08a2715e38 Test for serial console in adb_init() early, and abort if we're using it. 
Initiialize ROM vectors regardless of this so that the PRAM RTC read and
write work regardless of whether a serial console is in use.

a0222c1293 Turn on disconnect/reselect by default on targets 4-7 on the premise that 
tape devices normally are set to one of these targets. Tape devices should
be allowed to disconnect for the SCSI bus to operate acceptably.

0569d3582c Use the right microsecond delay address. To achieve this, also map that 
piece of hardware into kernel virtual memory (was only a guess 'til now).
XXX Unfortunately, the hardware vendor reserves the right to change this in
future DraCo revisions. We must rethink delay() and DELAY(), at least for the
DraCo, soon.

fc7c84da3a Explictly credit Per Fogelstrom for the mips shared library support in elf.c, 
which was taken from OpenBSD/pica.

The previous revision of elf.c replaced Ted Lemon's elf exec machinery
with something closer to Christos' MI elf machinery. It turns out
that old NetBSD/pmax elf binaries have three segments, and the newer
elf exec machinery cannot exec them.

The old elf exec machinery is folded back into cpu_exec.c, which falls
back onto using the old machinery if the new machinery fails. The
old-style binaries will be deprecated at the 1.2 release.

758ea43e99 Completely revamp setroot() and friends. Since Chris' version of this code 
is close to how I reworked it, I pulled in the (essentially MI) NetBSD/alpha
and added the appropriate support around it.

- No need for the GENERIC kernel config option.
- NFS-mounted root and swap are supported.
- If we can't figure out where the root filesystem is from what the Booter
  tells us, ask the user.
- Split the mainbus autoconfig code to a separate file.

Also, update/add copyrights as appropriate.

506cefab8c In the sync case of bwrite(), move the accounting earlier so that so that the 
delayed write is logically converted to a sync write, mirroring the async case.
In bdwrite(), move the tape case earlier to avoid needless reassignbuf()s.
