Use thread-safe atomic reference counting (GCC and MSVC).
* configure.ac: New --enable-atomic-refcount argument.
(octave_allocator): Fix USE_OCTAVE_ALLOCATOR variable assignment.
(OCTAVE_CONFIG_INCLUDED): New macro in config.h.
* oct-refcount.h (OCTREFCOUNT_ATOMIC_INCREMENT,
OCTREFCOUNT_ATOMIC_INCREMENT_POST, OCTREFCOUNT_ATOMIC_DECREMENT,
OCTREFCOUNT_ATOMIC_DECREMENT_POST): New macro, defined for MSVC and GCC
when USE_ATOMIC_REFCOUNT is defined.
(octave_refcount:operator++, octave_refcount::operator--): Use them.
(octave_refcount::operator count_type): Cast returned value to volatile.
(octave_refcount::direct): Remove unsafe member.
* Array.h (Array::make_unique): Delete rep if refcount reaches 0.
* Sparse.h (Sparse::make_unique): Delete rep if refcount reaches 0.
* Array.h (Array:~Array, Array::operator=): Delete rep only when refcount is
excatly 0.
* Array.cc (Array::clear): Likewise.
* Sparse.cc (Sparse::~Sparse, Sparse::operator=): Likewise.
* SparseCmplxQR.h (SparseCmplxQR::~SparseCmplxQR, SparseCmplxQR::operator=):
Likewise.

* sparse-base-chol.h (sparse_base_chol::~sparse_base_chol,
sparse_base_chol::operator): Likewise.
* dim-vector.h (oct-refcount.h): New included header.
(dim_vector::make_unique, dim_vector::resize): Use OCTREFCOUNT_ATOMIC_DECREMENT
macro and delete rep when refcount reaches 0.
(dim_vector::dim_vector): Use OCTREFCOUNT_ATOMIC_INCREMENT.
(dim_vector::operator=): Use OCTREFCOUNT_ATOMIC_INCREMENT and
OCTREFCOUNT_ATOMIC_DECREMENT.
(dim_vector::~dim_vector): Use OCTREFCOUNT_ATOMIC_DECREMENT.
* oct-mutex.h (oct-refcount.h): New included header.
(octave_base_mutex::count): Use octave_refcount class.
* gl-render.cc (oct-refcount.h): New included header.
* graphics.h.in (oct-refcount.h): Likewise.
(base_property::count, base_graphics_toolkit::count,
base_graphics_object::count, base_graphics_event::count): Use octave_refcount.
(property::~property, property::operator=): Delete rep only when refcountn is
excatly 0.
* oct-map.h (octave_fields::make_unique): Delete rep when refcount reaches 0.
* oct-stream.h (oct-refcount.h): New included header.
(octave_base_stream::count): Use octave_refcount class.
* ov.h (octave_value::make_unique): Delete rep when refcount reaches 0.
* symtab.h (oct-refcount.h): New included header.
(symbol_record_rep::count, fcn_info_rep::count): Use octave_refcount class.
