Actually, I'm turning this function into a macro as filename,
function name and line number needs to be passed. The new
function virAsprintfInternal is introduced with the extended set
of arguments.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

Certain functions in the sysinfotest.c are not used unless
a whitelisted architecture is being built. Disable those
functions unless required to avoid warnings about unused
functions.

Test cases for virSysinfoRead. Initially, there are tests for
x86 (DMI based) and s390 (/proc/... based).
In lack of PPC data, I have stubbed out the test for it, but it
can be added with a minimal effort.
