Here's some patches that cleans up debug-printing in virgl a bit, by
using the existing debug environment-variable infrastructure so things
can be turned on and off explicitly.

This version introduce two flags:
- verbose: enables verbose output. This is useful to get information on
  some internal details, which would usually be overly chatty.
- tgsi: outputs the textual TGSI representation. This is useful for
  debugging virglrenderer when it's often useful to see what TGSI
  triggered for instance a malformed shader.

Both of these are flags for the VIRGL_DEBUG environement variable.

Erik Faye-Lund (4):
  virgl: delete commented out fprintf-call
  virgl: replace fprintf-call with debug_printf
  virgl: introduce $VIRGL_DEBUG=verbose
  virgl: add debug-switch to output TGSI
