Document use of -keyopt to use RSA-PSS and RSA-OAEP modes.

Add new tests to cms-test.pl covering PSS and OAEP.

Add support for custom public key parameters in the cms utility using
the -keyopt switch. Works for -sign and also -encrypt if -recip is used.

Extend RSA ASN1 method to support CMS PSS signatures for both sign
and verify.

For signing the EVP_PKEY_CTX parameters are read and the appropriate
CMS structures set up.

For verification the CMS structures are analysed and the corresponding
parameters in the EVP_PKEY_CTX set.

Also add RSA-OAEP support.

For encrypt the EVP_PKEY_CTX parameters are used.

For decrypt the CMS structure is uses to set the appropriate EVP_PKEY_CTX
parameters.

Add support for customisation of CMS handling of signed and enveloped
data from custom public key parameters.

This will provide support for RSA-PSS and RSA-OAEP but could also be
applied to other algorithms.

Add OAEP ctrls to retrieve MD and label. Return errors if
an attempt is made to set or retrieve OAEP parameters when
padding mode is not OAEP.

serverinfo rejects non-empty extensions.

Omit extension if no relevant serverinfo data.

Improve error-handling in serverinfo callback.

Cosmetic cleanups.

s_client documentation.

s_server documentation.

SSL_CTX_serverinfo documentation.

Cleaup -1 and NULL callback handling for custom extensions, add tests.

Cleanup ssl_rsa.c serverinfo code.

Whitespace cleanup.

Improve comments in ssl.h for serverinfo.

Whitespace.

Cosmetic cleanup.

Reject non-zero-len serverinfo extensions.

Make it build.

Improve RSA sing performance by 20-30% by:
- switching from floating-point to integer conditional moves;
- daisy-chaining sqr-sqr-sqr-sqr-sqr-mul sequences;
- using MONTMUL even during powers table setup;

This change adds the option to calculate (EC)DSA nonces by hashing the
message and private key along with entropy to avoid leaking the private
key if the PRNG fails.

in order to prevent ssl3_get_record from never returning.

Reported by "oftc_must_be_destroyed" and George Kadianakis.

that bad encryptions are treated like random session keys in constant
time.

PR#3071

The primary changes made are:
- Updates to the "NAME" section of many pages to correctly reflect the
functions defined on those pages. This section is automatically parsed
by the util/extract-names.pl script, so if it is not correct then
running "man" will not correctly locate the right manual pages.
- Updates to take account of where functions are now deprecated
- Full documentation of the ec sub-library
- A number of other typo corrections and other minor tweaks

Extend OAEP support. Generalise the OAEP padding functions to support
arbitrary digests. Extend EVP_PKEY RSA method to handle the new OAEP
padding functions and add ctrls to set the additional parameters.

Fix PSS signature printing: consistently use 0x prefix for hex values for
padding length and trailer fields.
