[PATCH] native inline gravatar

[Jason A. Donenfeld]

Sorry, but not a chance something like this can be accepted. This is
exactly the reason we put the time into making the Lua scripting
support. Is your reason for implementing this C performance? In that
case, could you send some performance metrics and some details about
your performance requirements on a given system? Considering the Lua
crypto module links against OpenSSL, I'm pretty sure that its hashing
performance will be considerably better the slow reference
implementation in this patch [1].
