Currently, the openvzDomainSetNetwork function constructs an
array of strings representing a command line for VZCTL binary.
This is a overkill since our virCommand APIs can cover all the
functionality. Moreover, the function is not following our
structure where return value is set to -1 initially, and after
all operations succeeded then it is set to zero.

Since 0d70656a, it starts to access the sysfs files to build
the qemu command line (by virSCSIDeviceGetSgName, which is to find
out the scsi generic device name by adpater:bus:target:unit), there
is no way to work around, qemu wants to see the scsi generic device
like "/dev/sg6" anyway.

And there might be other places which need to access sysfs files
when building qemu command line in future.

Instead of increasing the arguments of qemuBuildCommandLine, this
introduces a new callback for qemuBuildCommandLine, and thus tests
can register their own callbacks for sysfs test input files accessing.

* src/qemu/qemu_command.h: (New callback struct
                            qemuBuildCommandLineCallbacks;
                            extern buildCommandLineCallbacks)
* src/qemu/qemu_command.c: (wire up the callback struct)
* src/qemu/qemu_driver.c: (Use the new syntax of qemuBuildCommandLine)
* src/qemu/qemu_hotplug.c: Likewise
* src/qemu/qemu_process.c: Likewise
* tests/testutilsqemu.[ch]: (Helper testSCSIDeviceGetSgName;
                             callback struct testCallbacks;)
* tests/qemuxml2argvtest.c: (Use testCallbacks)
* src/tests/qemuxmlnstest.c: (Like above)

Changes:
  * Remove useless comments
  * Remove useless blank lines
  * If the struct member is a enum type, comment it like
    /* enum fooBar */
  * Break the long lines
  * Prefer the common function style for the inline function

Uses the 4 spaces for indention.

Changes:
  * Remove the useless space in "for" statement (e.g.
    for (i = 0 ; i < something ; i++)

  * Change the function's style to:
    void
    foo(bar)
    {
        printf("foo is not bar\n");
    }

  * Don't lose "{}" for "if...else" branches if one of the branch
    has more than one line block. Example of the old ones:
    if (a) {
        printf("a is not funny");
    } else
        printf("a is funny");

  * Remove the 1 space before "goto" label.

  * Remove the useless blank line(s)

  * Add blank line if it can make the code more clear to eyes.

As the name parameter can be NULL the error message can only contain it
conditionally.

The mkdtemp function is missing on mingw platforms. It is
used in various Linux specific places in libvirt, but
recently became used in fdstreamtest.c which is cross
platform. Thus the GNULIB mkdtemp module should be used
to provide mkdtemp.

If PKG_CONFIG_LIBDIR is not set when doing mingw32/64 builds,
then pkg-config may silently fallback to native versions of
libraries, with predictably bad results. Setting PKG_CONFIG_LIBDIR
forces it to only consider the mingw32/64 libraries.

 #kill -STOP `pidof qemu-kvm`
 #virsh destroy $guest --graceful
 error: Failed to destroy domain testVM
 error: An error occurred, but the cause is unknown

With --graceful, SIGTERM always is emitted to kill driver
process, but it won't success till burning out waiting time
in case of process being stopped.
But domain destroy without --graceful can work, SIGKILL will
be emitted to the stopped process after 10 secs which always
kills a process even one that is currently stopped.
So report an error after burning out waiting time in this case.

Just like previous patches, this changes qemuCheckSharedDisk
into qemuCheckSharedDevice, which takes a virDomainDeviceDefPtr
argument instead.

Running make check in a VPATH configured build directory fails
in fchosttest as the test data files are searched for relative to
the current working directory.

Change bbe97ae9 caused the
QEMU driver to ignore ENOENT errors from cgroups, in order
to cope with missing /proc/cgroups. This is not good though
because many other things can cause ENOENT and should not
be ignored. The callers expect to see ENXIO when cgroups
are not present, so adjust the code to report that errno
when /proc/cgroups is missing

This reverts commit 940c6f10.

libxl expects the event handler to free the event passed to it.  From
libxl_event.h:

   event becomes owned by the application and must be freed, either
   by event_occurs or later

Xen 4.3 fixes a mistake in the libxl event handler signature where the
event owned by the application was defined as const.  Detect this and
define the libvirt libxl event handler signature appropriately.

We don't parse it anyway.

Make target path mandatory for pool types that require target,
since we refuse to parse a target without a path.

QEMU might support more values for "-drive discard", so using Bi-state
values (on/off) for it doesn't make sense.

"on" maps to "unmap", "off" maps to "ignore":

<...>
@var{discard} is one of "ignore" (or "off") or "unmap" (or "on") and
controls whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
requests are ignored or passed to the filesystem.  Some machine types
may not support discard requests.
</...>

The following XML configuration can be used to request all domain's
memory pages to be kept locked in host's memory (i.e., domain's memory
pages will not be swapped out):

      <memoryBacking>
        <locked/>
      </memoryBacking>

was missing variable left out and due to passed NULL to underlying

Just like what previous patches do, it refactors qemuSetUnprivSGIO
to take the virDomainDeviceDefPtr as argument instead.

unpriv_sgio setting is tight with the shared device helpers, let's
put them together in qemu_conf.c

"sgio" is only valid for scsi host device.

SCSI host device will also support "sgio", and perhaps we could
use "sgio" in other places too in future, renaming the enum to
reuse.

This adds the shared device entry when starting domain (more
exactly, when preparing host devices), and remove the entry
when destroying domain (when reattaching host devices).

This changes the helpers qemu{Add,Remove}SharedDisk into
qemu{Add,Remove}SharedDevice, as most of the code in the helpers
can be reused for scsi host device.

To track the shared scsi host device, first it finds out the
device path (e.g. /dev/s[dr]*) which is mapped to the sg device,
and use device ID of the found device path (/dev/s[dr]*) as the
hash key. This is because of the device ID is not unique between
between /dev/s[dr]* and /dev/sg*, e.g.

% sg_map
/dev/sg0  /dev/sda
/dev/sg1  /dev/sr0

% ls -l /dev/sda
brw-rw----. 1 root disk 8, 0 May  2 19:26 /dev/sda

%ls -l /dev/sg0
crw-rw----. 1 root disk 21, 0 May  2 19:26 /dev/sg0
