qcow2: List autoclear bit names in header

Browse source 
The feature table is supposed to advertise the name of all feature
bits that we support; however, we forgot to update the table for
autoclear bits.  While at it, move the table to read-only memory in
code, and tweak the qcow2 spec to name the second autoclear bit.
Update iotests that are affected by the longer header length.
