Sebastian Dröge 2ba5105b80 Implement Sync/Send for more types and don't implement Send for TypeFind
They can actually be shared with multiple threads at the same time
safely as all functions requiring an immutable reference are
thread-safe.

OTOH TypeFind can't be shared safely between different threads as not
all implementations of the TypeFind struct are thread-safe.
