Commit 839a0608 tied the lifecycle of virtlogd more
closely to that of libvirtd. Unfortunately, while starting
virtlogd when libvirtd is started is definitely a good idea,
restarting virtlogd or shutting it down at any time outside
of system poweroff is not.

Revert part of that commit by removing the PartOf= lines,
meaning that only startup requests will be propagated from
libvirtd to virtlogd.

Make use of the new recently introduced alias handling for virt-admin srv-*
commands.

Change the logic in a way, so that VSH_CMD_FLAG_ALIAS behaves similarly to
how VSH_OT_ALIAS for command options, i.e. there is no need for code duplication
for the alias and the aliased command structures. Along with that change,
switch any existing VSH_CMD_FLAG_ALIAS occurrences to this new format. Also,
since this patch introduces a new command structure element, adjust the
virsh-self-test test to make sure we won't ever miss to specify the '.alias'
member for an aliased command because doing that would lead to an internal
error.

Recent changes extracted the command internals validation routine from
vshCmddefOptParse method which now just calls vshCmddefOptFill. Therefore, make
vshCmddefOptFill the new vshCmddefOptParse and drop the unnecessary name.
Signed-off-by: NErik Skultety <eskultet@redhat.com>

Originally introduced by commit 2432521e which correctly split
vshCmddefOptParse into command's options validation and options parsing.
However, command's 'internals' are not tied solely to .options, rather it
should be about the overall structure, therefore the validation should be
extracted from vshCmddefOptParse and performed only within our test suite, i.e.
in vshSelfTest.

If the initial check is true the function immediately returns so there's no
need to enclose the code following the check within an 'else' block.
Also, by removing the 'else' block, the declarations need to be moved to
beginning of the function block to conform with our guidelines.

The intention is to move vshCmddefCheckInternals out of vshCmddefOptParse to
our test suite. First step to do that is to enforce checking for an existing
help string (that also means it's non-empty) in a command because a command
without a help is not much of a use.

The recent update to gnulib

  commit 9d7a37ec
  Author: Eric Blake <eblake@redhat.com>
  Date:   Thu Sep 15 15:12:52 2016 -0500

    build: update to latest gnulib

Pulled in a change that adds -fno-common to the default compiler
flags

  commit bf8e658ffadb95d444f56d222d04c9af955af765
  Author: Jim Meyering <meyering@fb.com>
  Date:   Fri Sep 2 09:16:16 2016 -0700

    manywarnings: add -fno-common

This caused libvirt Mingw build to break with the compiler
reporting 100's of definitions of virConnectAuthPtrDefault

./.libs/libvirt_util.a(libvirt_util_la-virarch.o):virarch.c:(.bss+0x0): multiple definition of `virConnectAuthPtrDefault'

...snip...

The cause is our VIR_EXPORT_VAR macro which has some
magic on win to add dllexport/dllimport to the variable
declaration. Unfortunately the dllexport branch missed
off the 'extern' keyword, so the header file was in
fact declaring an instance of the variable in every
source file.

Previously the linker would merge all these definitions
into one, but that no longer happens due to -fno-common

Commit 85635600 switched from
hardcoded use of strcontent to hardcoded use of fixedcontent
(fixedcontent is *sometimes* a copy of strcontent with a \n
appended). This was a problem because sometimes fixedcontent is *not*
a copy of strcontent, but is instead NULL, leading to the regenerated
test case output being a 0 length file.

This patch creates a new const char *cmpcontent initialized to
strcontent, but changed to fixedcontent if/when fixedcontent is
created, then always uses cmpcontent instead of (str|fixed)content.

This reverts commit d53fa838,

Most of QEMU's PCI display device models, such as:

  libvirt video/model/@type  QEMU -device
  -------------------------  ------------
  cirrus                     cirrus-vga
  vga                        VGA
  qxl                        qxl-vga
  virtio                     virtio-vga

come with a linear framebuffer (sometimes called "VGA compatibility
framebuffer"). This linear framebuffer lives in one of the PCI device's
MMIO BARs, and allows guest code (primarily: firmware drivers, and
non-accelerated OS drivers) to display graphics with direct memory access.

Due to architectural reasons on aarch64/KVM hosts, this kind of
framebuffer doesn't / can't work in

  qemu-system-(arm|aarch64) -M virt

machines. Cache coherency issues guarantee a corrupted / unusable display.
The problem has been researched by several people, including kvm-arm
maintainers, and it's been decided that the best way (practically the only
way) to have boot time graphics for such guests is to consolidate on
QEMU's "virtio-gpu-pci" device.

>From <https://bugzilla.redhat.com/show_bug.cgi?id=1195176>, libvirt
supports

  <devices>
    <video>
      <model type='virtio'/>
    </video>
  </devices>

but libvirt unconditionally maps @type='virtio' to QEMU's "virtio-vga"
device model. (See the qemuBuildDeviceVideoStr() function and the
"qemuDeviceVideo" enum impl.)

According to the above, this is not right for the "virt" machine type; the
qemu-system-(arm|aarch64) binaries don't even recognize the "virtio-vga"
device model (justifiedly). Whereas "virtio-gpu-pci", which is a pure
virtio device without a compatibility framebuffer, is available, and works
fine.

(The ArmVirtQemu ("AAVMF") platform of edk2 -- that is, the UEFI firmware
for "virt" -- supports "virtio-gpu-pci", as of upstream commit
3ef3209d3028. See
<https://tianocore.acgmultimedia.com/show_bug.cgi?id=66>.)

Override the default mapping of "virtio", from "virtio-vga" to
"virtio-gpu-pci", if qemuDomainMachineIsVirt() evaluates to true.
