c4cd0ef917 spec: Don't require mdevctl on RHEL 7
mdevctl is a relatively new tool that's packaged for Fedora and
RHEL 8, but not for RHEL 7. Make the dependency conditional to
avoid the libvirt-daemon-driver-nodedev package becoming
uninstallable on that platform.

0dcf9562e2 virNetSocketCheckProtocols: Actually check bool value
In 9536379da4 and 8b0cb0e666 I've tried to call
virNetSocketCheckProtocolByLookup() only if we are suspecting the
host is IPv4 or IPv6 capable (because we've found an interface
with such address). However, the code was missing dereference of
the boolean variables and thus was comparing pointers against
NULL.

7d488a7c45 Partially revert "qemu: fix missing error reports in capabilities probing"
This partially reverts commit 5331c4804f.

The original commit mistakenly thought virFileCacheLookup did not set
an error. In fact the only case it doesn't set an error for is when
the cache key is NULL. This in fact the fault of the caller for passing
an invalid cache key, so doesn't need to be handled.

This caller bug was fixed by checking for a NULL binary in the
virQEMUCapsCacheLookupDefault method.

8b0cb0e666 virNetSocketCheckProtocols: Confirm IPv4 by lookup too
Historically, if we found an interface with an IPv6 address we
did not blindly trust that host is IPv6 capable (as in we can
successfully translate IPv4 addresses) but used getaddrinfo() to
confirm it. Turns out, we have use the same argument for IPv4.
For instance, in an namespace created by the following steps,
getaddrinfo("127.0.0.1", ...) fails (demonstrating by "Socket
TCP/IPv4 Accept" test case failing in virnetsockettest):

  unshare -n
  ip link set lo up

e146f4beef virNetSocketCheckProtocols: Separate out checking family via getaddrinfo()
The virNetSocketCheckProtocols() function is supposed to tell
caller whether IPv4 and/or IPv6 is supported on the system. In
the initial round, it uses getifaddrs() to see if an interface
has IPv4/IPv6 address assigned and then to double check IPv6 it
uses getaddrinfo() to lookup IPv6 loopback address. Separate out
this latter code because it is going to be reused.

Since the original code lived under an #ifdef and the new
function doesn't it is marked as unused - because on some systems
it may be so.

kept the old alias just for API stability. Well, not anymore [2].
