  hwcontext_vaapi : Add driver quirks to the hwdevice
  The driver being used is detected inside av_hwdevice_ctx_init() and
  
  the quirks field then set from a table of known device.  If this
  
  behaviour is unwanted, the user can also set the quirks field
  
  manually.
  Also adds the Intel i965 driver quirk (it does not destroy parameter
  
  buffers used in a call to vaRenderPicture()) and detects that driver
  
  to set it.
  (cherry picked from commit 4926fa9a4aa03f3b751f52e900b9efb87fea0591)

  vaapi_encode : Respect driver quirks around buffer destruction
  No longer leaks memory when used with a driver with the "render does
  
  not destroy param buffers" quirk (i.e. Intel i965).
  (cherry picked from commit 221ffca6314ed3ba9d38464ea50cd85251c04e74)
  
  Fixes ticket #5871.
