Kevin Wolf def93791f2 ide: Split error status from status register
When adding the werror=stop mode, some flags were added to s->status
which are used to determine what kind of operation should be restarted
when the VM is continued.

Unfortunately, it turns out that s->status is in fact a device register
and as such is visible to the guest (some of the abused bits are even
writable for the guest).

For migration we keep on using the old VMState field (renamed to
migration_compat_status) if the status register doesn't use any of the
previously abused bits. If it does, we use a subsection with a clean copy of
the status register.

The error status is always sent in a subsection if there is any error. It can't
use the old field because errors happen even without PCI.

Alexander Graf 40a6238a20 ide: Split out BMDMA code from ATA core
The ATA core is currently heavily intertwined with BMDMA code. Let's loosen
that a bit, so we can happily replace the DMA backend with different
implementations.
