Problem description

Treat ports below 512 as reserved ports.
Though applications trying to bind a reserved port normally look in the range 512-1024 (because below there is very dense with well known ports), all ports 1-1024 are reserved in that only root can bind to them. So when checking if a port is 'reserved' we should allow it anywhere in the full range.
This allows sunrpc.minresvport to be set low and portmap will still allow mappings made by the kernel.
