merge ktrace-lwp.

add a prom patch that creates a device node for the Krups' audio chip
in case it's missing ( like with OF 3.11.10 ) - makes audiocs at ebus work
on these machines.

branches: 1.17.2; 1.17.16; 1.17.18;
Add support for large kernels by searching for a physical memory segment
to fit it in. As a bonus, the kernel is now also mapped to the virtual
address (i.e. KERNBASE) it is linked at.

Increment version number for match function and Cycle 5 IP changes.

PROM patches for JavaStation-1.

Bump the version numbers of all bootloaders which use loadfile_elfXX() now
that it tries hard to avoid backwards seeks.

branches: 1.13.4; 1.13.6;
Bump version numbers of all bootloaders that use loadfile/ELF, to account for
my changes to symbol loading. I should probably have done this at the time,
but it's better late than never.

branches: 1.12.4;
switch to sys/conf/newvers_stand.sh for generation of version file
sync the message in boot/version with other ports using newvers_stand.sh

branches: 1.11.2;
Add bootinfo struct to pass symtab arguments.
XXX: This does not work with ELF yet, but I don't understand why...

Checkpoint of elf boot stuff:
- Use loadfile for both boot and installboot
- Fix problems with linking in bootxx
- Make installboot work with both a.out and ELF bootxx
- *WILL NOT BOOT YET ELF KERNELS* (a.out kernels work) I am working on it.

branches: 1.9.4;
look for /^Version:/ to find the boot block version, rather than using
the "version" file's RCS id (which is useless for branches).

add support for finding kernels other than `netbsd'. the list is:
netbsd, netbsd.gz, netbsd.old, netbsd.old.gz, onetbsd, onetbsd.gz
and vmunix, in that order. this is used by the bootable `bootfs'
image (suitable for floppies and cdroms), which contains a netbsd.gz
by default.
while i'm here, fix up `boot [device] -s' which got broke when
booting kernels with a - in their name was fixed..

branches: 1.7.8;

Completely rearrange SPARC boot code, modeling it after alpha and hp300
ports' boot programs. Also added support for loading gzip'd kernels,
useful for booting from floppy. From Jason R. Thorpe <thorpej@nas.nasa.gov>,
tested by Matthew Green <mrg@eterna.com.au> and Erik Fair <fair@clock.org>.
