Add an interface that allows accessing the scrypt KDF as a PKEY_METHOD.
This fixes #4021 (at least for the scrypt portion of the issue).

This implementation is written in endian agnostic C code. No attempt
at providing machine specific assembly code has been made. This
implementation expands the evptests by including the test cases from
RFC 5794 and ARIA official site rather than providing an individual
test case. Support for ARIA has been integrated into the command line
applications, but not TLS. Implemented modes are CBC, CFB1, CFB8,
CFB128, CTR, ECB and OFB128.

The core SipHash supports either 8 or 16-byte output and a configurable
number of rounds.
The default behavior, as added to EVP, is to use 16-byte output and
2,4 rounds, which matches the behavior of most implementations.
There is an EVP_PKEY_CTRL that can control the output size.

The recent merge of https://github.com/openssl/openssl/pull/1264
removed some trailing whitespace from the generated file obj_dat.h.
Unfortunately obj_dat.pl kept re-adding it.  Clean up the
script and the output it generates.
