Hello,

I am using curl in a multi-threaded context. According to the
documentation, curl is supposed to be completely thread-safe. However,
ThreadSanitizer warns me about the connection_id_counter variable in the
ConnectionStore() method; and indeed, local statics and threads don't go
well together.

I can fix it and make a pull request on github. My question is, what is the
preferred thread safety mechanism with curl? A quick search doesn't turn up
much in the way of mutexes or atomics in the current code. Any suggestions?
