c0e9dcff21 revise static_shared_vector_cast 
Move the work into a special ctor
to allow full inline of casting wrapper

Prevent static_shared_vector_cast from
casting const <-> non-const

74f68c47d3 shared_vector_convert 
Allow converting of shared_vector between types

Conversion utilizes castUnsafe<TO,FROM>().

Converting to/from void is supported.  Convert to void
is an alias for static_shared_vector_cast<void>().
Convert from void utilizes shared_vector<void>::original_type()
and throws std::runtime_error if this is not valid.

Casting now handles 'const void'
is most places where 'void' can be used.

4e749cc8be Improve shared_vector::push_back

in powers of 2 up to 1k elements, then
in blocks of 1k elements.

a4cfab1242 Fix "optimize shared_vector for storing non-POD types" 
Can't move references when the source array is
still referenced by other shared_vectors

be4738f59c remove weak_vector 
It seems that shared_ptr::use_count() does
not include weak_ptr instances.  Therefore
shared_ptr::use_count()==1 (aka unique())
does *not* ensure exclusive ownership!

This breaks the assumption used by
shared_vector::make_unique() to avoid
allocating a new array in some cases.

bc3187a3f6 optimize shared_vector for storing non-POD types 
pass values by reference where appropriate.
When reallocating arrays of shared_ptr
"move" with swap() instead of operator=
to avoid ref counter inc and dec for each
element.

3cd2bfdef0 shared_vector implementation 
Shared ownership of a single C array.

Tracks offset and length for each instance
allowing each owner to "view" a different
piece of the array.

Parts of shared_vector<T> which can work
for T=void are in shared_vector_base<T>.
Specializations shared_vector<void>
and shared_vector<const void> handle
un-typed arrays.

Allow casting to/from typed vector

Offsets and sizes of untyped vectors are tracked in
bytes.  Therefore casting to types where sizeof(T)>1
is undefined if the offset is not a multiple of
sizeof(T).
