Rather than try to describe what I was thinking about for the passing
the compress program directly series from Chen Hanxiao:

http://www.redhat.com/archives/libvir-list/2016-September/msg00677.html

and

http://www.redhat.com/archives/libvir-list/2016-August/msg01237.html

I took the liberty of creating my own set of patches which should end
in the more or less same result.

The primary benefit is not calling virFileInPath twice since we already
get it at least once for the various compressed program callers, let's
pass what we originally found.

John Ferlan (7):
  qemu: Move getCompressionType
  qemu: Adjust doCoreDump to call getCompressionType
  qemu: Introduce helper qemuGetCompressionProgram
  qemu: Remove getCompressionType
  qemu: Use qemuGetCompressionProgram for error paths
  qemu: Remove qemuCompressProgramAvailable
  qemu: Get/return compressedpath program
