log_manager.cc :

tuned error printing and log writing output format
dcb.c : 
	dcb_connect, check return value of poll_add_dcb and behave accordingly.
	dcb_write, in case of SIFPIPE, only write to trace log.
	dcb_close, dassert with incorrect dcb states.
gateway.c :
	added file_write_header to print header similar than in logs to stderr.
	main, add signal handler for SIGPIPE
poll.c : 
	poll_remove_dcb, don't fail if dcb is in NOPOLLING or in ZOMBIE states.
	poll_waitevents, write EPOLLHUPs to trace log, don't even attempt to write to closed socket.
readconnection.h : 
	shortened comment.
readwritesplit.h : 
	replaced generic names with more specific ones. 
httpd.c : 
	Check listen return value and behave accordingly.
mysql_backend.c : 
	 Tiny clean up.
mysql_client.c : 
	gw_MySQLListener, Check listen return value and behave accordingly. 
mysql_common.c : 
	Shortened a header.
telnetd.c : 
	telnetd_listen, check listen return value and behave accordingly.
readconnroute.c : 
	Tuned log writing format.
readwritesplit.c : 
	Added function search_backend_servers, which chooses suitable backend and master server among those known by Maxscale. Fixed clean-up routines. Not ready yet but works somehow.
testroute.c : 
	Cleanup.
skygw_utils.cc : 
	Log writing clean up.
