[master] automatically tune max-journal-size

Browse Source 
4613.	[func]		By default, the maximum size of a zone journal file
			is now twice the size of the zone's contents (there
			is little benefit to a journal larger than this).
			This can be overridden by setting "max-journal-size"
			to "unlimited" or to an explicit value up to 2G.
			Thanks to Tony Finch. [RT #38324]
