* Change default value to 1232
As specified by DNS flag day 2020, good and decent default value
avoiding fragmentation issues should be 1232. It is quite likely 1500
would work reliably on local ethernet networks.
Value 512 is set implicitly and must be used for all clients, which did
not include OPT RR with explicit value they support.
Since MR #5368 it should work correctly.

* Update bufsize documentation
Mention also increasing request size is not possible, it can only reduce
the accepted size.
