The kernel didn't support the unprivileged SGIO for SCSI generic
device finally, and since it's unknow whether the way to support
unprivileged SGIO for SCSI generic device will be similar as for
SCSI block device or not, even it's simliar (I.e. via sysfs, for
SCSI block device, it's /sys/dev/block/8\:0/queue/unpriv_sgio,
for example), the file name might be different, So it's better not
guess what it should be like currently.

This patch removes the related code (mainly about the "shareable"
checking on the "sgio" setting, it's not supported at all, why
we leave checking code there? :-), and error out if "sgio" is
specified in the domain config.

This is a request for adding a VMmanager application as requested and
described by Ksenya Phil.

As soon as any guest mounts xenfs to /proc/xen, there is a capabilities
file in that directory. However it returns nothing when reading from it.
Change the test to actually check the contents of the file.

While running vircryptotest, it was found that valgrind pointed out the
following error:

...and many more.  Two observations: hashstrlen was already set
to include the trailing NUL byte (so writing to hashstrlen as
the array offset was indeed writing one byte beyond bounds), and
VIR_ALLOC_N already guarantees zero-initialization (so we already
have a trailing NUL without needing to explicitly write one).

Commit b4bbaeef changed char* to const char*, but omitted
the non-Linux version.

Add pci passthrough to libxl driver, support attach-device, detach-device and
start a vm with pci hostdev specified.

Add VIR_DOMAIN_HOSTDEV_PCI_BACKEND_XEN. For legacy xen, it will use "pciback" as
stub driver.

Add unit test for hostdev common library. Current tests are based on virpcimock.

Mark many parameters as NONNULL and check for empty list of
hostdevs.

Changes parameter from vm def to specific hostdevs info and name info, so that
it could be used more widely, e.g, could be used without full vm def info.

Change any variable names with Usb, Pci or Scsi to use
USB, PCI and SCSI since they are abbreviations.

Some virHostdevXXXX methods included the string Hostdev again
as a suffix. Change the latter to Device instead.
