While it's true that our virCommand subsystem is happy with
non-absolute paths, the dnsmasq capability code is not. It stores
the path to dnsmasq within and makes it accessible via
dnsmasqCapsGetBinaryPath(). While strictly speaking no caller
necessarily needs canonicalized path, let's find dnsmasq once and
cache the result.
Therefore, when constructing the capabilities structure look up
the binary path. If DNSMASQ already contains an absolute path
then virFindFileInPath() will simply return a copy.
With this code in place, the virFileIsExecutable() check can be
removed from dnsmasqCapsRefreshInternal() because
virFindFileInPath() already made sure the binary is executable.
But introducing virFindFileInPath() means we have to mock it in
test suite because dnsmasqCaps are created in
networkxml2conftest.
Moreover, we don't need to check for dnsmasq in configure.

This commit declares g_autoptr() function for virConfValue type.
At the same time, it switches variable declarations to use it.
Also, in a few places we might have freed a variable twice, for
instance in xenFormatXLDomainNamespaceData(). This is because
virConfSetValue() consumes passed pointer (@value) even in case
of failure and thus any code that uses virConfSetValue() must
refrain from touching @value and it must not call
virConfFreeValue().
