4e0c8707f7 To enable people to mount DOS partitions on disks with no NetBSD 
partition, add the MBR partitions to the default (faked-up)
disklabel used by NetBSD if it can't find a real one.  If the
type of the MBR partition is one of the common DOS ones, mark the
partition as having an MSDOS filesystem.

0b56afadf3 make this idempotent. bus.h needs to include it, and other things which 
may include something that includes bus.h may include it as well.

6826c7bf48 bus memory and I/O space access functions/macros, to be used by 
machine-independent code for more sane access to bus resources.
New functions will be added to this set, in the future, as appropriate,
but this is a good starting set.  Defines:
	bus_{io,mem}_{map,unmap}
	bus_{io,mem}_{read,write}_{1,2,4,8}
functions, and several types to go with them.

18ec26aa21 add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH, 
execpt without quotes.  meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).
