@brief Find a set of GPIO lines by names among lines exposed by this chip.
@param chip The GPIO chip object.
@param names Array of pointers to C-strings containing the names of the
lines to lookup. Must end with a NULL-pointer.
@param bulk Line bulk object in which the located lines will be stored.
@return 0 if all lines were located, -1 on error.
@note If at least one line from the list could not be found among the lines
exposed by this chip, the function sets errno to ENOENT.
