net: core: Support UID-based routing.
This contains the following commits:
1. cc2f522 net: core: Add a UID range to fib rules.
2. d7ed2bd net: core: Use the socket UID in routing lookups.
3. 2f9306a net: core: Add a RTA_UID attribute to routes.
This is so that userspace can do per-UID route lookups.
4. 8e46efb net: ipv6: Use the UID in IPv6 PMTUD
IPv4 PMTUD already does this because ipv4_sk_update_pmtu
uses __build_flow_key, which includes the UID.
Bug: 15413527
