1. Previously, a DSA area would create up to four segments at each size before doubling the size. After this commit, it will create only two at each size, so it ramps up faster and therefore needs fewer slots. 2. Previously, the total limit on DSM slots allowed for 2 per connection. Switch to 5 per connection. This back-patches commit d061ea21 from release 13 into 10-12 based on a field complaint.
