  I had kept them because they gave more contextual informations, but
  basically if there isn't enough memory, it's not worth bothering
  really.

So I made all the changes and commited, thanks !

One thing we noticed is that if someone disable debug with
--disable-debug then all errors/warnings/info which are reported
directly via VIR_ERROR/VIR_WARN/VIR_INFO disapear as the logging
code is not compiled in. We need to change this, logging code should
not be made optional and --disable-debug should just redefine the
VIR_DEBUG* macros to noop, but the rest of the logging infrastructure
should still be activated.
This will have to be addressed in a separate patch,

Daniel
