avoid fixed-size buffers in index exception code
* lo-array-gripes.h, lo-array-gripes.cc (index_exception::expression):
Use std::ostringstream instead of fixed size buffer.
(gripe_invalid_index): Likewise.
(out_of_range::details): Likewise.
(index_exception::index_exception): Set default dim value to -1.
* ov-complex.h, ov-complex.cc (gripe_complex_index): Now static.
Pass arg by const reference instead of value. Use std::ostringstream
instead of fixed size buffer.
(octave_complex::index_vector): Move definition out of header file.
