Test both asynchronous and synchronous versions. This callback is somewhat
different from others. It's NOT called a second time when the handshake is
resumed. This appears to be intentional and not a mismerge from the internal
patch. The caller is expected to set up any state before resuming the handshake
state machine.
Also test the early callback returning an error.

This involves more synchronization with child exits as the kernel no longer
closes the pre-created pipes for free, but it works on Windows. As long as
TCP_NODELAY is set, the performance seems comparable. Though it does involve
dealing with graceful socket shutdown. I couldn't get that to work on Windows
without draining the socket; not even SO_LINGER worked. Current (untested)
theory is that Windows refuses to gracefully shutdown a socket if the peer
sends data after we've stopped reading.
cmd.ExtraFiles doesn't work on Windows; it doesn't use fds natively, so you
can't pass fds 4 and 5. (stdin/stdout/stderr are special slots in
CreateProcess.) We can instead use the syscall module directly and mark handles
as inheritable (and then pass the numerical values out-of-band), but that
requires synchronizing all of our shim.Start() calls and assuming no other
thread is spawning a process.
PROC_THREAD_ATTRIBUTE_HANDLE_LIST fixes threading problems, but requires
wrapping more syscalls. exec.Cmd also doesn't let us launch the process
ourselves. Plus it still requires every handle in the list be marked
inheritable, so it doesn't help if some other thread is launching a process
with bInheritHandles TRUE but NOT using PROC_THREAD_ATTRIBUTE_HANDLE_LIST.
(Like Go, though we can take syscall.ForkLock there.)

The more natively Windows option seems to be named pipes, but that too requires
wrapping more system calls. (To be fair, that isn't too painful.) They also
involve a listening server, so we'd still have to synchronize with shim.Wait()
a la net.TCPListener.
Then there's DuplicateHandle, but then we need an out-of-band signal.
All in all, one cross-platform implementation with a TCP sockets seems
simplest.

I found no users of this. We can restore it if needbe, but I don't expect
anyone to find it useful in its current form. The API is suspect for the same
reasons DTLSv1_listen was. An SSL object is stateful and assumes you already
have the endpoint separated out.
If we ever need it, server-side HelloVerifyRequest and DTLSv1_listen should be
implemented by a separate stateless listener that statelessly handles
cookieless ClientHello + HelloVerifyRequest. Once a ClientHello with a valid
cookie comes in, it sets up a stateful SSL object and passes control along to
that.

The new V2ClientHello sniff asserts, for safety, that nothing else has
initialized the record layer before it runs. However, OpenSSL allows you to
avoid explicitly calling SSL_connect/SSL_accept and instead let
SSL_read/SSL_write implicitly handshake for you. This check happens at a fairly
low-level in the ssl3_read_bytes function, at which point the record layer has
already been initialized.
Add some tests to ensure this mode works.
(Later we'll lift the handshake check to a higher-level which is probably
simpler.)

The minimum MTU (not consistently enforced) is just under 256, so it's
difficult to test everything, but this is a basic test. (E.g., without renego,
the only handshake message with encryption is Finished which fits in the MTU.)
It tests the server side because the Certificate message is large enough to
require fragmentation.

The ClientHello record is padded to 1024 bytes when
fastradio_padding is enabled. As a result, the 3G cellular radio
is fast forwarded to DCH (high data rate) state. This mechanism
leads to a substantial redunction in terms of TLS handshake
latency, and benefits mobile apps that are running on top of TLS.

they will provide test coverage later for configuring features when using the

Notably, this would have caught ed8270a55c
(although, apart from staring at code coverage, knowing to set resumeSession on
the server test isn't exactly obvious). Perhaps we should systematically set it
on all extension server tests; ClientHello extension parsing happens after
resumption has been determined and is often sensitive to it.
