It's a common pattern in test code to reinterpret_cast<sockaddr*> from
sockaddr_* structs. Make AsSockAddr() for them so code looks better.
Note: Why not a wrapper type for `sockaddr_storage` and etc?
It's also a common need to have a local in-out variable of socklen_t.
Creating a wrapper type may however lead to this wrong code:
Wrapper addr;
socklen_t addrlen = sizeof(addr);
where sizeof(Wrapper) may not equal to sizeof(sockaddr_storage).

IPv4 previously accepts the packet, while IPv6 panics. Neither is the behavior
in Linux.
splice() in Linux has different behavior than in gVisor. This change documents
it in the SpliceTooLong test.

IPv4 was always supported but UDP never supported joining/leaving IPv6
multicast groups via socket options.
Add: IPPROTO_IPV6, IPV6_JOIN_GROUP/IPV6_ADD_MEMBERSHIP
Remove: IPPROTO_IPV6, IPV6_LEAVE_GROUP/IPV6_DROP_MEMBERSHIP
Test: integration_test.TestUDPAddRemoveMembershipSocketOption

Handle "Resource temporarily unavailable" EAGAIN errors with a select
call before calling recvmsg.
Also rename similar helper call from "RecvMsgTimeout" to "RecvTimeout",
because it calls "recv".

`recv` calls with MSG_DONTWAIT can fail with EAGAIN randomly
in tests. Fix this by calling `select` on sockets with a timeout
prior to attempting a `recv`.

It was added in cl/201419897 to deflake
socket_ip_tcp_loopback_non_blocking_test_gvisor.
It seems we don't need this hack, because the origin issue isn't
reproducible without this hack.

- Move shared helpers V4Multicast and V4Broadcast to socket_test_util
- Add unnamed namespace so socket_ipv4_tcp_unbound_external_networking_test.cc
and socket_ipv4_udp_unbound_external_networking_test.cc can be compiled
together
- Add test files to "exports_files" so they can be included by Fuchsia's syscall
test setup

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.

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.
