The code which opens the VDPA device and prepares it for FD passing was
not called in the hotplug code path, preventing hotplug of VDPA disks
with:
error: internal error: argument key 'path' must not have null value
Use the new helper qemuProcessPrepareHostStorageDisk to setup the VDPA
definition.

Currently the code sets up only VDPA backends but will be used later in
hotplug code too.
This patch also uses normal forward iteration in the loop in
qemuProcessPrepareHostStorage as we don't need to remove disks from the
disk list at that point.

Given that this variable now controls not just whether C tests
are built, but also whether any test at all is executed, the new

Currently, passing -Dtests=disabled only disables a subset of
tests: those that are written in C and thus require compilation.
Other tests, such as the syntax-check ones and those that are
implemented as scripts, are always enabled.
There's a potentially dangerous consequence of this behavior:
when tests are disabled, 'meson test' will succeed as if they
had been enabled. No indication of this will be shown, so the
user will likely make the reasonable assumption that everything
is fine when in fact the significantly reduced coverage might
be hiding failures.
To solve this issues, disable *all* tests when asked to do so,
and inject an intentionally failing test to ensure that 'meson
test' doesn't succeed.
Best viewed with 'git show -w'.

It's somewhat confusing that some of the services have a
corresponding foo.service.extra.in and foo.socket.extra.in, some
have just one of the two, and some have neither.
In order to make things more approachable, make sure that both
files exists for each service.
In most cases the extra units are currently unused, so they will
just contain a comment briefly explaining their purpose and
pointing users to meson.build, where they can find more
information. The same comment is also added to the top of
extra units that already have some contents in them for
consistency.
