We can end up with a NULL SSL_METHOD function if a method has been
disabled. If that happens then we shouldn't call vent->smeth().

Simple tests only need to implement register_tests().
Tests that need a custom main() should implement test_main(). This will
be wrapped in a main() that performs common setup/teardown (currently
crypto-mdebug).
Note that for normal development, enable-asan is usually
sufficient for detecting leaks, and more versatile.
enable-crypto-mdebug is stricter as it will also
insist that all static variables be freed. This is useful for debugging
library init/deinit; however, it also means that test_main() must free
everything it allocates.

Nothing is using this yet, it just adds the underlying functions necesary
for generating the TLS1.3 secrets.

Normally WPACKETs will use a BUF_MEM which can grow as required. Sometimes
though that may be overkill for what is needed - a static buffer may be
sufficient. This adds that capability.

At the moment you can only do an HKDF Extract and Expand in one go. For
TLS1.3 we need to be able to do an Extract first, and the subsequently do
a number of Expand steps on the same PRK.

compression methods correctly, which could lead to uninit reads or crashes.

For consistency, it's better to use the perl that was specified to
Configure last time it was called.
Use case:
perl v5.8.8 was first along $PATH, perl v5.22.2 was available and
specified as: PERL=/opt/local/bin/perl ./config. When make wanted to
reconfigure and called './Configure reconf', configuration broke down,
complaining about a perl that's too old.
