Christopher Haster 161a2ec259 callback - Added size-limited function-object overloads to Callback 
The callback class can now accept generalized function-objects:

    class Thing {
    public:
        int value;

        void operator()() {
            printf("hi! %d\n", value);
        }
    };

    Callback<void()> cb(Thing(2));

However, with the intention of avoiding implicit dynamic-memory
allocations, the Callback class is limited to a single word of storage.
Exceeding this size will eliminate the function-object type from the
overload set and fail to compile.

Effort was invested to make this situation very clear to the user. Here
is an example error message with noise removed:

    [ERROR] ./main.cpp: In function 'int main()':
    ./mbed-os/hal/api/Ticker.h:101:10: note:
        no known conversion for argument 1 from 'BigFunc' to 'mbed::Callback<void()>'

The real benefit of this change is the ability for users to hook into
the attributes of the Callback class. This mostly allows lifetime
management of the function-objects from third-party libraries (such as
the Event class from mbed-events).

Note: The convenient `callback` function may become ambiguous if
provided with a type that defines multiple incompatible `operator()`
member functions.
