e399641561 tests: Remove pointless _CFLAGS variables
If _CFLAGS for a binary is not specified it uses AM_CFLAGS.  So doing

  $binary_CFLAGS = $(AM_CFLAGS)

or

  $binary_CFLAGS = $(AM_CFLAGS) $(something_that_is_already_in_AM_CFLAGS)

is pointless.  So remove it for cleaner Makefile.am

74a13be4a4 build: Use XDR_CFLAGS in more places
Since update to glibc-2.26 removed the /usr/include/rpc/rpc.h we used until now,
it showed us a problem with not using XDR_CFLAGS properly.  On linux that
variable has usually -I/usr/include/tirpc because we already probe for it
properly, we just don't use it everywhere we need.  It is needed by wireshark
dissector as well as testutilsqemu.c (through includes) so the build fails with:

wireshark/src/packet-libvirt.c:33:10: fatal error: rpc/xdr.h: No such file or directory
 #include <rpc/xdr.h>
          ^~~~~~~~~~~

and

In file included from ../src/logging/log_manager.h:29:0,
                 from ../src/qemu/qemu_domain.h:40,
                 from testutilsqemu.c:11:
../src/logging/log_protocol.h:9:10: fatal error: rpc/rpc.h: No such file or directory
 #include <rpc/rpc.h>
          ^~~~~~~~~~~

Since lot of tests use testutilsqemu.c it is easier to add XDR_CFLAGS to
AM_CFLAGS than adding it to all $binary_CFLAGS.  It's just for tests and we
already have bunch of CFLAGS there anyway.

9061b3090e docs: add a page describing support guarantees for libvirt features
While we have collective knowledge about the support status of various
parts of libvirt, this has never been formally documented, leaving our
users to guess.

Note, this document makes one change to our previous policy. It explicitly
declares the RPC protocol of libvirtd as being a supported interface. THis
accepts the reality that we can a) never change it without breaking compat
with old libvirt.so, b) there are both rust + go impls that are written
against the RPC protocol already.

2dd70901db storage: Resolve storage driver crash
Resolve a storage driver crash as a result of a long running
storageVolCreateXML when the virStorageVolPoolRefreshThread is
run as a result of when a storageVolUpload completed and ran the
virStoragePoolObjClearVols without checking if the creation
code was currently processing a buildVol after incrementing
the driver->asyncjob count.

The refreshThread will now check the pool asyncjob count before
attempting to pursue the pool refresh. Adjust the documentation
to describe the condition.

Crash from valgrind is as follows (with a bit of editing):

5f244e3161 vircapstest: Avoid (im)possible strcmp call with NULL argument
Some compilers may get confused and decide we are calling strcmp with
NULL argument from test_virCapsDomainDataLookupLXC. Although this does
not really happen since the call is guarded with
(data->machinetype != expect_machinetype), using STRNEQ_NULLABLE is
easier to understand, less fragile, and doing so makes sure strcmp is

          <sibling id='3' value='10'/>
        </distances>
      </cell>
    </numa>
  </cpu>

A <cell> defines a NUMA node. <distances> describes the NUMA distance
from the <cell> to the other NUMA nodes (the <sibling>s).  For example,
in above XML description, the distance between NUMA node0 <cell id='0'
...> and NUMA node2 <sibling id='2' ...> is 31.

Valid distance values are '10 <= value <= 255'.  A distance value of 10
represents the distance to the node itself.  A distance value of 20
represents the default value for remote nodes but other values are
possible depending on the physical topology of the system.

When distances are not fully described, any missing sibling distance
values will default to 10 for local nodes and 20 for remote nodes.

If distance is given for A -> B, then we default B -> A to the same
value instead of 20.

010f88d5cb numa: avoid failure in nodememstats on non-NUMA systems
libvirt reports a fake NUMA topology in virConnectGetCapabilities
even if built without numactl support. The fake NUMA topology consists
of a single cell representing the host's cpu and memory resources.
Currently this is the case for ARM and s390[x] RPM builds.

A client iterating over NUMA cells obtained via virConnectGetCapabilities
and invoking virNodeGetMemoryStats on them will see an internal failure
"NUMA isn't available on this host" from virNumaGetMaxNode. An example
for such a client is VDSM.

Since the intention seems to be that libvirt always reports at least
a single cell it is necessary to return "fake" node memory statistics
matching the previously reported fake cell in case NUMA isn't supported
on the system.

config files missing an ending newline

https://www.redhat.com/archives/libvir-list/2017-October/msg01353.html

Commit 3cc2a9e0 fixed a similar problem when parsing content of a
file but missed parsing in-memory content. But AFAICT, the better
fix is to properly set the end of the content when initializing the
virConfParserCtxt in virConfParse().

This commit reverts the part of 3cc2a9e0 that appends a newline to
files missing it, and fixes setting the end of content when
initializing virConfParserCtxt. A test is also added to check
parsing in-memory content missing an ending newline.

3d899b9965 qemu-ns: Detect /dev/* mount point duplicates even better
In 4f15707202 I've tried to make duplicates detection for
nested /dev mount better. However, I've missed the obvious case
when there are two same mount points. For instance if:

  # mount --bind /dev/blah /dev/blah
  # mount --bind /dev/blah /dev/blah

Yeah, very unlikely (in qemu driver world) but possible.

0a3bae7d22 util: storage: Fix parsing of IPv6 portal address for iSCSI
Split on the last colon and avoid parsing port if the split remainder
contains the closing square bracket, so that IPv6 addresses are
interpreted correctly.

61ea70341a tests: Rename ppc64le caps to ppc64
The architecture itself is called ppc64, and it can run both in big
endian and little endian mode - the latter is known as ppc64le.

From the (virtual) hardware point of view, ppc64 is a more accurate
name so it should be used here.

fec8f9c49a qemu: Use predictable file names for memory-backend-file
In some cases management application needs to allocate memory for
qemu upfront and then just let qemu use that. Since we don't want
to expose path for memory-backend-file anywhere in the domain
XML, we can generate predictable paths. In this case:

  $memoryBackingDir/libvirt/qemu/$shortName/$alias

where $shortName is result of virDomainDefGetShortName().

bb3de478a6 qemu: Destroy whole memory tree
When removing path where huge pages are call virFileDeleteTree
instead of plain rmdir(). The reason is that in the near future
there's going to be more in the path than just files - some
subdirs. Therefore plain rmdir() is not going to be enough.
