crypto: Refactor nif code to use EVP interface
Using the generic EVP_* API makes it possible to unify algorithm-specific nif functions to a single generic function. Effectively the same change that took place on the Erlang API in R16B01 is now applied to the C code. The old implementation using the low-level API is kept for compiling against old OpenSSL, as parts of the EVP API were introduced in OpenSSL 1.0.0. There are various minor improvements as well: - supported algorithms are now provided by the nif code (not a mix of the C and Erlang code) - remove unnecessary variables and macro definitions Most of the changes in this commit comes from Dániel Szoboszlay https://github.com/dszoboszlay/otp/commit/07f7056f955b324df4ace which is part of his 'fips' branch. Now also rebased on master branch.
