In the ssl_cipher_get_evp() function, fix off-by-one errors in index validation before accessing arrays.

Bug discovered and fixed by Miod Vallat from the OpenBSD team.

Incorrect attribution

cms, ocsp, s_client, s_server and smime tools also use args_verify()
for parsing options, that makes them most of the same options
verify tool does. Add those options to man pages and reference
their explanation in the verify man page.

just making sure the options are listed in the alphabetical order
both in SYNOPSIS and DESCRIPTION, no text changes

The options related to policy used for verification, verification
of subject names in certificate and certificate chain handling
were missing in the verify(1) man page. This fixes this issue.

-CAfile and -CApath is documented in OPTIONS but is missing
in SYNOPSIS, add them there

Add -trusted_first description to help messages and man pages
of tools that deal with certificate verification.

Allow CCS after finished has been sent by client: at this point
keys have been correctly set up so it is OK to accept CCS from
server. Without this renegotiation can sometimes fail.

Based on an original patch by Joel Sing (OpenBSD) who also originally identified the issue.

This reverts commit 2f1dffa8.

Missing attribution.

A client reference identity of ".example.com" matches a server
certificate presented identity that is any sub-domain of "example.com"
(e.g. "www.sub.example.com).

With the X509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS flag, it matches
only direct child sub-domains (e.g. "www.sub.example.com").

Fix SEH and stack handling in Win64 build.

(cherry picked from commit 5f4c5a902b0508eab235adecb34b236cdc0048a5)

 * Make a clear distinction between DH and ECDH key exchange.
 * Group all key exchange cipher suite identifiers, first DH then ECDH
 * add descriptions for all supported *DH* identifiers
 * add ECDSA authentication descriptions
 * add example showing how to disable all suites that offer no
   authentication or encryption

Defines SETUP_TEST_FIXTURE and EXECUTE_TEST, and updates ssl/heartbeat_test.c
using these macros. SETUP_TEST_FIXTURE makes use of the new TEST_CASE_NAME
macro, defined to use __func__ or __FUNCTION__ on platforms that support those
symbols, or to use the file name and line number otherwise. This should fix
several reported build problems related to lack of C99 support.
