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.

block: drop bs_snapshots global variable
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.

Commit d08151bf (conversion of tcx to the memory API) broke the 24-bit mode of
the tcx display adapter by accidentally passing in the final address of the
dirty region to memory_region_reset_dirty() instead of its size.

Remove some code duplication by adding a
function to look up the fw cfg file.
This way, we don't need to duplicate same strings everywhere.
Use by both fw cfg and pvpanic device.

firmware_abi.h with structs for OpenBIOS landed in hw/sparc/ by mistake
- move it to hw/nvram/ alongside fw_cfg.h. In addition to sparc it's
included from ppc mac_nvram.c and will need to include it from prep.c in
the future.

configure: try pkg-config ncurses first
When probing for ncurses, try pkg-config first rather than after
explicit -lncurses and -lcurses. This fixes static linking in the case
that ncurses has additional dependencies, such as -ltinfo (as on FreeBSD).

configure: remove confusing file manipulation
The configure script had some code to manipulate config-host.ld~ (i.e.,
a common backup filename), comparing it with the newly-generated file.
I believe the sense of the comparison was backwards.
Since it seemed to serve little purpose anyway, remove it to avoid any
confusion.

target-i386: Fix aflag logic for CODE64 and the 0x67 prefix
The code reorganization in commit 4a6fd938 broke handling of PREFIX_ADR.
While fixing this, tidy and comment the code so that it's more obvious
what's going on in setting both aflag and dflag.
The TARGET_X86_64 ifdef can be eliminated because CODE64 expands to the
constant zero when TARGET_X86_64 is undefined.

With the ccw ipl code sometimes an error message like
"virtio: trying to map MMIO memory" or
"Guest moved used index from %u to %u" appeared. Turns out
that the ccw bios did not zero out the vring, which might
cause stale values in avail->idx and friends, especially
on reboot.
Lets zero out the relevant fields. To activate the patch we
need to rebuild s390-ccw.img as well.
