fix #1305

Applies to:

    flat_buffer
    flat_static_buffer
    multi_buffer
    static_buffer

Changes:

* Revised all javadocs
* Move construction does not invalidate in some cases
* non-const data() returns a mutable buffer sequence
* Add cdata() to also return constant readable bytes
* Eligible member functions are declared noexcept
