As part of an goal to eliminate Perl from libvirt build tools,
rewrite the hvsupport.pl tool in Python.
This was a straight conversion, manually going line-by-line to
change the syntax from Perl to Python. Thus the overall structure
of the file and approach is the same.
The new impl generates byte-for-byte identical output to the
old impl.
