This adds helpers to send both of these control messages via sendmsg,
and most of the initialization is moved into the SetUp body.
The parametrization is now more meaningful. The kDualStack is actually
impactful, which means DifferentTOSAndTClass test has been removed. The
IPv4-mapped IPv6 scenario is now tested in the SetAndReceiveTOSOrTClass.

- Inline `IfAddrHelper` into its sole user
- Implement pretty-printing `sockaddr_ll`
- Make test class members private, add const accessors
- Log all interface addresses on SetUp for b/137899561
Simplify some things while I'm here.

A raw IP endpoint's write and socket option get/set path can use the
datagram-based endpoint.
This change extracts tests from UDP that may also run on Raw IP sockets.
Updates #6565.
Test: Raw IP + datagram-based socket syscall tests.

Code to get the loopback interface's index is scattered throughout the
syscall tests. Implement the code once and use that in tests (where
applicable).
While I am here, trim the dependencies/includes for network namespace
tests.

Added the ability to get/set the IP_RECVTCLASS socket option on UDP endpoints.
If enabled, traffic class from the incoming Network Header passed as ancillary
data in the ControlMessages.
Adding Get/SetSockOptBool to decrease the overhead of getting/setting simple
options. (This was absorbed in a CL that will be landing before this one).
Test:
* Added unit test to udp_test.go that tests getting/setting as well as
verifying that we receive expected TOS from incoming packet.
* Added a syscall test for verifying getting/setting
* Removed test skip for existing syscall test to enable end to end test.

Tests 65k connection attempts on common types of sockets to check for port
leaks.
Also fixes a bug where dual-stack sockets wouldn't properly re-queue
segments received while closing.

These are currently duplicated in ip_socket_test_util, so tests including
both netinet/tcp.h and ip_socket_test_util won't compile.

This change adds support for the SO_BROADCAST socket option in gVisor Netstack.
This support includes getsockopt()/setsockopt() functionality for both UDP and
TCP endpoints (the latter being a NOOP), dispatching broadcast messages up and
down the stack, and route finding/creation for broadcast packets. Finally, a
suite of tests have been implemented, exercising this functionality through the
Linux syscall API.

Also includes a few fixes for IPv4 multicast support. IPv6 support is coming in
a followup CL.
