Improve performance of UDPMux map lookups

Browse Source 
UDPMux is using a map to lookup addresses of each packets.
Unfortunately the key is based on a string and each time we
want to check the map, a conversion of the UDP address to string
is made (.String()) which is expensive.

This CR replace the string key by a binary key called ipPort. This
structure contains a netip.Addr field and ipPort could be used as
a map key
