71c8cd2085 Make it possible to generate proxy certs with test/certs/mkcert.sh
This extends 'req' to take more than one DN component, and to take
them as full DN components and not just CN values.  All other commands
are changed to pass "CN = $cn" instead of just a CN value.

This adds 'genpc', which differs from the other 'gen*' commands by not
calling 'req', and expect the result from 'req' to come through stdin.

Finally, test/certs/setup.sh gets the commands needed to generate a
few proxy certificates.

fbb82a60dc Move peer chain security checks into x509_vfy.c
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.

Updated documentation.

4d9e33acb2 Require intermediate CAs to have basicConstraints CA:true.
Previously, it was sufficient to have certSign in keyUsage when the
basicConstraints extension was missing.  That is still accepted in
a trust anchor, but is no longer accepted in an intermediate CA.

c0a445a9f2 Suppress DANE TLSA reflection when verification fails
As documented both SSL_get0_dane_authority() and SSL_get0_dane_tlsa()
are expected to return a negative match depth and nothing else when
verification fails.  However, this only happened when verification
failed during chain construction.  Errors in verification of the
constructed chain did not have the intended effect on these functions.

This commit updates the functions to check for verify_result ==
X509_V_OK, and no longer erases any accumulated match information
when chain construction fails.  Sophisticated developers can, with
care, use SSL_set_verify_result(ssl, X509_V_OK) to "peek" at TLSA
info even when verification fail.  They must of course first check
and save the real error, and restore the original error as quickly
as possible.  Hiding by default seems to be the safer interface.

Introduced X509_V_ERR_DANE_NO_MATCH code to signal failure to find
matching TLSA records.  Previously reported via X509_V_ERR_CERT_UNTRUSTED.

This also changes the "-brief" output from s_client to include
verification results and TLSA match information.

Mentioned session resumption in code example in SSL_CTX_dane_enable(3).
Also mentioned that depths returned are relative to the verified chain
which is now available via SSL_get0_verified_chain(3).

Added a few more test-cases to danetest, that exercise the new
code.

Resolved thread safety issue in use of static buffer in
X509_verify_cert_error_string().

Fixed long-stating issue in apps/s_cb.c which always sets verify_error
to either X509_V_OK or "chain to long", code elsewhere (e.g.
s_time.c), seems to expect the actual error.  [ The new chain
construction code is expected to correctly generate "chain
too long" errors, so at some point we need to drop the
work-arounds, once SSL_set_verify_depth() is also fixed to
propagate the depth to X509_STORE_CTX reliably. ]

33cc5dde47 Compat self-signed trust with reject-only aux data
When auxiliary data contains only reject entries, continue to trust
self-signed objects just as when no auxiliary data is present.

This makes it possible to reject specific uses without changing
what's accepted (and thus overring the underlying EKU).

Added new supported certs and doubled test count from 38 to 76.

3d6e91c680 Commit pre-generated test_verify certs
These can be re-generated via:

        cd test/certs; ./setup.sh

if need be.  The keys are all RSA 2048-bit keys, but it is possible
to change that via environment variables.

    cd test/certs
    rm -f *-key.pem *-key2.pem
    OPENSSL_KEYALG=rsa OPENSSL_KEYBITS=3072 ./setup.sh

    cd test/certs
    rm -f *-key.pem *-key2.pem
    OPENSSL_KEYALG=ecdsa OPENSSL_KEYBITS=secp384r1 ./setup.sh

    ...

Keys are re-used if already present, so the environment variables
are only used when generating any keys that are missing.  Hence
the "rm -f"
