In 1.1.0 s_server if the PSK identity doesn't match what we have then
a warning is printed and we continue the connection anyway. In 1.1.1,
if TLSv1.3 is used and the identity doesn't match then we abort the
connection. We should really be consistent with the old behaviour.

Previoulsy we just had max_early_data which controlled both the value of
max early_data that we advertise in tickets *and* the amount of early_data
that we are willing to receive from clients. This doesn't work too well in
the case where we want to reduce a previously advertised max_early_data
value. In that case clients with old, stale tickets may attempt to send us
more early data than we are willing to receive. Instead of rejecting the
early data we abort the connection if that happens.
To avoid this we introduce a new "recv_max_early_data" value. The old
max_early_data becomes the value that is advertised in tickets while
recv_max_early_data is the maximum we will tolerate from clients.

The problematic case falls back to a NULL conf which returns the result
of getenv(2). If this returns NULL, everything was good. If this returns
a string an attempt to convert it to a number is made using the function
pointers from conf.
This fix uses the strtol(3) function instead, we don't have the
configuration settings and this behaves as the default would.

1. For every named curve, two "golden" keypair positive tests.
2. Also two "golden" stock ECDH positive tests.
3. For named curves with non-trivial cofactors, additionally two "golden"
ECC CDH positive tests.
4. For named curves with non-trivial cofactors, additionally two negative
tests.
There is some overlap with existing EVP tests, especially for the NIST
curves (for example, positive testing ECC CDH KATs for NIST curves).
"Golden" here means all the values are independent from OpenSSL's ECC
code. I used sage to calculate them. What comes from OpenSSL is:
1. The OIDs (parsed by tooling)
2. The curve parameters (parsing ecparam output with tooling)
The values inside the PEMs (private keys, public keys) and shared keys
are from sage. The PEMs themselves are the output of asn1parse, with
input taken from sage.

Currently if you encounter application data while waiting for a
close_notify from the peer, and you have called SSL_shutdown() then
you will get a -1 return (fatal error) and SSL_ERROR_SYSCALL from
SSL_get_error(). This isn't accurate (it should be SSL_ERROR_SSL) and
isn't persistent (you can call SSL_shutdown() again and it might then work).
We change this into a proper fatal error that is persistent.
