  raw-posix: Deprecate host floppy passthrough

Raise your hand if you have a physical floppy drive in a computer
you've powered on in 2015.  Okay, I see we got a few weirdos in the
audience.  That's okay, weirdos are welcome here.

Kidding aside, media change detection doesn't fully work, isn't going
to be fixed, and floppy passthrough just isn't earning its keep
anymore.

Deprecate block driver host_floppy now, so we can drop it after a
grace period.

  raw-posix: Deprecate aio=threads fallback without O_DIRECT

Currently, if the user requests aio=native, but forgets to choose a
cache mode that sets O_DIRECT, that request is silently ignored and raw
falls back to aio=threads.

Deprecate that behaviour so we can make it an error in future qemu
versions.

  block: Fix blockdev-backup not to use funky error class

Error classes are a leftover from the days of "rich" error objects.
New code should always use ERROR_CLASS_GENERIC_ERROR.  Commit
b7b9d39..7c6a4ab added uses of ERROR_CLASS_DEVICE_NOT_FOUND.  Replace
them.
