Actually, I'm turning this function into a macro as filename,
function name and line number needs to be passed. The new
function virAsprintfInternal is introduced with the extended set
of arguments.
Initially proposed as [1], but then changed to comment fix only. VMDK
can have internal version set to 2 when there are few features added
which do not affect us. Thanks to Jan's commit a1ee8e18 this can be
easily fixed by adding it to list of supported versions.

build: honor autogen.sh --no-git
Based on a report by Chandrashekar Shastri, at
https://bugzilla.redhat.com/show_bug.cgi?id=979360
On systems where git cannot access the outside world, a developer
can instead arrange to get a copy of gnulib at the right commit
via side channels (such as NFS share drives), set GNULIB_SRCDIR,
then use ./autogen.sh --no-git. In this setup, we will now
avoid direct use of git. Of course, this means no automatic
gnulib updates when libvirt.git updates its submodule, but it
is expected that any developer in such a situation is already
prepared to deal with the fallout.
* .gnulib: Update to latest, for bootstrap.
* bootstrap: Synchronize from gnulib.
* autogen.sh (no_git): Avoid git when requested.
* cfg.mk (_update_required): Skip automatic rerun of bootstrap if
we can't use git.
* docs/compiling.html.in: Document this setup.
* docs/hacking.html.in: Mention this.

maint: tweak use of <a> in HACKING
The previous handling of <a> tags led to some less-than-ideal
layout in HACKING (most noticeable on a mid-sentence reference
to the valgrind home page).
This helper function is used to create parent directory for
the hostdev which will be added to the container. If the
parent directory of this hostdev doesn't exist, the mknod of
the hostdev will fail. eg with /dev/net/tun
Many applications use /dev/tty to read from stdin.
e.g. zypper on openSUSE.
Let's create this device node to unbreak those applications.
As /dev/tty is a synonym for the current controlling terminal
it cannot harm the host or any other containers.

selinux: Always generate imagelabel

passed to qemu which is always safe in current state.

Resolve Coverity complaints in tests/securityselinuxlabeltest.c
Two complaints of RESOURCE_FREE due to going to cleanup prior to a
VIR_FREE(line). Two complaints of FORWARD_NULL due to 'tmp' being
accessed after a strchr() without first checking if the return was NULL.
While looking at the code it seems that 'line' need only be allocated
once as the while loop will keep reading into line until eof causing
an unreported leak since line was never VIR_FREE()'d at the bottom of
the loop.
Don't spam logs with "port 0 must be in range" errors
Whenever virPortAllocatorRelease is called with port == 0, it complains
that the port is not in an allowed range, which is expectable as the
port was never allocated. Let's make virPortAllocatorRelease ignore 0
ports in a similar way free() ignores NULL pointers.
If a domain is paused before migration starts, we need to tell that to
the destination libvirtd to prevent it from resuming the domain at the
end of migration. This regression was introduced by commit 5379bb0.

Fix build with clang
Partially revert cdd703f's revert of c163410, as linking with clang
with --param=ssp-buffer-size=4 still fails with:
"argument unused during compilation".
Use virDomainObjListRemoveLocked instead of virDomainObjListRemove, as
driver->domains is already taken by virDomainObjListForEach.
Above deadlock can be triggered when libvirtd is started after some
domain have been started by hand (in which case driver will not find

Extend the ACL test case to validate filter rule checks

Ensure that all APIs which list interface objects filter
them against the access control system.
This makes the APIs for listing names and counting devices
slightly less efficient, since we can't use the direct
netcf APIs for these tasks. Instead we have to ask netcf
for the full list of objects & iterate over the list
filtering them out.

qemu: Allow seamless migration for domains with multiple graphics
Since commit 23e8b5d8, the code is refactored in a way that supports
domains with multiple graphics elements and commit 37b415200 allows
starting such domains. However none of those commits take migration
into account. Even though qemu doesn't support relocation for
anything else than SPICE and for no more than one graphics, there is no
reason to hardcode one graphics into this part of the code as well.
When removing a TAP device, the associated bandwidth settings are
removed. Currently, the /sbin/tc is used for that. It is spawned
several times. Moreover, we use the same @cmd variable to
construct the command and its arguments. That means we need to
virCommandFree(cmd); prior to each virCommandNew(TC); which
wasn't done.

build: don't ship access syms files in tarball
On a mingw VPATH build (such as done by ./autobuild.sh), the tarball
created by 'make dist' was including generated files. The VPATH
rules were then seeing that the tarball files were up-to-date, and
not regenerating files locally, leading to this failure:

We already have a category for generated sym files, which are
intentionally not part of the tarball; stick the access sym
files in that category. The rearrange the declarations a bit
to make it harder to repeat the problem, dropping things that
are now redundant (for example, BUILT_FILES already includes
GENERATED_SYM_FILES, so it does not also need to call out
ACCESS_DRIVER_SYM_FILES).

- dbus, for not dealing with the pollution

At least dbus has agreed that a future version of dbus headers will
do s/interface/iface/, regardless of what happens in mingw. But it
is also easy to workaround in libvirt in the meantime, without having
to wait for either mingw or dbus to upgrade.
* src/util/virdbus.h (includes): Undo mingw's pollution so that
dbus doesn't fail.
