This commit adds the general verify options of ocsp, verify,
cms, etc. to the openssl timestamping app as suggested by
Stephen N. Henson in [openssl.org #4287]. The conflicting
"-policy" option of "openssl ts" has been renamed to
"-tspolicy". Documentation and tests have been updated.

CAVE: This will break code, which currently uses the "-policy"
option.

The ocsp utility is something of a jack-of-all-trades; most anything
related to the OCSP can be done with it.  In particular, the manual
page calls out that it can be used as either a client or a server
of the protocol, but there are also a few things that it can do
which do not quite fit into either role, such as encoding an OCSP
request but not sending it, printing out a text form of an OCSP
response (or request) from a file akin to the asn1parse utility,
or performing a lookup into the server-side revocation database
without actually sending a request or response.  All three of these
are documented as examples in the manual page, but the documentation
prior to this commit is somewhat misleading, in that when printing
the text form of an OCSP response, the code also attempts to
verify the response, displaying an error message and returning
failure if the response does not verify.  (It is possible that
the response would be able to verify with the given example, since
the default trust roots are used for that verification, but OCSP
responses frequently have alternate certification authorities
that would require passing -CAfile or -CApath for verification.)

Tidy up the documentation by passing -noverify for the case of
converting from binary to textual representation, and also
change a few instances of -respin to -reqin as appropriate, note
that the -url option provides the same functionality as the -host
and -path options, clarify that the example that saves an OCSP
response to a file will also perform verification on that response,
and fix a couple grammar nits in the manual page.

Also remove an always-true conditional for rdb != NULL -- there
are no codepaths in which it could be initialized at the time of
this check.

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. ]

It is sometimes useful (especially in automated tests) to supply
multiple trusted or untrusted certificates via separate files rather
than have to prepare a single file containing them all.

To that end, change verify(1) to accept these options zero or more
times.  Also automatically set -no-CAfile and -no-CApath when
-trusted is specified.
