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.

- Adds creation of user chains via `-N <chainname>`
- Adds `-j RETURN` support for built-in chains, which triggers the
chain's underflow rule (usually the default policy).
- Adds tests for chain creation, default policies, and `-j RETURN' from
built-in chains.
The readme didn't mention that users need to:
- `bazel build` when working on iptables tests
- enable raw sockets in /etc/docker/daemon.json.

- 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

From RFC 793 s3.9 p58 Event Processing:
If RECEIVE Call arrives in CLOSED state and the user has access to such a
connection, the return should be "error: connection does not exist"
Fixes#1598

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.

* Tests are picked for a shard differently. It now picks one test from each
block, instead of picking the whole block. This makes the same kind of tests
spreads across different shards.
* Reduce the number of connect() calls in TCPListenClose.

If the support is Ignored, then the call is still executed. We
simply rely on it to fall through to the int3. Therefore, we
must also bail on the vendor check.

This avoids conflicting definitions of GetSocketPairs() in outer namespace when
multiple such cc files are complied for one binary.

When sending a RST on shutdown we need to double check the
state after acquiring the work mutex as the endpoint could
have transitioned out of a connected state from the time
we checked it and we acquired the workMutex.
I added two tests but sadly neither reproduce the panic. I am
going to leave the tests in as they are good to have anyway.

Splice must not allow negative offsets. Writes also must not allow offset +
size to overflow int64. Reads are similarly broken, but not just in splice
(b/148095030).

Special files can have additional requirements for granularity.
For example, read from eventfd returns EINVAL if a size is less 8 bytes.

And Type* over Type *. This is basically a whitespace only change.
gVisor code already prefers left-alignment of pointers and references, but
clang-format formats for consistency with the majority of a file, and some
files leaned the wrong way. This is a one-time pass to make us completely
conforming.
