QPID-504: Print bound port if --port 0 is specified. Not yet used by tests.

	* qpidd.cpp:
	 - With --port 0 print the bound port number to stdout.
	 - Removed --ppid, --check now prints pid.

	* Daemon.cpp/h: Move pid-file generation to caller (qpidd.cpp)

	* Exception.cpp: Log a debug message in exception constructors.
	  Helps to show what exceptions were thrown even if they aren't
	  logged at a higher level. 

	* daemon_test: Test new daemon options.
