e2c6ed87ec Fix several semantic bugs: 
- Always allow RAW_PART to be opened, regardless of the partition table.
- Never do partition translation on RAW_PART; it's always offset 0.
- Always make sure the disklabel is read from RAW_PART.
- Make *strategy() return values consistent.

This fixes a condition where a bogus partition table could be written
to the disk from SYS_INST, and the user had no way to rewrite with
a correct partition table, since RAW_PART would be invalid.

b71e65949f Make clock an early configuration device, configured before early console 
configuration. This way, the delay loop is calibrated before graphics and
serial hardware is touched.

This change should smooth pr 2890 by Thorsten Frueauf (also privately
reported by Laurent Badoukh). While the real problem with those is the
paranoically high delay() calls in the grf_cl initialization, it was made
even more visible by the miscalibrated (to the save side) new style delay
loop.

838edf78fd Snapshot of new config for NetBSD/hp300. This isn't quite finished yet. 
We're about 75% there.  SCSI and HP-IB are not yet supported in a new
config kernel; some autoconfiguration hackery has to be done there, yet.
These changes are enough to network boot a diskless kernel.

New config glue is enabled with the "NEWCONFIG" kernel option.  If that
option is not present, an old config kernel will be built.  Any kernel
configured with config(8) will automatically pick up the NEWCONFIG
option from std.hp300.

de3b8c8e4b Implement an rtc-device. Credits for the idea goes to Wolfgang Solfrank. 
Because there is no way yet to tell init(1) to execute commands before
single user-mode is entered, the inittodr() function is still partly
functional. It retrieves the value of the RTC and sets the time as if
the RTC was running at UTC. The resettodr() function is a No-Op. The
RTC can only be changed by a write to /dev/rtc.
The TIMEZONE and DST options are no longer needed and removed from the
config files.

693a05816e disable weak aliases in libc until something actually uses them. When 
using __weak_alias in libc, __indr_reference should probably be defined
to do nothing (but defined, so that duplicate functions/variables aren't
compiled).  However, when not using __weak_alias, __indr_reference causes
them to be omitted completely, which is a lose.  So, until weak aliases
are going to be used, don't define __weak_alias or __indr_reference.

af2691cdb5 The original docs for the Phase 5 Development SCSI boards had a edito, 
making me think that the Blizzard-IV and the Blizzard-2060 scsi
options have nearly identical DMA engines (just with a different
address offset). Alas, this isn't true.

Herewith I replace the "bznsc" (all-new-Blizzard-models) driver with the
"bztzsc" (Blizzard Two Zero).

0e3d6291e3 note what each of the argument registers in setregs() will be used 
for by crt0.  Actually clear a1 and a2, because unless a shared loader (i.e.
_not_ the kernel) set them when invoking crt0, they should be zero, and
the kernel DEBUG code wouldn't necessarily have them be.  Pass a pointer
to the proc's ps_strings structure in a3.

96acdadef7 First step inn removing config_scan() and the hacks that gave devices 
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
