[Qemu-block] [PULL 24/85] specs/qcow2: do not use wording 'bitmap header' |

From: Vladimir Sementsov-Ogievskiy <address@hidden>
A bitmap directory entry is sometimes called a 'bitmap header'. This
patch leaves only one name - 'bitmap directory entry'. The name 'bitmap
header' creates misunderstandings with 'qcow2 header' and 'qcow2 bitmap
header extension' (which is extension of qcow2 header)
