Justin Lebar 051c5b560a Bug 802686 - s/MOZ_NOT_REACHED/MOZ_CRASH/ in Gecko. r=(see below)
r=tbsaunde for accessible
r=jmuizelaar for gfx
r=roc for layout
r=glandium for mozglue
r=jduell for netwerk
r=khuey for everything else

This is a mechanical change made with sed.  Later patches in this queue
clean up the whitespace errors and so on.
