Only targets setup by the special LLVM libc rules now have fully
qualified names. The naming style is similar to fully qualified names in
Python.

Summary:
Made all header files consistent based of this documentation: https://llvm.org/docs/CodingStandards.html#file-headers.
And did the same for all source files top of file comments.

The preprocessor reads the whole line even if the first condition of an and is false so this broke when compiling on older gcc versions which don't recognize `__has_builtin`
Summary:
The patch is not ready yet and is here to discuss a few options:
- How do we customize the implementation? (i.e. how to define `kRepMovsBSize`),
- How do we specify custom compilation flags? (We'd need `-fno-builtin-memcpy` to be passed in),
- How do we build? We may want to test in debug but build the libc with `-march=native` for instance,
- Clang has a brand new builtin `__builtin_memcpy_inline` which makes the implementation easy and efficient, but:
- If we compile with `gcc` or `msvc` we can't use it, resorting on less efficient code generation,
- With gcc we can use `__builtin_memcpy` but then we'd need a postprocess step to check that the final assembly do not contain call to `memcpy` (unlikely but allowed),
- For msvc we'd need to resort on the compiler optimization passes.

Header files included wrongly using <...> are now included using the
internal path names as the new unittest framework allows us to do so.
Reviewers: phosek, abrachet
Differential Revision: https://reviews.llvm.org/D72743
Summary:
Now that tests live in separate top-level directory, keeping the
implementations of individual functions in a directory of their own is
not meaningful. Hence, this change moves them into the higher level
string directory.
NFC intended.

Summary:
This patch illustrates some of the features like modularity we want
in the new libc. Few other ideas like different kinds of testing, redirectors
etc are not yet present.
