On Windows, just switching the socket to blocking doesn't work. Instead,
switch the stdin half of the waiter to waiting for either socket write
or stdin read, depending on whether we're in the middle of trying to
write a buffer.

If the peer sends us one record that exceeds buffer, the socket will no
longer flag as readable, because data has been consumed, but SSL_read
should still be called to drain data. bssl would instead not notice and
only surface the data later on.
This can (currently) be reproduced by sending "HEAD / HTTP/1.1" to
www.google.com.

While |WaitForMultipleObjects| works for both sockets and stdin, the
latter is often a line-buffered console. The |HANDLE| is considered
readable if there are any console events available, but reading blocks
until a full line is available. (In POSIX, line buffering is implemented
in the kernel via termios, which is differently concerning, but does
mean |select| works as expected.)
So that |Wait| reflects final stdin read, we spawn a stdin reader thread
that writes to an in-memory buffer and signals a |WSAEVENT| to
coordinate with the socket. This is kind of silly, but it works.
I tried just writing it to a pipe, but it appears
|WaitForMultipleObjects| does not work on pipes!

Rather than printing the SSL_ERROR_* constants, print the actual error.
This should be a bit more understandable. Debugging this also uncovered
some other issues on Windows:
- We were mixing up C runtime and Winsock errors, which are separate in
Windows.
- The thread local implementation interferes with WSAGetLastError due to
a quirk of TlsGetValue. This could affect other Windows consumers.
(Chromium uses a custom BIO, so it isn't affected.)
- SocketSetNonBlocking also interferes with WSAGetLastError.
- Listen for FD_CLOSE along with FD_READ. Connection close does not
signal FD_READ. (The select loop only barely works on Windows anyway
due to issues with stdin and line buffering, but if we take stdin out
of the equation, FD_CLOSE can be tested.)

https://boringssl-review.googlesource.com/10522 didn't actually do what
it was supposed to do. In fact, it appears, not paying attention to it,
we've managed to make RSA verify slower than ECDSA verify. Oops.
Did 32000 RSA 2048 verify (same key) operations in 1016746us (31473.0 ops/sec)
Did 5525 RSA 2048 verify (fresh key) operations in 1067209us (5177.1 ops/sec)
Did 8957 ECDSA P-256 verify operations in 1078570us (8304.5 ops/sec)
The difference is in setting up the BN_MONT_CTX, either computing R^2 or n0.
I'm guessing R^2. The current algorithm needs to be constant-time, but we can
split out a variable-time one if necessary.

TLS 1.3 deployment is currently blocked by buggy middleboxes
throughout the ecosystem. As an experiment to better understand these bugs
and the problems they are causing, implement TLS 1.3 variants with
alternate encodings. These are still the same protocol, only encoded
slightly differently. We will use what we learn from these experiments to
guide the TLS 1.3 deployment strategy and proposals to the IETF, if any.
These experiments only target the basic 1-RTT TLS 1.3 handshake. Based on
what we learn from this experiment, we may try future variations to
explore 0-RTT and HelloRetryRequest.
When enabled, the server supports all TLS 1.3 variants while the client
is configured to use a particular variant.

Both Conscrypt and Netty have a lot of logic to map between the two
kinds of names. WebRTC needed an SSL_CIPHER_get_rfc_name for something.
Just have both in the library. Also deprecate SSL_CIPHER_get_rfc_name
in favor of SSL_CIPHER_standard_name, which matches upstream if built
with enable-ssl-trace. And, unlike SSL_CIPHER_get_rfc_name, this does
not require dealing with the malloc.
(Strangely this decreases bssl's binary size, even though we're carrying
more strings around. It seems the old SSL_CIPHER_get_rfc_name was
somewhat large in comparison. Regardless, a consumer that disliked 30
short strings probably also disliked the OpenSSL names. That would be
better solved by opaquifying SSL_CIPHER and adding a less stringy API
for configuring cipher lists. That's something we can explore later if
needed.)
I also made the command-line tool print out the standard names since
they're more standard. May as well push folks towards those going
forward.

This imports upstream's scrypt implementation, though it's been heavily
revised. I lost track of words vs. blocks vs. bigger blocks too many
times in the original code and introduced a typedef for the fixed-width
Salsa20 blocks. The downside is going from bytes to blocks is a bit
trickier, so I took advantage of our little-endian assumption.
This also adds an missing check for N < 2^32. Upstream's code is making
this assumption in Integerify. I'll send that change back upstream. I've
also removed the weird edge case where a NULL out_key parameter means to
validate N/r/p against max_mem and nothing else. That's just in there to
get a different error code out of their PKCS#12 code.
Performance-wise, the cleanup appears to be the same (up to what little
precision I was able to get here), but an optimization to use bitwise
AND rather than modulus makes us measurably faster. Though scrypt isn't
a fast operation to begin with, so hopefully it isn't anyone's
bottleneck.
This CL does not route scrypt up to the PKCS#12 code, though we could
write our own version of that if we need to later.
