6a077cf2b3 tests/domaincaps: Use testQemuCapsIterate()
Now that the only data we need for fully testing a QEMU binary is
the (version, arch) combo, we can stop providing that information
ourselves and instead rely on testQemuCapsIterate() automatically
picking up new input files as they are added to the repository,
the same way the qemucapabilities and qemucaps2xml tests already
behave.

Unsurprisingly, this change results in a bunch of extra output
files being created, significantly expanding our test coverage.

79a14412b2 tests/domaincaps: Make test matrix programmatic
For each QEMU version there are usually several different,
architecture-dependedn scenarios that we're interested in testing;
however, since the test matrix has to be explicitly created by
calling DO_TEST_QEMU() multiple times with different arguments, we
end up with spotty coverage.

Fix this by implementing the arch-specific rules in code, which
result in the full coverage for a (version, arch) combo being
automatically achieved with a single call to DO_TEST_QEMU().

Unsurprisingly, this change results in a bunch of extra output
files being created.

5457af097d tests/domaincaps: Don't require redundant information
The full name of the test case, as well as the name of the QEMU
binary and corresponding capabilities file, can all be derived
from other information passed to the test, so there's no point in
asking the user to provide them.

12e42f1b2b tests/domaincaps: Move most of DO_TEST_QEMU() into a function
Macros become less and less appealing the more work you perform
inside them: DO_TEST_QEMU() has arguably already crossed that
threshold, and we're going to add even more code later on.

While factoring the code out of the macro, convert it to use the
GLib string manipulation functions and take advantage of autofree.

c4d6465aa7 tests: testQemuCapsIterate: Pass prefix and version to callback
Right now we're passing a "base" string that contains both,
separated by an underscore. Some changes that we're going to
introduce later will require us to have the version number on its
own, and instead of delegating the task of splitting the two apart
to the callback it make more sense to perform it upfront.

This change results in quite a bit of churn because we're now
using the version number only, without the prefix, to calculate
the dummy microcodeVersion.

5a45ed9c96 tests: testQemuCapsIterate: Pass suffix to callback
Right now users need to hardcode the suffix, which is not a big
deal since they're the ones who passed it to testQemuCapsIterate()
in the first place; however, since we're already passing most of
the information to the callback and we're going to add more later
on, it makes sense to be consistent and pass the suffix too.

3b4df5d350 Drop needless ret variable
In few places we have the following code pattern:

  int ret;
  ... /* @ret is not accessed here */
  ret = f(...);
  return ret;

This pattern can be written less verbose:

  ...
  return f(...);

This patch was generated with following coccinelle spatch:

  @@
  type T;
  constant C;
  expression f;
  identifier ret;
  @@
  -T ret = C;
   ... when != ret
  -ret = f;
  -return ret;
  +return f;

Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

9e9d78057d src: Don't rely on virAsprintf() returning string length
In a few places our code relies on the fact that virAsprintf()
not only prints to allocated string but also that it returns the
length of that string. Fortunately, only few such places were
identified:

  https://www.redhat.com/archives/libvir-list/2019-September/msg01382.html

In case of virNWFilterSnoopLeaseFileWrite() and virFilePrintf()
we can use strlen() right after virAsprintf() to calculate the
length. In case of virDoubleToStr() it's only caller checks for
error case only, so we can limit the set of returned values to
just [-1, 0].

c8007fdc5d domain_conf: Relax SCSI addr used check
In domain_conf.c we have virDomainSCSIDriveAddressIsUsed()
function which returns true or false if given drive address is
already in use for given domain config or not. However, it also
takes a shortcut and returns true (meaning address in use) if the
unit number equals 7. This is because for some controllers this
is reserved address. The limitation comes mostly from vmware and
applies to lsilogic, buslogic, spapr-vscsi and vmpvscsi models.
On the other hand, we were not checking for the maximum unit
number (aka LUN number) which is also relevant and differs from
model to model.
