Updates the minimal libc headers for differences between the C and C++
languages. This includes ...
1. Conditionally defining "bool", "true" and "false" as they are
already keywords in C++.
2. Making the definition of NULL language dependent.
3. Using the _Restrict macro instead of the restrict keyword as
restrict exists in C, but not in C++.
4. Changing the definition of size_t so that it is compatible with
what the compiler expects when building the new operator stubs
(as it varies by architecture).
