Use the i/o handle for the `delay port' exported from the parent
ISA bus, rather than the totally bogus combination of [ioh, 0x84].
Also, fix a bug apparently introduced when the -Wall changes were checked
in which, under most circumstances, would cause a 16-bit WD8013EP to
be mis-identified as an 8-bit WD8003EP.
This removes the need to have enough chip memory to load the kernel
when booting. Kernel memory is dual-mapped (VA == 0 and VA == PA)
for enabling the MMU, and the VA == PA mapping removed after start_c()
has completed. Chip memory is still required for the /dev/reload
process.
Startup modified to work with kernel loaded directly into fast memory.

loading into fastmem. This removes the requirement that the kernel fit
into chipmem.
Add a -Z flag to force loading into chip memory.
Add a -s option for compatibility with my bootblock loader.
Move the test exit to just before starting the kernel; this lets the
test mode actually load the kernel and do the version checks.
Thanks to cgd@NetBSD.ORG for pointing the following out to me:
listen (fd, SOMAXCONN); would break.
As programs wouldn't see the changes that might be specified in
the kernel config file.
As penance I am going to see if it would be possible to move this
into param.h and provide away of finding out what the kernel
value is. On busy network servers this value is useful to have as a tunable
kernel parameter.
handling code so that if a given interrupt is disabled (and therefore
can't have caused the actual I/O interrupt), its handler won't be
called even if its bit is set in the interrupt register.
