Changes to let the Alpha DDB code build in user-space for crash(8).

Adjust proc/lwp access for user-space (crash(8)).

Refactor the special symbol handling out of db_trace.c into
db_interface.c, and abstract it away from having to read kernel
symbols directly.

ddb: New db_stack_trace_print_ra.

Takes an optional extra argument for the return address so that the
stack parser has a chance to use instruction-dependent interpretation
of the frame to find parent frames.

Implemented only on Alpha for now, which needs it.  Other
architectures just ignore the extra argument.

update from HEAD

Cleanup and clarify the ELFSIZE mess:

We now have 2 variables automatically set in elf_machdep.h:

    ARCH_ELFSIZE: the size for userland binaries
    KERN_ELFSIZE: the size for the kernel binaries

DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the
same values DB_ELFSIZE used to have.

In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE
for the kernel and ARCH_ELFSIZE for userland. These defaults should
eliminate the need for most manual ELFSIZE setting.

Introduce DDB_EXPR_FMT and replace the logic around DB_EXPR_T_IS_QUAD.

- move sched_changepri back to kern_synch.c as it doesn't know PPQ anymore.

Replace the Mach-derived boolean_t type with the C99 bool type.  A
future commit will replace use of TRUE and FALSE with true and false.

closes: PR kern/32359

modifies machine/db_machdep.h: BKPT_SET(inst) to BKPT_SET(inst, addr) for all archs ie; passess the
breakpoint address as well.

Patch from cherry@mahiti.org

Add a BKPT_ADDR() macro which gives MD code a chance to munge a
breakpoint address before it's used. Currently a no-op on all but sh5.

This is useful on sh5, for example, to mask off the instruction
type encoding in the bottom two address bits, and makes it possible
to do "db> break $rXX" instead of manually munging the address.

Catch up to -current.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

After reviewing the Green Book, BPT traps do indeed leave the PC pointing

More DDB support:
- Add support for software single-stepping (Alpha does not have hardware
  support for single-stepping)
- Alpha uses Elf64 symbols.

sync the nwscons branch up with yesterday's version of the trunk.
Lots of conflicts/changes because of the RCS Id format changes.
Also, a few cleanups and corrections.

clean up NetBSD RCS ID strings

FIXUP_PC_AFTER_BREAK now takes an arg of type db_regs_t *

Instead of treating the trap/syscall/exception frame like a struct
containing a substruct (the hardware frame) and an array of registers,
treat it like one big array of registers, for easier and prettier
access.  Update everything to deal with that.

wholesale update from my NetBSD/Alpha source tree.  Includes:
	Support for AXPpci CPUs,
	Support for AlphaStation 600 CPUs,
	new boot block structure, which requires an 'installboot'
	    program and works a lot like the NetBSD/sparc boot blocks.
