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.

The imagelabel SELinux label was only generated when relabeling was
enabled. This prohibited labeling of files created by libvirt that need
to be labeled even if relabeling is turned off.
The only codepath this change has direct impact on is labeling of FDs
passed to qemu which is always safe in current state.
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.
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.

<spinlocks state='off'/>

results in:
error: XML error: missing HyperV spinlock retry count
Don't require retries when state is off and use virXPathUInt
instead of virXPathString to simplify parsing.

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
libvirt-xml domain config).

While iterating with virDomainObjListForEach it is safe to remove

can't use standard virDomainObjListRemove. So introduce
virDomainObjListRemoveLocked for this purpose.

The latest mingw headers on Fedora 19 fail to build with gnulib
without an update.
Meanwhile, now that upstream gnulib has better handling of -W
probing for clang, we can drop some of our own solutions in
favor of upstream; thus this reverts commit c1634100, "Correctly
detect warning flags with clang".

The 'check-aclrules' test case validates that there are ACL

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.

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.
Add monitor callback API domainGuestPanic, that implements
'destroy', 'restart' and 'preserve' events of the 'on_crash'

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:
GEN libvirt.syms
cat: libvirt_access.syms: No such file or directory
cat: libvirt_access_qemu.syms: No such file or directory
cat: libvirt_access_lxc.syms: No such file or directory
make: *** [libvirt.syms] Error 1
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).
* src/Makefile.am (USED_SYM_FILES): Don't include generated files.
(GENERATED_SYM_FILES): Access syms files are generated.

On Fedora 18, when cross-compiling to mingw with the mingw*-dbus
packages installed, compilation fails with:

I have reported this as a bug against two packages:
- mingw-headers, for polluting the namespace
https://bugzilla.redhat.com/show_bug.cgi?id=980270
- dbus, for not dealing with the pollution
https://bugzilla.redhat.com/show_bug.cgi?id=980278
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.
