where the floppy driver would wedge because a motor-on timeout would
be cancelled by another I/O operation cancelling a motor-off timeout.

* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
make them type-generic, which is necessary i.e. to operate on file offsets
without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
integral type (paddr_t, vaddr_t).
Originally done by Chuck Silvers, updated by myself.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
* do not require a `zs' driver for console handling
* run the console on PROM primitives until a device recognises
itself as a console device during normal autoconfiguration.
* allow (keyboard) devices to take over the input channel of
the PROM primitive-based console device.
As a result, consinit() is much simplified and does no longer have
to "detect" devices to setup a working console device. This complexity
has moved to individual drivers which interpret the PROM information
after they have attached to decide whether or not to act as a console.
so that the right entries get added to dev_name2blk[]. Needed for / on RAID.
(Whoops! I missed checking these in when adding the RAID_AUTOCONFIG stuff.)
tctrl now initializes the state of the internal LCD icons. The icons
are unprogrammed at boot time. This incidentally makes the DC-POWER icon
work.
Fixes:
Fix my stupidity in the ENVSYS stuff, and actually follow the API.
