C++ conformance. (building with /permissive-) (#7855)

These issues were found when building with the /permissive- flag in the
latest version of MSVC. No tests were added/modified because this does not
change any behavior.
There are a few types of language conformance issues fixed in this:

1) Strict string conversion (this is also covered by the /Zc:strictStrings
flag)

The 'const' is not implicitly dropped by string literals, which means the
following is not allowed:
char str = "const string literal"; //error: cannot convert a 'const char'
to a 'char*'
This fix to to make str 'const char*'. (This can have a domino effect
depending on where str is used)

2) Fully qualified inline declarations members inside class

struct A {
void A::f() { } // Error: illegal qualified name in member declaration,
remove redundant 'A::' to fix
};

3) MSVC by default will allows name lookup in a dependent base. This is
disabled by /permissive-

template <class T> struct B {
  void f();
};

template <class T> struct D
 : public B<T> //B is a dependent base because its type depends on the type of T in D<T>.
{
    //One possible fix is to uncomment the following line.  If this
    //were a type we should have 'using typename'...
    //using B<T>::f;

    void g() {
       f(); //Error: identifier not found, one possible fix is change it to 'this->f();'
    }
};

void h()
{
   D<int> d;
   d.g();
}

4) Warning 4800 has been removed in version 19.1 (1910) of the compiler.

For backwards compatability, surround the usage of 4800.
This is not related to C++ conformance.
 #if _MSC_VER <= 1900
 // 'BOOL' forcing value to bool 'true' or 'false'
 #pragma warning(disable: 4800)
 #endif
