Trivial fixes for windows compile failures

- Add strmov_overlapp.c where it's needed
- Add libevent where it is required
- Fix typo in unittest/mysys/waiting_threads-t.c
- fix xtradb C language source so that they have variable declarations before
  any operators, as it is (or was?) required in C.
