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.

* Moved devfs from fs/ to device_manager/, and separated the legacy driver
support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
- legacy SATA and ISA IDE support is disabled, the drivers haven't been
ported yet.
- The not yet used ATA bus manager hasn't been ported yet, either.
- AHCI changes have not been tested.
- the listdev command has been removed from the build (as it currently
doesn't work anymore).
- device manager generated IDs currently are not freed anymore when a device
node is removed.
- generic drivers can't yet use the new driver architecture.
- simple busses that do not support device types won't work yet.
- legacy driver publishing/unpublishing (ie. what USB needs) has not been
tested, and may be broken.

* scsi_cmds.h declared several variables instead of naming enums.
* the CD-ROM standard retrieval was broken (always checked index 0).

This improves abstraction and allows bus drivers that are independant of ide_adapter.

* Implemented the functions needed by ideinfo/idestatus using this one.
* The IDE bus manager now disables DMA if the safemode settings ask for this.

complicated to get a pci_info for a given pci_device before. The
function is not very efficiently implemented, but I didn't see how to
do that without more intrusive changes.

Also renamed some defines and structures, although the structure and some other names are still odd.
This module should probably be moved into the kernel anyway, as it provides basic and crucial services.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12646 a95241bf-73f2-0310-859d-f6bbb57e9c96
is now device_attr, pnp_bus_info bus_module_info, pnp_driver_info driver_module_info, ...
Small cleanup (more would be needed, but this has time).

is a work in progress; the name as well as the contents will change :-)
