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...

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

blockdev: enable discard by default

Because discard is now a host parameter, we can always fake it as enabled
in the guest. This is an extension of the current choice to ignore
"not supported" errors from the host when discard_granularity is set
to nonzero....
