There are some platforms where 'char' is unsigned, by default
(RPi, s390x to name a few). And because of how test_demo is
written we are experiencing some test cases failing there. For
instance: /xdr/struct-scalar is failing. This is because in the
test (test_struct_scalar()), we have a struct with two chars. One
is initialized to 0xca, the other 0xfe (note that both have the
MSB set). The XDR encoder (xdr_TestStructScalar()) then calls
xdr_char() on both of them. But XDR itself has no notion of
char type, so under the hood, it expands it to int [1] and calls
xdr_int(). And this is where the problem lies. On platforms where
char is signed, the integer expansion results in 0xffffffca, but
on platforms where char is unsigned it results in 0x000000ca. Two
distinct results.
The test then goes and compares the encoded buffer with an
expected one (memcmp(), read from the disk earlier).
This poses no problem for real life use, because when decoding
those chars back, the padding is thrown away.
To avoid tickling this issue, use values that don't have the MSB
set.

The test_demo program compares whether XDR encoded data match the
expected output as read from a file. But the file path is not
absolute and thus relative to CWD which means the program can run
only from one specific directory.

QEMU allows and in cases where you omit the not-strictly-needed 'raw'
driver on top of raw images automatically uses the protocol name inside
of the 'backing file format' field of the qcow2 image.
Libvirt expects only format names in that field.
Add example images showing this scenario, which will be fixed later.
The qcow2 image files in this commit were formatted as:
qemu-img create -f qcow2 -F nbd -b nbd+tcp://example.org:6000/blah -u qcow2-protocol-backing-nbd.qcow2 10M
and
qemu-img create -f qcow2 -F file -b raw qcow2-protocol-backing-file.qcow2
thus using 'nbd' and 'file' as backing format respectively.
(note that '-b raw' refers to the file in the example image folder)
To satisfy the test, note that the NBD image is also rejected as we
can't probe it, thus such configuration would not work.

This is mostly straightforward, except for a teensy-weensy
detail: usually, there's no system wide daemon running, no system
wide available socket that anybody could connect to. PipeWire
uses a per user daemon approach instead. But this in turn means,
that the socket location floats between various locations and is
derived from various environment variables (just like the actual
socket name) and thus we must pass the variables to QEMU.

QEMU gained support for PipeWire audio backend (see QEMU commit
of v8.0.0-403-gc2d3d1c294). Its configuration knobs are basically
the same as pulseaudio's, except for PA's server name. Therefore,
a lot of code is copied over from pulseadio and fixed by
s/Pulse/Pipewire/ or s/pulseaudio/pipewire/.
There's one ley difference to PA though: pipewire daemon is
usually on per user basis (just like our qemu:///session).
Therefore, introduce this 'runtimeDir' attribute, which allows
specifying path to pipewire daemon socket (useful for
qemu:///system for instance).

On systems with humongous pages (16GiB) and 32bit int it's easy
to hit integer overflow in virNumaGetPages(). What happens is,
inside of virNumaGetPages() as we process hugepages for given
NUMA node (e.g. in order to produce capabilities XML), we keep a
sum of sizes of pools in an ULL variable (huge_page_sum). In each
iteration, the variable is incremented by 1024 * page_size *
page_avail. Now, page_size is just an uint, so we have:
ULL += U * U * ULL;
and because of associativity, U * U is computed first and since
we have two operands of the same type, no type expansion happens.
But this means, for humongous pages (like 16GiB) the
multiplication overflows.
Therefore, move the multiplication out of the loop. This helps in
two ways:
1) now we have ULL += U * ULL; which expands the uint in
multiplication,
2) it saves couple of CPU cycles.
