cf88b13090 schema: add password configuration for ssh disk
Right now, ssh network disks are not usable. There is some basic support
in libvirt that is meant to support disk chains that have backing disks
located at ssh urls, but there is no real way for a user to configure a
ssh-based disk.  This commit allows users to configure an ssh disk with
password authentication. Implementation will follow.

<disk type='network'>
  <source  protocol='ssh' ...>
    <auth username='myusername'>
      <secret type='iscsi' usage='secretname'/>
    </auth>
</disk>

ca40725a21 manpage: virsh: Note that 'virsh undefine --remove-all-storage' doesn't remove backing images
Removing a backing image could break other image chains as it's
theoretically possible to share backing chains.

As --storage/--remove-all-storage is fully implemented in virsh as a
helper option, which enumerates and deletes VM's volumes. We do not plan
to make it any more complicated.

Document that backing chains are not removed.

7ba20863a7 meson: Annotate each test() with 'suite'
A test case can be part of a test suite (just like we already
have 'syntax-check'). This then allows developers to run only a
subset of tests. For instance - when using valgrind test setup
(`meson test -C _build/ --setup valgrind`) it makes zero sense to
run syntax-check tests or other script based tests (e.g.
check-augeas-*, check-remote_protocol, etc.). What does makes
sense is to run compiled binaries.

Strictly speaking, reaching that goal is as trivial as annotating
only those compiled tests (declared in tests/meson.build) and
running them selectively:

  meson test -C _build/ --setup valgrind --suite $TAG

But it may be also desirable to run test scripts separately.

Therefore, introduce two new tags: 'bin' for compiled tests, and
'script' for script based tests and annotate each test()
accordingly.

677156f662 conf: Introduce <address/> for virtio-mem and virtio-pmem
Both virtio-mem and virtio-pmem devices have '.memaddr' attribute
which controls the address where they are mapped in the guest
memory. Ideally, users do not need to specify this as QEMU does
the right thing and computes addresses automatically on startup.

But soon, we will need to record this address as it is part of
guest ABI. And also, there might be some users that want to
control this value. Now, we are in a bit of a pickle, because
both these device types already have a PCI address, therefore we
can't just use <address/> blindly. But what we can do, is
introduce <address/> under the <target/> element. This is also
more conceptual, as knobs under <target/> control guest visible
config of memory device (and .memaddr surely falls into that
category).

NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr
attribute, but because of the way we build cmd line there's no
(easy) way to set the attribute. So ignore that for now.

ac7f3667f2 meson: Work around configure_file(copy:true) deprecation
In our meson scripts, we use configure_file(copy:true) to copy
files from srcdir into builddir. However, as of meson-0.64.0,
this is deprecated [1] in favor of using:

  fs = import('fs')
  fs.copyfile(in, out)

Except, the submodule's new method wasn't introduced until
0.64.0. And since we can't bump the minimal meson version we
require, we have to work with both: new and old versions.

Now, the fun part: fs.copyfile() is not a drop in replacement as
it returns different type (a custom_target object). This is
incompatible with places where we store the configure_file()
retval in a variable to process it further.

While we could just replace 'copy:true' with a dummy
'configuration:...' (say 'configuration: configmake_conf') we
can't do that for binary files (like src/fonts/ or src/images/).

Therefore, places where we are not interested in the retval can
be switched to fs.copyfile() and places where we are interested
in the retval will just use a dummy 'configuration:'.

Except, src/network/meson.build. In here we not just copy the
file but also specify alternative install dir and that's not
something that fs.copyfile() can handle. Yet, using 'copy: true'
is viewed wrong [2].

d317d1d217 docs: Document requirements on format strings in translated messages
Preserving the order of format strings (%s, ...) when translating
messages may be very hard or even impossible depending on the target
language. On the other hand, reordering them requires understanding the
C-format strings which is not something we should expect from
translators. And even if someone reorders format strings in the right
way (by addressing arguments directly using N$), someone else may use a
translation tool that requires format strings in msgid and msgstr to
match exactly and forces these correct formats to be reverted.

As a result of this, we had several reported crashes in some locales
because integers were formatted as strings. So to make such crashes less
likely to happen and to make translating our messages easier, we now
require all messages that are marked for translation to use format
strings that always refer to the same argument no matter where they
appear in a message (e.g., %1$s, %5$llu).
