[mkgmap-dev] Commit r4556: route1.patch by Steve Ratcliffe (modified)

Version mkgmap-r4556 was committed by gerd on Thu, 09 Jul 2020 route1.patch by Steve Ratcliffe (modified) - reverts the size improvements introduced with r4360, but seems to improve routing on devices - I added undocumented option --x-no-force-end-nodes-routing-nodes which can be used to get the previous behaviour of r4555 http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4556
