qcow2: Fix error handling in qcow2_grow_l1_table

Return the appropriate error value instead of always using EIO. Don't free the
L1 table on errors, we still need it.

Clean-up a little bit the RW related bits of BDRV_O_FLAGS. BDRV_O_RDONLY gone (and so is BDRV_O_ACCESS). Default value for bdrv_flags (0/zero) is READ-ONLY. Need to explicitly request READ-WRITE.

Instead of using the field 'readonly' of the BlockDriverState struct for passing the request,...

raw-posix: Detect CDROM via ioctl on linux

Current CDROM detection is hardcoded based on source file name.
Make this smarter on linux by attempting a CDROM specific ioctl.

This makes '-cdrom /dev/sr0' succeed with no media present.

v2:
Give ioctl check higher priority than filename check....

qcow/qcow2: implement bdrv_aio_flush

Now that we do not have to flush the backing device anymore implementing
the bdrv_aio_flush method for image formats is trivial.

dmg: fix ->open failure

Currently the dmg image format driver simply opens the images as raw
if any kind of failure happens. This is contrarty to the behaviour
of all other image formats which just return an error and let the
block core deal with it.
