 * Output a TTL or other time interval in a human-readable form.
 * The time interval is given as a count of seconds in 'src'.
 * The text representation is appended to 'target'.
 *
 * If 'verbose' is false, use the terse BIND 8 style, like "1w2d3h4m5s".
 *
 * If 'verbose' is true, use a verbose style like the SOA comments
 * in "dig", like "1 week 2 days 3 hours 4 minutes 5 seconds".
 *
 * If 'upcase' is true, we conform to the BIND 8 style in which
 * the unit letter is capitalized if there is only a single unit
 * letter to print (for example, "1m30s", but "2M")
 *
 * If 'upcase' is false, unit letters are always in lower case.
