songvec: lock traversals for thread-safe updates/reads
Only one lock is used for all songvec traversals since they're rarely changed. Also, minimize lock time and release it before calling iterator functions since they may block (updateSongInfo => stat/open/seek/read). This lock only protects songvecs (and all of them) during traversals; not the individual song structures themselves.
