avoid mulitple definitions of static function-scope vars (bug #47372) Some systems (Windows, others?) may generate multiple definitions of function-scope static variables if those functions appear in header files. This can cause trouble in various ways. Attempt to avoid the problem by moving functions that contain file-scope varaibles from header files to source files, or by using class-scope static variables instead. Also attempt to avoid similar problems caused by implicit instantiations of templates that have functions with static variables. * Cell.h, Cell.cc (Cell::resize_fill_value): Move definition from header to source file. * oct-map.h, oct-map.cc (octave_fields::nil_rep): Likewise. * ov-base-scalar.h, ov-base-scalar.cc (octave_base_scalar<ST>::dims): Likewise. * ov-fcn-handle.h, ov-fcn-handle.cc (octave_fcn_handle::dims): Likewise. * ov.h, ov.cc (octave_value::nil_rep): Likewise. * Array.h, Array.cc (Array<T>::nil_rep): Likewise. * DiagArray2.h, DiagArray2.cc (DiagArray2<T>::elem, DiagArray2<T>::checkelem): Likewise. * Sparse.h, Sparse.cc (Sparse<T>::nil_rep): Likewise. * dim-vector.h, dim-vector.cc (dim_vector::nil_rep): Likewise. * idx-vector.h, idx-vector.cc (idx_vector::nil_rep, idx_vector::err_rep): Likewise. * oct-inttypes.h, oct-inttypes.cc (octave_int_base<T>::convert_real): Likewise. * symtab.h, symtab.cc (octave_value symbol_table::dummy_octave_value, symbol_table::symbol_record symbol_table::dummy_symbol_record): New class-scope static variables. Use them to eliminate function-scope static variables. * ov-int8.cc, ov-int16.cc, ov-int32.cc, ov-int64.cc, ov-uint8.cc, ov-uint16.cc, ov-uint32.cc, ov-uint64.cc, ov-scalar.cc, ov-flt-complex.cc, ov-complex.cc, ov-classdef.cc, ov-bool.cc, Array-jit.cc, Array-os.cc, Array-tc.cc, Array-C.cc, Array-b.cc, Array-ch.cc, Array-d.cc, Array-f.cc, Array-fC.cc, Array-i.cc, Array-idx-vec.cc, Array-s.cc, Array-str.cc, Array-voidp.cc: Prevent impliticit template instantiation. * Array-tc.cc: Also instantiate Array<cdef_object>.
