* Implemented missing cleanup when an IOScheduler is destroyed. The threads
weren't terminated orderly.
* IOScheduler now stores its name and gets a unique ID.
* Added IOSchedulerRoster singleton which registers all IOSchedulers. It also
provides a notification service. We generate interesting events for
IOSchedulers, IORequests, and IOOperations.

* First baby steps in letting our drivers use the new I/O request/scheduler
architecture: for now, we do this on the lowest layer only, therefore all
requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
exporting a device on their own, and use an I/O scheduler with an appropriate
DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
of the previous read/write functions, moved preferred CCB size from those
functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
it); it's sometimes triggered by the code now, and I haven't yet looked into
the issue -- doesn't seem to harm, at least.

* Made block_io.h usable from C++ (which doesn't like "typedef a *a" anymore).
* Renamed scsi_dsk to scsi_disk.
* Joined all scsi_disk sources together to a single scsi_disk.cpp file.
* Cleanup.
