Remove openssl dynlock functions
OpenSSL lets you provide hooks so that locks can be dynamically allocated. But it doesn't actually use those hooks: They don't appear in our unit test coverage, and the openssl manual even says: ``` Also, dynamic locks are currently not used internally by OpenSSL, but may do so in the future. ``` I propose that we disable this code. I'll do it as part of my legacy/trac#16794 branch.
