Denys Vlasenko b28d4c3462 ash: [VAR] Move unsetvar functionality into setvareq 
Upstream commit:

    Date: Tue, 25 May 2010 20:55:05 +0800
    [VAR] Move unsetvar functionality into setvareq

    This patch moves the unsetvar code into setvareq so that we can
    no have a pathological case of an unset variable hanging around
    unless it has a bit pinning it like VEXPORT.
