X509_STORE_add_cert and X509_STORE_add_crl are changed to return
success if the object to be added was already found in the store, rather
than returning an error.

and 1 byte for the signature. In TLSv1.3 each sig alg is represented by
two bytes, where the two bytes together represent a single hash and
signature combination. This converts the internal representation of sigalgs
to use a single int for the pair, rather than a pair of bytes.

A new X509_VERIFY_PARAM_set_auth_level() function sets the
authentication security level.  For verification of SSL peers, this
is automatically set from the SSL security level.  Otherwise, for
now, the authentication security level remains at (effectively) 0
by default.

The new "-auth_level" verify(1) option is available in all the
command-line tools that support the standard verify(1) options.

New verify(1) tests added to check enforcement of chain signature
and public key security levels.  Also added new tests of enforcement
of the verify_depth limit.

Viktor Dukhovni 4fa52141b0 Protocol version selection and negotiation rewrite
The protocol selection code is now consolidated in a few consecutive
short functions in a single file and is table driven.  Protocol-specific
constraints that influence negotiation are moved into the flags
field of the method structure.  The same protocol version constraints
are now applied in all code paths.  It is now much easier to add
new protocol versions without reworking the protocol selection
logic.

In the presence of "holes" in the list of enabled client protocols
we no longer select client protocols below the hole based on a
subset of the constraints and then fail shortly after when it is
found that these don't meet the remaining constraints (suiteb, FIPS,
security level, ...).  Ideally, with the new min/max controls users
will be less likely to create "holes" in the first place.

Matt Caswell e481f9b90b Remove support for OPENSSL_NO_TLSEXT
Given the pervasive nature of TLS extensions it is inadvisable to run
OpenSSL without support for them. It also means that maintaining
the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
not well tested). Therefore it is being removed.

Move per-connection state out of the CERT structure: which should just be

Rich Salz 16f8d4ebf0 memset, memcpy, sizeof consistency fixes
Just as with the OPENSSL_malloc calls, consistently use sizeof(*ptr)
for memset and memcpy.  Remove needless casts for those functions.
For memset, replace alternative forms of zero with 0.

Rich Salz b4faea50c3 Use safer sizeof variant in malloc
For a local variable:
        TYPE *p;
Allocations like this are "risky":
        p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption.  Instead do this:
        p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.
