crypto: New experimental api

The new files api_ng.h and api_ng.c implements an api using EVP.
The api is not by any mean new, except for the crypto application
in Erlang/OTP.

The aims at using the block api in a stream manor, that is
  1) call crypto_init/4
  2..N) call crypto_update/{2,3}

The purpose is to simplify and hopefully optimize the SSL and SSH
applications.

By keeping the crypto state in C in an enif_resource the costful state
copying in SSL and SSH is reduced with 1-2 per message sent or received.

Changes in other files are for adaptation like FIPS etc since many
functions uses the central get_cipher_type() function.
