7263209ce6 Make each disk and tape driver define its own read and write functions.
Deprecate rawread() and rawwrite() completely.  Remove d_strategy from cdevsw to
force the abstraction barrier.

e7356e6993 Use proc pointer passed in uio rather then curproc for credentials (should

644f409712 Properly initialize the credentials fields in the buffer used in physio().
Actually use the credentials of `curproc' when doing IO (among other things,
this allows us to read /dev/drum when swapping on an NFS mounted file).

0e6cb953ea ANSIfications - removed all implicit function return types and argument
definitions.  Ensured that all files include "systm.h" to gain access to
general prototypes.  Casts where necessary.
