Kyle Evans c4a0333b55 vt: restore tty when console is ungrabbed ... When a break-to-debugger is triggered, kdb will grab the console and vt(4) will generally switch back to ttyv0. If one issues a continue from the debugger, then kdb will ungrab the console and the system rolls on. This change adds a perhaps minor feature: when we're down to grab == 0 and if vt actually switched away to ttyv0, switch back to the tty it was previously on before the console was grabbed. The justification behind this is that a typical flow is to work in !ttyv0 to avoid console spam while occasionally dropping to ddb to inspect system state before returning. This could easily enough be tossed behind a sysctl or something if it's not generally appreciated, but I anticipate indifference.
