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.
Avoid this by setting BUSY_STAT, so that the guest is made aware we are
in the middle of an operation and no ATA commands are attempted to be
processed concurrently.

Paolo Bonzini <pbonzini@redhat.com> suggested the following test case:
1. Launch a guest and wait at the GRUB boot menu:
qemu-system-x86_64 -enable-kvm -m 1024 \
-drive if=none,cache=none,file=test.img,id=foo,werror=stop,rerror=stop
-device virtio-blk-pci,drive=foo,id=virtio0,addr=4
2. Hot unplug the device:
(qemu) drive_del foo
3. Select the first boot menu entry
Without this patch the guest pauses due to ENOMEDIUM. The guest is
stuck in a continuous pause loop since the I/O request is retried and
fails immediately again when the guest is resumed.
With this patch the error is reported to the guest.
Note that this scenario actually happens sometimes during libvirt disk
hot unplug, where device_del is followed by drive_del. I/O may still be
submitted to the drive after drive_del if the guest does not process the
PCI hot unplug notification.

4 collect_snapshots() and collect_image_info() are renamed, unused parameter

The bs_snapshots global variable points to the BlockDriverState which
will be used to save vmstate. This is really a savevm.c concept but was
moved into block.c:bdrv_snapshots() when it became clear that hotplug
could result in a dangling pointer.
While auditing the block layer's global state I came upon bs_snapshots
and realized that a variable is not necessary here. Simply find the
first BlockDriverState capable of internal snapshots each time this is
needed.
The behavior of bdrv_snapshots() is preserved across hotplug because new
drives are always appended to the bdrv_states list. This means that
calling the new find_vmstate_bs() function is idempotent - it returns
the same BlockDriverState unless it was hot-unplugged.

We may want to include a driver in the whitelist for read only tasks
such as diagnosing or exporting guest data (with libguestfs as a good
example). This patch introduces a readonly whitelist option, and for
backward compatibility, the old configure option --block-drv-whitelist
is now an alias to rw whitelist.
Drivers in readonly list is only permitted to open file readonly, and
returns -ENOTSUP for RW opening.
E.g. To include vmdk readonly, and others read+write:
./configure --target-list=x86_64-softmmu \
--block-drv-rw-whitelist=qcow2,raw,file,qed \
