Apologies - I tripped over the if (dev->started && r < 0) check.
Never-mind my point with race conditions and failing migrations.
Rather than modifying vhost_dev_set_log(), it may be clearer to put a
check after vhost_

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 al
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.

Hi!
Here is the updated series of my patches, incorporating all the feedback I
received.
This implements the API interface that we agreed upon except that I merged the
LUKSKeyslotActive/LUKSKeyslotInactive union into a struct because otherwise
I need nested unions which are not supported currentl
'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.
