AFAICT, it has been around as long as G_get_null_value_row() has
existed. G_get_null_value_row() returns the raw data, without any
reclass applied.

As it stands, this function probably isn't of much use. If it is to be
retained in its current form, it should have _no_reclass appended to
the name. The existing name should be used for a function which
honours any reclass table (done in 7.0 with r46323).

In 7.0, it's also used by r.neighbors and the OGSF library.
