"using namespace" is inside of mbed.h

[Alex-EEE]

Description

mbed.h has "using namespace std" and "using namespace mbed" . Just spent a bunch of time debugging something b/c I had no idea my namespace had gotten clobbered. Putting using declarations in a header file is forbidden in almost every text written about C++ style:

This is especially bad considering that you need to include "mbed.h" almost everywhere

You guys should refactor this out.

Or a simpler way out would be to deprecate "mbed.h", and make a "new_mbed.h" that has all the #includes, and mbed.h could look like this, for backwards compatibility:

#include "new_mbed.h"
using namespace mbed;
using namespace std;
