This imports a simpler version of GNULIB's getpass() function
impl for Windows. Note that GNULIB's impl was buggy as it
returned a static string on UNIX, and a heap allocated string
on Windows. This new impl always heap allocates.

Files inside /dev/vfio/ can't be opened more than once, meaning
that any subsequent open calls will fail. This behavior was
introduced in kernel v3.11, commit 6d6768c61b39.
When using the VFIO driver, we open a FD to /dev/vfio/N and
pass it to QEMU. If any other call attempt for the same
/dev/vfio/N happens while QEMU is still using the file, we are
unable to open it and QEMU will report -EBUSY. This can happen
if we hotplug a PCI hostdev that belongs to the same IOMMU group
of an existing domain hostdev.
The problem and solution is similar to what we already dealt
with for TPM in commit 4e95cdcbb3. This patch changes both
DAC and SELinux drivers to disable 'remember' for VFIO hostdevs
in virSecurityDACSetHostdevLabelHelper() and
virSecurityDACSetHostdevLabel(), and 'recall'
in virSecurityDACRestoreHostdevLabel() and
virSecuritySELinuxRestoreHostdevSubsysLabel().

There is a case in which we do not want 'remember' to be
set to true in SetOwnership() calls inside the
HostdevLabelHelper() functions of both DAC and SELinux drivers.
Next patch will explain and handle that scenario.
For now, let's make virSecurityDACSetOwnership() and
virSecuritySELinuxSetHostdevLabelHelper() accept a 'remember'
flag, which will be used to set the 'remember' parameter
of their respective SetOwnership() calls. No functional
change is made.

Currently when disk is removed from iotune group (by setting

tunables to zero may require different set of zero settings in API

For example if disk is not in the group and we want to move it
there then it makes sense to specify only the group name in API call.
Currently the destination group iotune settings will be overwritten
with the disk settings which I would say is not what one would expect.
Thus let's get defaults from the group we are moving to.
And if we are moving the brand new group then is makes sense to
copy the current disk iotune settings to the group.

Currently, if only iotune group name is given for some disk and
no any params then later start of domain will fail. I guess it
will be convenient to allow such configuration if there is
another disk in the same iotune group with iotune params set. The
meaning is that the first disk have same iotunes and the latter.
Thus one can easily add a disk to iotune group - just add group
name parameter and no need to copy all the params.
Also let's expand iotunes params in the described case so we don't
need to refer to another disk to know iotunes and this will make
logic in many places simple.
