Log Message:
Pull up following revision(s) (requested by mrg in ticket #1024):

        sys/ddb/db_command.c: revision 1.157
        sys/ddb/db_command.c: revision 1.158
        sys/kern/subr_lockdebug.c: revision 1.67

always call lockdebug_dismiss() from DDB -- there are always some
minimal lockdebug checks in place, even without LOCKDEBUG.

adjust lockdebug_abort() to ignore problems after ld_panic is set

so that there's a chance of this working.
this fixes ddb 'reboot' on softiron od1000.

call spl0() before cpu_reboot(), so that there's a chance that:
- interrupts can work afterwards
- this also means if IO stalls, serial break might work again.

this mimics how reboot(2) ends up calling cpu_reboot().
