ip_quadruple/proxy: make port uint16_t

Browse source 
Make `port` member in these struct of type `uint16_t`.

add `uint8_t transport` to `struct ip_quadruple

Define TRNSPRT_NONE as 0. By assigning a valid transport only on a
successful connection, it is clear when the ip_quadruple members are
valid. Also, for transports not involving ports, the getinfos for
`CURLINFO_PRIMARY_PORT` and `CURLINFO_LOCAL_PORT` will now always return
-1.

Make all `transport` members and parameters of type `uint8_t`.

Document the return value of `CURLINFO_LOCAL_PORT` and
`CURLINFO_PRIMARY_PORT` in this regard. Add tests that writeout stats
report ports correctly.

Closes #19708
