V2_beta_1
	Many changes to address memory leaking and flushing, including:

		New parent class that manages the usage trackers. This class
		has been validated stand-alone for leakage and derived 
		for the trackers.
		Thread safe functions are used for hostname and inet conversions.
		A flush mode has been added '-F mins' to flush long standing
		connections (these were a major source of process growth). 
		This time is quantised to the appropriate minute. For example,
		-F 3600 means flush the list once an hour on the hours.

		The schema has been updated to indicate this record is a result of 
		a timed flush and could be a continuing connection.

		Lots of other small changes but these are the most important.
		
		Upgrade to postgres 7.4 needs a new library.
		Thread compiler flags are generated by acx_pthread.m4

		TODO: using bpf filters the actual traffic for matched sessions
		will be saved to the database. Some work done.

	in particular:
		background mode -b

		dns table expiry.
