitions will
be scanned and published so they can be mounted. Somehow the removal of the
partitions does not yet work however, any insights are welcome.

7333992516 On a media change, the KDiskDevice must do a bit more than it did:
* it now updates the partition data,
* the flags,
* and the disk geometry - and that now allows the session add-on to actually
  detect a newly inserted CD.

88ef411154 * Added an UninitializeMedia() method to KDiskDevice that also resets the
device geometry.
* If SetTo() reports no media, and GetGeometry() fails, the device geometry
  is now reset as well.
* KDiskDeviceManager::_ScanPartition() no longer unmarks the partition busy;
  this is now done by the caller, and done independently from the outcome of
  _ScanPartition(). This also fixes the problem that devices with no media
  were never marked unbusy (and thus were ignored subsequently).

b3a5629b9e 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.

c9830ce0f5 * KDiskDeviceManager::{Find,Load}DiskSystem() can also find the disk
system by pretty name (not only module name) now.
* _user_initialize_partition() loads the disk system by pretty name.

7b45b55be1 * Added back and partially reimplemented the
K{Disk,File,Partitioning}System writing methods. It is now required
  that the caller has marked the concerned partitions busy, hence we can
  (read-)access them without needing a lock. The module interfaces will
  will be changed to take advantage of the fact as well. The methods take a
  disk_job_id instead of a KDiskDeviceJob* now, though I haven't quite
  decided, whether we need it at all or just want to add a special
  handling in the cases where notifications during the operation make
  sense.
* Reimplemented the disk device write support syscalls (save
  _user_move_partition() for which other module hooks are needed). They
  call the KDiskSystem methods, now.

327887959e * Moved partition scanning back to KDiskDeviceManager. ATM only
synchronous scanning is supported.
* Removed the disk device job support from the disk device manager.
* K{Disk,File,Partitioning}System:
  - Remove querying and validation methods.
  - Commented out the modification methods until their fate is decided.
* Removed obsolete _user_get_partitionable_spaces().

  have to be rewritten completely.
* Implemented the userland disk device jobs.

e544dd5915 * Fixed a possible dead lock between the kernel daemon and the DDM; the media
status checker now only tries to lock the manager, it won't wait anymore.
* Added MediaChanged() and UpdateMediaStatusIfNeeded() methods to KDiskDevice.
* KDiskDeviceManager::_CheckMediaStatus() now uses these new methods; it should
  no longer detect removed media more than once :-)

is dump its findings, but it's an (untested) start.

bf95c9aee6 * 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.

db5c68ca46 * 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.

76a8ec23db * Added disk system flags for whether a partition name and partition
content name are supported.
* Added file_system_module_info::flags (analogously to
  partition_module_info::flags) which indicate which disk device
  features the FS supports.
* Replaced the
  file_system_module_info/partition_module_info::supports_*()
  hooks by a get_supported_operations() hook and for partitioning
  systems additionally a get_supported_child_operations() hook.
* Updated file and partitioning systems accordingly.
* Updated fs_shell accordingly.
* Updated the DDM accordingly. The syscall interface remains unchanged,
  though.
* _user_supports_initializing_partition() also checks whether the parent
  partitioning system is content now.

65bd831cbb * KDiskDeviceManager::_ScanPartition() can now run synchronously (and execute the
scan job in the calling thread).
* KDiskDeviceManager::InitialDeviceScan() now runs synchronously, so that
  get_boot_partitions() doesn't need to do this ugly wait hack.
* KDiskDeviceManager::CreateFileDevice() can now run synchronously as well, which
  fixes a deadlock in fs_mount() - note, mounting file devices still doesn't work,
  though as Haiku's BFS doesn't allow this right now.

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
  declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
  explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
  something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
  'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
  is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
  Otherwise the an inner class with that name is considered as friend.
  gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

47f39c93cb Merged the disk device manager module interface for file systems with the

As a side effect, the automatic file system detection may now work (not yet
tested, though).
