  linux-user: fix emulation of getdents

In case when TARGET_ABI_BITS == 32 && HOST_LONG_BITS == 64, the last
byte of the target dirent structure (aka d_type byte) was never copied
from the host dirent structure, thus breaking everything that relies
on valid d_type value, e.g. glob(3).

  linux-user: Clarify "Unable to reserve guest address space" error

Now that we default to reserving nearly 4GB of RAM for the guest
address space when running a 32 bit linux-user guest on 64 bit
hosts, users are much more likely to run into it. Reword the
message to be more informative about what failed and provide
suggestions for how to fix things.

It also did not touch scsi-generic, while it should have.

  Log Message:
  -----------
  iscsi: Set number of blocks to 0 for blank CDROM devices

The number of blocks of the device is used to compute the device size
in bdrv_getlength()/iscsi_getlength().
For MMC devices, the ReturnedLogicalBlockAddress in the READCAPACITY10
has a special meaning when it is 0.
In this case it does not mean that LBA 0 is the last accessible LBA,
and thus the device has 1 readable block, but instead it means that the
disc is blank and there are no readable blocks.

This change ensures that when the iSCSI LUN is loaded with a blank
DVD-R disk or similar that bdrv_getlength() will return the correct
size of the device as 0 bytes.

  target-i386: disable pv eoi to fix migration across QEMU versions

We have a problem with how we handle migration with KVM paravirt features.
We unconditionally enable paravirt features regardless of whether we know how
to migrate them.

We also don't tie paravirt features to specific machine types so an old QEMU on
a new kernel would expose features that never existed.

The 1.2 cycle is over and as things stand, migration is broken.  Michael has
another series that adds support for migrating PV EOI and attempts to make it
work correctly for different machine types.

After speaking with Michael on IRC, we agreed to take this patch plus 1 & 4
from his series.  This makes sure QEMU can migrate PV EOI if it's enabled, but
does not enable it by default.

This also means that we won't unconditionally enable new features for guests
future proofing us from this happening again in the future.

  msix: make [un]use vectors on reset/load optional

The facility to use/unuse vectors dynamically is helpful
for virtio but little else: everyone just seems to use
vectors in their init function.

Avoid clearing msix vector use info on reset and load.
For virtio, clear it explicitly.
This should fix regressions reported with ivshmem - though
I didn't test this, I verified that virtio keeps
working like it did.
