isa: Use realizefn for ISADevice

Drop ISADeviceClass::init and the resulting no-op initfn and let
children implement their own realizefn. Adapt error handling.
Split off an instance_init where sensible.

ide: Set BSY bit during FLUSH

The implementation of the ATA FLUSH command invokes a flush at the block
layer, which may on raw files on POSIX entail a synchronous fdatasync().
This may in some cases take so long that the SLES 11 SP1 guest driver
reports I/O errors and filesystems get corrupted or remounted read-only....

ide/macio: fix wrong opaque with TRIM support

Commit 215e47b9 enabled TRIM by default, which revealed a bug in TRIM
support for the IDE macio emulation driver, introduced in d353fb72.

The call to dma_bdrv_io() is using a wrong opaque of type IDEState
instead of DBDMA_io. This patch fixes that....

ahci: Don't allow creating slave drives

An IDE bus provided by AHCI can only take a single IDE drive. If you add
a drive as slave, qemu used to accept the command line but the device
wouldn't be actually usable. Catch the situation instead and error out....

ide: Reset BMIDEA bit when the bus master is stopped

The device is supposed to reset the Bus Master IDE Active bit in the
status register when 0 is written to the Start/Stop Bus Master bit in
the command register.

In the common cases this happens automatically because bdrv_drain_all()...

include: avoid useless includes of exec/ headers

Headers in include/exec/ are for the deepest innards of QEMU,
they should almost never be included directly.

ide: refuse WIN_READ_NATIVE_MAX on empty device

What is the highest addressable sector on an empty CD-ROM? Nothing is
addressable so produce an error.

This patch prevents a divide-by-zero in ide_set_sector() since
s->sectors and s->heads would be 0. Not to mention that a sector=-1...
