is_streamable is a meta-function that checks if a type is streamable
is_streamable<T>::value is true iff the type T has stream operators <<
and >>. Otherwise it is false.
That commit adds a new header, used nowhere, and a new test. That cannot
break anything. I do it directly to 'next', with my own approval.
Identity_iterator was neither documented nor used anywhere throughout
the code base and served no real purpose and can easier be implemented
(if really needed) with iterator_adaptor or the iterator helpers in
boost operators.

| When CGAL_NO_ASSERTIONS, fix CGAL_static_assertion

| CGAL_static_assertion cannot be "static_cast<void>(0)" because that
| macro can also be used in a class or namespace scope.

| Avoid a warning with -ansi -pedantic when CGAL_NO_ASSERTIONS
|
| When CGAL_NO_ASSERTIONS is defined (when NDEBUG is defined, for example),
| "CGAL_static_assertion(true);" must not be expanded to ";", to avoid a
| pedantic warning "extra ;".

That was just a very wrong way to fix a pedantic warning: the new
implementations were buggy.
When CGAL_NO_ASSERTIONS is defined (when NDEBUG is defined, for example),
"CGAL_static_assertion(true);" must not be expanded to ";", to avoid a
pedantic warning "extra ;".
