'force' option will be used for some unsafe amend operations.
This includes things like erasing last keyslot in luks based formats
(which destroys the data, unless the master key is backed up
by external means), but that _might_ be desired result.

Some options are only useful for creation
(or hard to be amended, like cluster size for qcow2), while some other
options are only useful for amend, like upcoming keyslot management
options for luks
Since currently only qcow2 supports amend, move all its options
to a common macro and then include it in each action option list.
In future it might be useful to remove some options which are
not supported anyway from amend list, which currently
cause an error message if amended.

Last week (when I was about to prepare a pull request), I noticed that
this patch breaks the iotests 134 and 158 for qcow (v1). That’s because
as of this patch, qcow2 has a different order of creation options than qcow.
We could easily fix this by moving HEAD^:134.out and HEAD^:158.out to
134.out.qcow and 158.out.qcow, respectively, and HEAD:134.out and
HEAD:158.out to 134.out.qcow2 and 158.out.qcow2, respectively.
But the underlying problem is a greater one: The order of creation
options isn’t fixed between different formats, so I think
_filter_img_create should sort it so it’s the same for all.
To do so, I just sent the “iotests: Make _filter_img_create more active”
series. We could put that underneath your series and then the problem
would be fixed, too (and we could drop some of the hunks from this
patch, because the option order wouldn’t change for any test that uses
_filter_img_create).

rename the write_func to create_write_func, and init_func to create_init_func.
This is preparation for other write_func that will be used to update the encryption keys.
No functional changes

This implements the encryption key management using the generic code in
qcrypto layer and exposes it to the user via qemu-img
This code adds another 'write_func' because the initialization
write_func works directly on the underlying file, and amend
works on instance of luks device.
This commit also adds a 'hack/workaround' I and Kevin Wolf (thanks)
made to make the driver both support write sharing (to avoid breaking the users),
and be safe against concurrent metadata update (the keyslots)
Eventually the write sharing for luks driver will be deprecated
and removed together with this hack.
The hack is that we ask (as a format driver) for BLK_PERM_CONSISTENT_READ
and then when we want to update the keys, we unshare that permission.
So if someone else has the image open, even readonly, encryption
key update will fail gracefully.
Also thanks to Daniel Berrange for the idea of
unsharing read, rather that write permission which allows
to avoid cases when the other user had opened the image read-only.

Well, it isn’t wrong to have this be a const, nor is it against any
coding guidelines. While I do believe this was an accident, I also
think that in fact, maybe being strict about const-ness is what we
should’ve done everywhere from the start.
So this is not a complaint, quite the contrary.
(I felt it was interesting enough to warrant this mail. *shrug*)

Now that we have all the infrastructure in place,
wire it in the qcow2 driver and expose this to the user.

blockdev-amend will be used similiar to blockdev-create
to allow on the fly changes of the structure of the format based block devices.
Current plan is to first support encryption keyslot management for luks
based formats (raw and embedded in qcow2)

Apparently I didn't add #include of qapi-types-block-core.h in block_int.h (I'll fix this in a patch soon),
but it looks like throttle-groups.h includes "qemu/throttle.h" which includes "qapi/qapi-types-block-core.h",
so it should be included explicitly here.
Could you share your configure.sh options?
