To make sure that our symbols don't clash with other libraries, we
claim the namespaces OSSL and OPENSSL. Because C doesn't provide
namespaces, the only solution is to have them as prefixes on symbols,
thus we allow OSSL_ and OPENSSL_ as prefixes.
These namespace prefixes are optional for the foreseeable future, and
will only be used for new modules as needed on a case by case basis,
until further notice.
For extra safety, there's an added requirement that module names -
apart from the namespace prefix - be at least 2 characters long.

In draft-ietf-tls-tls13-20 Appendix B we find that:
This section describes protocol types and constants. Values listed
as _RESERVED were used in previous versions of TLS and are listed
here for completeness. TLS 1.3 implementations MUST NOT send them
but might receive them from older TLS implementations.
Similarly, in section 4.2.3 we see:
Legacy algorithms Indicates algorithms which are being deprecated
because they use algorithms with known weaknesses, specifically
SHA-1 which is used in this context with either with RSA using
RSASSA-PKCS1-v1_5 or ECDSA. These values refer solely to
signatures which appear in certificates (see Section 4.4.2.2) and
are not defined for use in signed TLS handshake messages.
Endpoints SHOULD NOT negotiate these algorithms but are permitted
to do so solely for backward compatibility. Clients offering
these values MUST list them as the lowest priority (listed after
all other algorithms in SignatureSchemeList). TLS 1.3 servers
MUST NOT offer a SHA-1 signed certificate unless no valid
certificate chain can be produced without it (see
Section 4.4.2.2).
However, we are currently sending the SHA2-based DSA signature schemes
and many SHA1-based schemes, which is in contradiction with the specification.
Because TLS 1.3 support will appear in OpenSSL 1.1, we are bound by
stability requirements to continue to offer the DSA signature schemes
and the deprecated hash algorithms. at least until OpenSSL 1.2.
However, for pure TLS 1.3 clients that do not offer lower TLS versions,
we can be compliant. Do so, and leave a note to revisit the issue when
we are permitted to break with sacred historical tradition.

Following on from the previous commit this fixes another instance where

Prior to 72ceb6a we treated all failures from the call to
EVP_DigestVerifyFinal() as if it were a bad signature, and failures in
EVP_DigestUpdate() as an internal error. After that commit we replaced
this with the one-shot function EVP_DigestVerify() and treated a 0 return
as a bad signature and a negative return as an internal error. However,
some signature errors can be negative (e.g. according to the docs if the
form of the signature is wrong). Therefore we should treat all <=0
returns as a bad signature.
This fixes a boringssl test failure.

In 1.0.2 and before OBJ_create() allowed the sn or ln parameter to be NULL.
Commit 52832e47 changed that so that it crashed if they were NULL.
This was causing problems with the built-in config oid module. If a long
name was provided OBJ_create() is initially called with a NULL ln and
therefore causes a crash.

BIO_CTRL_DGRAM_SCTP_SET_IN_HANDSHAKE. In an SCTP enabled build
BIO_CTRL_DGRAM_SCTP_SET_IN_HANDSHAKE was used unconditionally with
the reasoning that it would be ignored if SCTP wasn't in use. Unfortunately
due to this clash, this wasn't the case. The BIO ended up going into peek
mode and was continually reading the same data over and over - throwing it
