SSL: add TLS PSK (RFC 4279 and RFC 5487) cipher suites
CRYPTO: add support for RFC-2945 SRP-3 and RFC-5054 SRP-6a authentication
SSL: add TLS-SRP (RFC 5054) cipher suites
SSL: add tests for PSK and SRP ciphers
SSL: enable hash_size values for sha224, sha384 and sha512

Some of the PSK and SRP ciphers default to sha384, this enables
hash_size for that cipher. It also adds sha512 and sha224 to be
prepared for further cipher enhancements.
SSL: add documentation for PSK and SRP ciphers options
CRYPTO: add algorithms/0 function that returns a list off compiled in crypto algorithms

add algorithms/0 function that returns a list off compiled in crypto algorithms
and make tests suites with SHA226, SHA256, SHA384 and SHA512 conditional based
on that
SSL: replace sha256_mac() tests with crypto:algorithms()
CRYPTO: add support for Elliptic Curves to crypto app
PUBLIC_KEY: add support for Elliptic Curves to public_key app
SSL: filter TLS cipher suites for supported algorithms
SSL: add Elliptic Curve support for ssl app
SSL: add Elliptic Curve ciphers unit tests
