Subject: Add python methods for checking pending signals from rpmsqCaught. - a
 thin wrapper for rpmdbCheckSignals() from rpm5.org / Jeff Johnson - a
 function taking a list of signals to check and returning list caught  
 signals (python doesn't know about signal sets so rpmsqCaught needs  
 wrapping)
