Summary: Warnings when using std library

Initial Comment:
When using std_vector.i or std_map.i with Python (and probably other languages that have no concept of const), swig generates warnings such as:

/usr/share/swig1.3/std/std_vector.i:93: Warning(512): Overloaded begin() const ignored. Non-const method at /usr/share/swig1.3/std/std_vector.i:93 used.
/usr/share/swig1.3/std/std_vector.i:93: Warning(512): Overloaded end() const ignored. Non-const method at /usr/share/swig1.3/std/std_vector.i:93 used.
/usr/share/swig1.3/std/std_vector.i:93: Warning(512): Overloaded rbegin() const ignored. Non-const method at /usr/share/swig1.3/std/std_vector.i:93 used.
/usr/share/swig1.3/std/std_vector.i:93: Warning(512): Overloaded rend() const ignored. Non-const method at /usr/share/swig1.3/std/std_vector.i:93 used.

This is because Lib/std/std_container.i contains both
    iterator begin();
    iterator end();
    reverse_iterator rbegin();
    reverse_iterator rend();
and
    const_iterator begin() const;
    const_iterator end() const;
    const_reverse_iterator rbegin() const;
    const_reverse_iterator rend() const;

Removing the const versions of begin(), end(), rbegin(), and rend() from Lib/std/std_container.i removes the warnings.

Using std_map.i generates similar warnings about the const versions of find(), lower_bound(), and upper_bound().

For a test case that illustrates the warnings, see #1727629.
