Deprecate Array::capacity() and Sparse::capacity() for numel() and nzmax(). * liboctave/array/Array.h (Array::capacity): deprecate for ::numel(). * liboctave/array/Sparse.h (Sparse::capacity): deprecate for ::nzmax(). Also move comments into doxygen docs. * libinterp/corefcn/daspk.cc, libinterp/corefcn/dasrt.cc, libinterp/corefcn/dassl.cc, libinterp/corefcn/jit-typeinfo.h, libinterp/corefcn/quad.cc, libinterp/corefcn/variables.cc, libinterp/octave-value/ov-base-sparse.h, libinterp/octave-value/ov-base.h, libinterp/octave-value/ov.h, liboctave/array/Sparse.cc, liboctave/numeric/DASPK.cc, liboctave/numeric/DASRT.cc, liboctave/numeric/DASSL.cc, liboctave/numeric/LSODE.cc, liboctave/numeric/Quad.cc, liboctave/numeric/base-de.h, liboctave/numeric/base-min.h, liboctave/numeric/oct-rand.cc: replace use of capacity by numel() or nzmax() as appropriate.
