The *header_name* cannot be quoted, otherwise it is not translated to
the passed argument. Without this fix the generated configure contains
*ac_cv_header_header_name*, but there should be for example
*ac_cv_header_sals_sasl_h* for "sasl/sasl.h".

Qemu 2.8.0+ changes arguments structure for blockdev-add in the effort
to make it finally stable. Since libvirt recently added the detection of
gluster debug support relying on the old syntax we need to add the new
as well.
With current perf framework, this patch adds support and documentation
for the branch_instructions perf event.

Adjust the spacing a bit in order to generate 'cleaner' looking output.
This matches what virDomainMemoryStats does and it creates text/code boxes
in order to list each of the stats for each category.
When changing one of the src/libvirt-*.c files to alter the docs, the
adjusted files weren't being built. Added them into APIBUILD_STAMP and
then added that to the html/index.html rule which is used for the
$(apihtml_generated) generated rule.
Also, for clean we can remove the html/*.html files
With kernel 3.18 (since commit 3e32cb2e0a12b6915056ff04601cf1bb9b44f967)
the "unlimited" value for cgroup memory limits has changed once again as
its byte value is now computed from a page counter.
The new "unlimited" value reported by the cgroup fs is therefore 2**51-1
pages which is (VIR_DOMAIN_MEMORY_PARAM_UNLIMITED - 3072). This results
e.g. in virsh memtune displaying 9007199254740988 instead of unlimited
for the limits.
This patch uses the value of memory.limit_in_bytes from the cgroup
memory root which is the system's "real" unlimited value for comparison.
See also libvirt commit 231656bbeb for the
history for kernel 3.12 and before.

So far the NSS module looks up only hostnames as provided by
guests themselves. However, there are some cases where this is
not enough: e.g. when there's a fresh new guest being installed
(with some generic hostname) say from a live ISO image; or some
(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:
# virsh start $dom && ssh $dom
In order to achieve that new libvirt-guest module is introduced,
while older libvirt module maintains its current behaviour (that
is translating guest provided names into IP addresses).

The name of the exported functions for an NSS module is quite
fixed, it is derived from the module name:
_nss_$module_$function
Since we will create another NSS module with very similar
implementation we might as well generate the function names at

There are couple of places where we have a string and want to
save it to a file. Atomically. In all those places we use
virFileRewrite() but also implement the very same callback which
takes the string and write it into temp file. This makes no
sense. Unify the callbacks and move them to one place.

Problem with VIR_FREE() is that we are not linking
libvirt-utils.so to our mock libs therefore there will be an
unresolved symbol. Fortunately, nsstest that eventually links
with the nssmock links also with libvirt-utils.so and thus the
symbol is resolved after all. However, if one wants to run the
test binary under valgrind it is impossible to do so. Because of
the unresolved symbol.

Rather than have multiple bool values, create a single enum with bits
representing what fields are set. Fields are generally set in groups
of 3 (read, write, total).
Currently we build the JSON object for the "block_set_io_throttle"
command using the knowledge that a NULL for a support*Options boolean
would essentially ignore the rest of the arguments.
This may not work properly if some capability was backported, plus it just
looks rather ugly. So instead, build the "base" arguments and then if
the support*Option bool capability is set, add in the arguments on the fly.
Then append those arguments to the basic command and send to qemu.
Rather than using negative logic and setting the maxparams to a lesser
value based on which capabilities exist, alter the logic to modify the
maxparams based on a base value plus the found capabilities. Reduces the
chance that some backported feature produces an incorrect value.
These features are included:
AVX512DQ, AVX512IFMA, AVX512BW, AVX512VL, AVX512VBMI, AVX512_4VNNIW and
AVX512_4FMAPS.

Commit id '03e750f3' added support for checking the PLOOP type; however,
it used 'target.type' which no storage code ever fills in, so it will
never be set. Change to just vol->type (could use vol->target.format
as well).

Add a global check for duplicate drive addresses. This will fix the
problem of duplicate disk and hostdev drive addresses.
Example for duplicate drive addresses:
<disk>
...
<target name='sda'/>
</disk>
<disk>
...
<target name='sdb'/>
<address type='drive' controller=0 bus=0 target=0 unit=0/>
</disk>
Another example:
<hostdev mode='subsystem' type='scsi' managed='no'>
<source>
...
</source>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</hostdev>
<hostdev mode='subsystem' type='scsi' managed='no'>
<source>
...
</source>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</hostdev>
Unfortunately the fixes (1b08cc170a,
8d46386bfe) weren't enough to catch these
cases and it isn't possible to add additional checks in
virDomainDeviceDefPostParseInternal() for SCSI hostdevs or
virDomainDiskDefAssignAddress() for SCSI/IDE/FDC/SATA disks without
adding another parse flag (virDomainDefParseFlags) to disable this
validation while updating or detaching a disk or hostdev.
