[libvirt] [PATCH 0/4] Speed up hvsupport.pl

This reduces the script execution time from 14.7s to 60 ms. Since this was by far the longest taking target from the docs/ directory and make does not parallelize across Makefiles, the savings are similar for a complete build from a fresh git checkout. The second patch shaves off 8.2s, the third 6.4s and the last one shaves off half of the remaining time.
