/**
 * Returns the last code point such that all those from start to there have the same value.
 * Can be used to efficiently iterate over all same-value ranges in a map.
 * (This is normally faster than iterating over code points and get()ting each value,
 * but much slower than a data structure that stores ranges directly.)
 *
 * If the UCPMapValueFilter function pointer is not NULL, then
 * the value to be delivered is passed through that function, and the return value is the end
 * of the range where all values are modified to the same actual value.
 * The value is unchanged if that function pointer is NULL.
 *
 * Example:
 * \code
 * UChar32 start = 0, end;
 * uint32_t value;
 * while ((end = ucpmap_getRange(map, start, UCPMAP_RANGE_NORMAL, 0,
 *                               NULL, NULL, &value)) >= 0) {
 *     // Work with the range start..end and its value.
 *     start = end + 1;
 * }
 * \endcode
 *
 * @param map the map
 * @param start range start
 * @param option defines whether surrogates are treated normally,
 *               or as having the surrogateValue; usually UCPMAP_RANGE_NORMAL
 * @param surrogateValue value for surrogates; ignored if option==UCPMAP_RANGE_NORMAL
 * @param filter a pointer to a function that may modify the map data value,
 *     or NULL if the values from the map are to be used unmodified
 * @param context an opaque pointer that is passed on to the filter function
 * @param pValue if not NULL, receives the value that every code point start..end has;
 *     may have been modified by filter(context, map value)
 *     if that function pointer is not NULL
 * @return the range end code point, or -1 if start is not a valid code point
