Check we send supported_groups in EE if there is a group we prefer instead
of the one sent in the key_share.

The TLSv1.3 spec says that a server SHOULD send supported_groups in the
EE message if there is a group that it prefers to the one used in the
key_share. Clients MAY act on that. At the moment we don't do anything
with it on the client side, but that may change in the future.

The conditions to skip these recipes entirely don't show in a
non-verbose test harness output.  We prefer to know, so use skip_all,
as it is a little bit more verbose.

Perl, multiple versions, for some reason occasionally takes issue with

0xb1 came out wrong when generating code for MASM. Fixes GH#3241.

Format the test failure output more nicely.

More vertical space is used to make things a little clearer.  Tests are expected
to pass so this doesn't impact the normal case.

Strings and memory comparisons highlight differences.

The previous commit fixed a bug which occurs when serverinfo is loaded
from memory (not from a file). This adds a test for loading serverinfo

SSL_CTX_use_serverinfo_ex() et al were always processing data as if it was
V2 format, even if it was V1. This bug was masked because, although we had
a test which loaded V1 serverinfo data from a file, the function
SSL_CTX_use_serverinfo_file() transparently converts V1 data to V2 before
calling SSL_CTX_use_serverinfo_ex().

The init code uses DSO_dsobyaddr() to leak a reference to ourselves to
ensure we remain loaded until atexit() time. In some circumstances that
