[or-cvs] Split mark-dir-failed-and-retry logic into separate functio...



Update of /home/or/cvsroot/tor/src/or
In directory moria.mit.edu:/tmp/cvs-serv29357/src/or

Modified Files:
	connection.c directory.c or.h 
Log Message:
Split mark-dir-failed-and-retry logic into separate function; make it retry runningrouters as well as directory fetches; note that the do-we-need-to-give-up test is wrong.
