but doesn't really do anything more than before.
* It also replaces everything IDE with ATA counterparts and cleans up a lot
of the definitions.
* Cleaning up the old ATA bus_manager as well as some license headers missing.

ide_mask_sector_count_48, and ide_mask_LBA_*_48 were all wrong.
* Using the high byte in LBA48 mode should work now, too (wasn't written
to the IDE controller before, but that shouldn't have been a problem yet with
today's disks).

our dma_restrictions structure (but we're using blocks instead of bytes,
since unlike the block size, the restrictions attributes are constant).
* We might want to use blocks for the dma_restrictions structure as well in
the future...
* Fixed another bug in the device_node variant of DMAResource::Init(): the max
segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.

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.

again.
* Publish /dev/ptmx. Opening it will open a fresh pty master. In
principle /dev/pt/ is obsolete now, but I guess we keep it around for
compatibility with BeOS. Though there shouldn't be many applications
opening a pty, that we might be interested in...
* New ioctls B_IOCTL_GET_TTY_INDEX (returns the tty index) and
B_IOCTL_GRANT_TTY (grants tty slave access rights).

Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).

actually forgot to commit the changes I made to the ide_adapter...
* the IDE bus master command/status stuff is now used via flags; it's no
bitfield anymore.
* Changed a few constants to upper case.
