Haskell bindings to the fastpbkdf2 C library

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

Haskell bindings to the fastpbkdf2 library. This is currently (Dec 2016) the fastest Haskell library for computing the pbkdf2, outperforming competitors by several order of magnitude (unsuprisingly, as it hooks into some C code!):

benchmarking sha1/fastpbkdf2
time                 4.948 ms   (4.850 ms .. 5.040 ms)

This library depends from OpenSSL. I have tried to make this self-contained, but the crypto layer of OpenSSL (or BoringSSL) requires some fine-tuned ASM code generated during the build process. Porting everything over in a customised Build.hs would have been too much pain, but PR are super welcome!
