Trace APIs

Debug tracing functions that write a label and a value (a buffer, a signed integer, or an XFL float) to the server's trace log. They are purely diagnostic and have no effect on transaction outcome. These functions used to share the "Utility APIs" page; for the return-value and error-code conventions they follow, see Utility APIs.
