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.
