switch the stdin half of the waiter to waiting for either socket write

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.

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!

All CBC ciphers in TLS are broken and insecure. TLS 1.2 introduced
AEAD-based ciphers which avoid their many problems. It also introduced
new CBC ciphers based on HMAC-SHA256 and HMAC-SHA384 that share the same
flaws as the original HMAC-SHA1 ones. These serve no purpose. Old
clients don't support them, they have the highest overhead of all TLS
ciphers, and new clients can use AEADs anyway.
Remove them from libssl. This is the smaller, more easily reverted
portion of the removal. If it survives a week or so, we can unwind a lot
more code elsewhere in libcrypto. This removal will allow us to clear
some indirect calls from crypto/cipher_extra/tls_cbc.c, aligning with
the recommendations here:

free to shed the handshake configuration at TLS 1.3 or HTTP/2.
Rather than making config shedding implicitly disable renegotiation,
make the actual shedding dependent on a combination of the two settings.
If config shedding is enabled, but so is renegotiation (including
whether we are a client, etc.), leave the config around. If the
renegotiation setting gets disabled again after the handshake,
re-evaluate and shed the config then.

|SSL_CONFIG| is a container for bits of configuration that are
unneeded after the handshake completes. By default it is retained for
the life of the |SSL|, but it may be shed at the caller's option by
calling SSL_set_shed_handshake_config(). This is incompatible with
renegotiation, and with SSL_clear().
|SSL_CONFIG| is reachable by |ssl->config| and by |hs->config|. The
latter is always non-NULL. To avoid null checks, I've changed the
signature of a number of functions from |SSL*| arguments to
|SSL_HANDSHAKE*| arguments.
When configuration has been shed, setters that touch |SSL_CONFIG|
return an error value if that is possible. Setters that return |void|
do nothing.
Getters that request |SSL_CONFIG| values will fail with an |assert| if
the configuration has been shed. When asserts are compiled out, they
will return an error value.
The aim of this commit is to simplify analysis of split-handshakes by
making it obvious that some bits of state have no effects beyond the
handshake. It also cuts down on memory usage.
Of note: |SSL_CTX| is still reachable after the configuration has been
shed, and a couple things need to be retained only for the sake of
post-handshake hooks. Perhaps these can be fixed in time.

Replace them with asserts and better justify why each of the internal
cases are not reachable. Also change the loop to count up to bits+1 so
it is obvious there is no memory error. (The previous loop shape made
more sense when ec_compute_wNAF would return a variable length
schedule.)

Along the way, add some utility functions for getting common things
(curves, hashes, etc.) in the names Wycheproof uses.

FileTest and Wycheproof express more-or-less the same things, so I've
just written a script to mechanically convert them. Saves writing a JSON
parser.
I've also left a TODO with other files that are worth converting. Per
Thai, the webcrypto variants of the files are just a different format
and will later be consolidated, so I've ignored those. The
curve/hash-specific ECDSA files and the combined one are intended to be
the same, so I've ignored the combined one. (Just by test counts, there
are some discrepancies, but Thai says he'll fix that and we can update
when that happens.)

Chromium has some code which reaches into this field for memory
accounting.
This fixes a bug in doc.go where this line-wrapping confuses it. doc.go
needs a bit of a rewrite, but this is a bit better.

This is just a pristine copy of the JSON files for now. It's not hooked
up to anything yet.
