Fix test_ssl_new test failure

A couple of fetches of the MD5 and SHA1 digests were not using the
libctx in libssl and causing test_ssl_new to fail in travis. This
only occurs on builds with SSLv3 enabled (its disabled by default).

Fix NULL dereference in SSL_check_chain() for TLS 1.3

In the tls1_check_sig_alg() helper function, we loop through the list of
"signature_algorithms_cert" values received from the client and attempt
to look up each one in turn in our internal table that maps wire
codepoint to string-form name, digest and/or signature NID, etc., in
order to compare the signature scheme from the peer's list against what
is used to sign the certificates in the certificate chain we're
checking.  Unfortunately, when the peer sends a value that we don't
support, the lookup returns NULL, but we unconditionally dereference the
lookup result for the comparison, leading to an application crash
triggerable by an unauthenticated client.

Since we will not be able to say anything about algorithms we don't
recognize, treat NULL return from lookup as "does not match".

We currently only apply the "signature_algorithm_cert" checks on TLS 1.3
connections, so previous TLS versions are unaffected.  SSL_check_chain()
is not called directly from libssl, but may be used by the application
inside a callback (e.g., client_hello or cert callback) to verify that a
candidate certificate chain will be acceptable to the client.

Add test for CVE-2020-1967

Add to test_sslsigalgs a TLSProxy test that injects a
"signature_algorithms_cert" extension that contains an unallocated
codepoint.

The test currently fails, since s_server segfaults instead of
ignoring the unrecognized value.

Since "signature_algorithms" and "signature_algorithms_cert" are very
similar, also add the analogous test for "signature_algorithms".

Developer scripts: Release script

The old release script that exists in another repository has aged, and
risks becoming messy beyond maintainability if it's made to deal with
multiple OpenSSL version schemes.

A solution, which has been seen in other projects, is to have the
release script as part of the versioned source tree, and ensure it's
adapted for the ongoing version scheme in that source tree.

This introduces dev/, a directory of OpenSSL developer "stuff".  We
may expand it with other practical scripts to easy development setup
and other similar things that developers may need.  For now, it's the
release script dev/release.sh, with auxilliary files in dev/release-aux/.
The script is self describing, the manual is available by running the
command `./dev/release.sh --manual`.

The dev/ directory shall never appear in a source distribution.

EVP: Add a temporary SM2 hack to key generation

mkerr: remove legacy guards from generated error headers

In pull request #9333, legacy guards were added to the generated
error headers, but the mkerr.pl script was not adjusted accordingly.
So the legacy guards were removed by subsequent `make update` calls.

Fixing the mkerr.pl script properly was disproportionately complicated
by the fact that adding legacy guards only made sense for files which
already existed in version 1.1.1. To keep things simple, it was decided
to drop the legacy guards from the generated headers entirely.
