657489e812 cross-reference the DH and RSA SECLEVEL to level of security mappings
Since the DH check is used only in DHE-PSK ciphersuites, it's
easy to miss it when updating the RSA mapping. Add cross-references
so that they remain consistent.

3bcc933ec4 Teach EVP_PKEYs to say whether they were decoded from explicit params
Currently we explicitly downgrade an EVP_PKEY to an EC_KEY and ask
the EC_KEY directly whether it was decoded from explicit parameters or not.
Instead we teach EVP_PKEYs to respond to a new parameter for this purpose.

cdf63a3736 Add X509 version constants.
The X509 version APIs return the numerical values of the version
numbers, which are one off from the names. This is a bit confusing.
Where they don't get it wrong (accidentally making an "X509v4"
certificate), callers tend to try commenting every call site to explain
the mismatch, including in OpenSSL itself.

Define constants for these values, so code can be self-documenting and
callers are nudged towards the right values.

63ae847679 x509_vfy: remove redundant stack allocation
Fix CID 1472833 by removing a codepath that attempts to allocate a
stack if not already allocated, when the stack was already allocated
unconditionally a few lines previously.

Interestingly enough, this additional allocation path (and the comment
describing the need for it) were added in commit
69664d6af0, also prompted by Coverity(!).
It seems that the intervening (and much more recent) commit
d53b437f99 that allowed sk_X509_dup()
to accept a NULL argument allowed the earlier initialization path
to unconditionally allocate a stack, rendering this later allocation fully
redundant.

3bed88a397 x509_vfy.c: Restore rejection of expired trusted (root) certificate
The certificate path validation procedure specified in RFC 5280 does not
include checking the validity period of the trusted (root) certificate.
Still it is common good practice to perform this check.
Also OpenSSL did this until commit 0e7b1383e, which accidentally killed it.

The current commit restores the previous behavior.
It also removes the cause of that bug, namely counter-intuitive design
of the internal function check_issued(), which was complicated by checks
that actually belong to some other internal function, namely find_issuer().

Moreover, this commit adds a regression check and proper documentation of
the root cert validity period check feature, which had been missing so far.

The OPENSSL_CTX type stands out a little by using a different prefix.

02a2567173 Allow to continue on UNABLE_TO_VERIFY_LEAF_SIGNATURE
This unifies the behaviour of a single certificate with
an unknown CA certificate with a self-signed certificate.
The user callback can mask that error to retrieve additional
error information. So the user application can decide to
abort the connection instead to be forced by openssl.

This change in behaviour is backward compatible as user callbacks
who don't want to ignore UNABLE_TO_VERIFY_LEAF_SIGNATURE will
still abort the connection by default.
