Deprecate Array::nelem() and Range::nelem() in favour of ::numel().
* liboctave/array/Array.h (Array::nelem) deprecate in favour of numel().
(Array::capacity, Array:: length): change to call numel() directly. These
methods will be deprecated soon.
* liboctave/array/PermMatrix.h (PermMatrix::nelem): deprecate in favour of
numel().
* liboctave/array/Range.h (Range::numel) new method to replace nelem().
(Range::nelem) deprecate in favour of the new method numel.
* liboctave/array/Sparse.h (Sparse::nelem) deprecate in favour of nzmax().
This one is secially bad because unlike the other classes, it is different
from numel().
* libinterp/corefcn/debug.cc, libinterp/corefcn/jit-typeinfo.cc,
libinterp/corefcn/ls-mat4.cc, libinterp/corefcn/lu.cc,
libinterp/corefcn/luinc.cc, libinterp/corefcn/max.cc,
