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.

* Try at solving bug #6036; similar to Linux, we now try to cut down the
capacity by trying to read at the end of the medium.
* Not tested at all yet.

Enabled the IOCache depending on the amount of free pages. Currently the
limit is 180 MB.

Renamed IOScheduler to IOSchedulerSimple and pulled an interface IOScheduler
out of it.

Optionally use the IOCache instead of the IOScheduler (specified by
USE_IO_CACHE macro in the header). Currently disabled, though. It works fine,
if the machine has a good deal of RAM. I tested with the anyboot CD -- the
boot and installation times drop dramatically. On machines with little RAM
there are issues, though. Apparently the cache isn't drained fast enough, so
that other allocations can fail.

* Renamed src/system/kernel/device_manager/io_requests.{h,cpp} to
IORequest.{h,cpp}.
* Introduced public <io_requests.h> header. Currently it only declares the
single function BFS uses.

* Replaced the B_BLOCK_DEVICE_* defines with B_DMA_* defines that better match
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.

* This should have been part of r26828, although it did not break the build :-)

Renamed the "blkman" module to "block_io".
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.
