[openssl-dev] use SIPhash for OPENSSL_LH_strhash?

[Salz, Rich]

> Understood.  Can you further clarify whether you would like to maintain the existing 20-year-old hand-rolled hash function for that purpose or are open to using a more modern hash (not necessarily SIPhash; there are also things like the Jenkins hash to consider)?

Because it works, because nobody has looked at our touched that code, because there are no security concerns and it's unclear if the speed gain(s) make a difference.
