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.

 * 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

the verify app man page didn't describe the usage of attime option
even though it was listed as a valid option in the -help message.

This patch fixes this omission.

While the -help message references this option, the man page
doesn't mention the -no_ecdhe option.
This patch fixes this omission.

Add an NSS output format to sess_id to export to export the session id and the master key in NSS keylog format. PR#3352

PR#3357

Moved note about lack of support for AEAD modes out of BUGS section to SUPPORTED CIPHERS section (bug has been fixed, but still no support for AEAD)

Specify -f is for compilation flags. Add -d to synopsis section.

Closes #77.

Add option to set an alternative to the default hmacWithSHA1 PRF
for PKCS#8 private key encryptions. This is used automatically
by PKCS8_encrypt if the nid specified is a PRF.

Add option to pkcs8 utility.

Update docs.

apps/pkcs12.c accepts -password as an argument.  The document author
almost certainly meant to write "-password, -passin".

However, that is not correct, either.  Actually the code treats
-password as equivalent to -passin, EXCEPT when -export is also
specified, in which case -password as equivalent to -passout.

change documentation and comments to indicate that we prefer the
standard "DHE" naming scheme everywhere over the older "EDH"

DHE is the standard term used by the RFCs and by other TLS
implementations.  It's useful to have the internal variables use the
standard terminology.

This patch leaves a synonym SSL_kEDH in place, though, so that older
code can still be built against it, since that has been the
traditional API.  SSL_kEDH should probably be deprecated at some
point, though.

Newer pod2man considers =item [1-9] part of a numbered list, while =item
0 starts an unnumbered list. Add a zero effect formatting mark to override
this.

number

PR#3146

Add callbacks supporting generation and retrieval of supplemental data entries, facilitating RFC 5878 (TLS auth extensions)
Removed prior audit proof logic - audit proof support was implemented using the generic TLS extension API
Tests exercising the new supplemental data registration and callback api can be found in ssltest.c.
Implemented changes to s_server and s_client to exercise supplemental data callbacks via the -auth argument, as well as additional flags to exercise supplemental data being sent only during renegotiation.

 * Many XMPP servers are configured with multiple domains (virtual hosts)
 * In order to establish successfully the TLS connection you have to specify
   which virtual host you are trying to connect.
 * Test this, for example with ::
   * Fail:
       openssl s_client -connect talk.google.com:5222 -starttls xmpp
   * Works:
       openssl s_client -connect talk.google.com:5222 -starttls xmpp -xmpphost gmail.com
