qemu-iotests: add 036 autoclear feature bit test This new test validates the autoclear feature bit behavior. When QEMU opens a qcow2v3 image file with an unknown autoclear feature bit the bit should be cleared in the image file header.

qcow2: Fix error path for unknown incompatible features qcow2's report_unsupported_feature() had two bugs: A 32 bit truncation would prevent feature table entries for bits 32-63 from being used, and it could assign errp multiple times if there was more than one unknown feature, resulting in an error_set() assertion failure. Fix the truncation, make sure to set the error exactly once and add a qemu-iotests case for it.

qcow2: Add corrupt bit This adds an incompatible bit indicating corruption to qcow2. Any image with this bit set may not be written to unless for repairing (and subsequently clearing the bit if the repair has been successful).

qcow2: introduce dirty bit This patch adds an incompatible feature bit to mark images that have not been closed cleanly. When a dirty image file is opened a consistency check and repair is performed. Update qemu-iotests 031 and 036 since the extension header size changes when we add feature bit table entries.
