If the ipv6 kernel module is not loaded, then we get this when starting
a virtual network:
libvir: Network Config error :
cannot enable /proc/sys/net/ipv6/conf/virbr0/disable_ipv6:
No such file or directory
If disable_ipv6 is not present, we should just merrily continue on our
way.
* src/network_driver.c: make networkDisableIPV6() not fail if the kernel
has no ipv6 support
Allow qemu user to open kernel/initrds in this dir, but still prevent
others from listing it.
* libvirt.spec.in: set /var/lib/libvirt/boot perms to 0711
If we're running qemu unprivileged, we need to chown any supplied kernel
or initrd before spawning it.
* src/qemu_driver.c: rename qemuDomainSetDiskOwnership() to
qemuDomainSetFileOwnership(), pass it a path string instead of a disk
definition and use it for chowning the kernel/initrd in
qemuDomainSetAllDeviceOwnership()
While trying to remove uses of unsafe strncpy in the tree, I came
across a couple of usages in the ESX driver. To my eyes, the snprintf
replacements do the same thing in less code, and are also safer.

* src/logging.c src/logging.h src/libvirt_private.syms:
define new functions virLogSetFromEnv and virLogParseDefaultPriority
* qemud/qemud.c src/libvirt.c tests/eventtest.c: cleanup to use the
unified functions
* qemud/qemud.c src/logging.[ch]: Similar as for general libvirt, don't
convert high priority levels to debug level. Ignore LIBVIRT_LOG_FILTERS
and LIBVIRT_LOG_OUTPUTS when they're set to the empty string, otherwise
they can override a valid setting from the config file. Send all
settings through the parser functions for validation, so that the
existence of a bad setting doesn't nullify a good setting that should
have applied -- particularly the default output. Keep the order of
precedence consistent for all variables between the environment and
the config file. Warn when an invalid log level, filter, or output
is ignored.
* src/libvirt_private.syms: export internally a few convenience functions
* src/libvirt.c src/logging.c: Don't convert high priority levels to the
debug level. Don't parse LIBVIRT_LOG_FILTERS and LIBVIRT_LOG_OUTPUTS
when they're set to the empty string. Warn when the user specifies an
invalid value (empty string remains a noop).
* po/POTFILES.in: src/logging.c now include translatable strings
* src/xm_internal.c: in case of multiple connections to the xen driver
and some clients were not using domain events, the whole /etc/xen
monitoring would break leading to disapearing domains.
* src/esx/esx_driver.c src/esx/esx_vi.[ch] src/esx/esx_vmx.[ch]:
adds version checking for GSX 2.0, allows to pass a specific port
for the connection and also add a new specific gsx scheme for
easier connections to GSX hosts
Fix up qemudDomainMigratePrepare2 to use virGetHostname instead of
gethostname. Besides the fact that virGetHostname is far more clever,
there was a latent bug in the handling that could cause a buffer overflow
on a very long hostname.

* autobuild.sh, mingw32-libvirt.spec.in: Enable esx on mingw32
* src/esx/esx_driver.c: Define AI_ADDRCONFIG if not set
* src/esx/esx_util.c, src/esx/esx_vi_types.c: Always use
%lld & friends, since gnulib guarentees we have these
and not the target's own variants
If the bridge device is configured to have IPv6 address and
accept router advertisments, then a malicious guest can send
out bogus advertisments and hijack/DOS host IPv6 connectivity
* src/network_driver.c: Set accept_ra=0, disable_ipv6=1, autoconf=0
for IPv6 sysctl on virual network bridge devices
PCIe DevCap register is actually 32 bits, not 16 bits. Since FLR is
bit 28, we clearly are failing to detect FLR support.
Known to fix device reset with some SR-IOV devices.
* src/pci.c: fix pciDetectFunctionLevelReset()
* src/util.c: Don't drop capabilities until after the PID file has
been written. Kill off child if writing the PID file fails
* src/qemu_driver.c: Remove bogus trailing '/' in state dir
