[openssl-dev] [openssl.org #3986] [PATCH] Implement HKDF algorithm (RFC 5869)

[Alessandro Ghedini via RT]

Just FYI, I updated the GitHub pull request [0] with the following:

- Merged patches into a single commit. This just makes more sense, and it's not
  much more complicated to review.
- Added HKDF_Extract() function to the interface. This is basically equivalent
  to calling HMAC(), but the TLS 1.3 draft started using it explicitly so I
  thought it would make the API more complete.
- Added documentation for all the new functions (see doc/crypto/hkdf.pod).
- Updated util/mkdef.pl to parse hkdf.h as well, and updated util/libeay.num.

Now all the builds on Travis CI run fine (except the ones that were already
failing).

Cheers
