std: Create separate docs for the primitives

Having the primitive and module docs derived from the same source
causes problems, primarily that they can't contain hyperlinks
cross-referencing each other.

This crates dedicated private modules in `std` to document the
primitive types, then for all primitives that have a corresponding
module, puts hyperlinks in moth the primitive docs and the module docs
cross-linking each other.

This should help clear up confusion when readers find themselves on
the wrong page.

 //! Unicode string slices
 //!
-//! Rust's `str` type is one of the core primitive types of the language. `&str`
-//! is the borrowed string type. This type of string can only be created from
-//! other strings, unless it is a `&'static str` (see below). It is not possible
-//! to move out of borrowed strings because they are owned elsewhere.
-//!
-//! # Examples
-//!
-//! Here's some code that uses a `&str`:
-//!
-//! ```
-//! let s = "Hello, world.";
-//! ```
-//!
-//! This `&str` is a `&'static str`, which is the type of string literals.
-//! They're `'static` because literals are available for the entire lifetime of
-//! the program.
-//!
-//! You can get a non-`'static` `&str` by taking a slice of a `String`:
-//!
-//! ```
-//! let some_string = "Hello, world.".to_string();
-//! let s = &some_string;
-//! ```
-//!
-//! # Representation
-//!
-//! Rust's string type, `str`, is a sequence of Unicode scalar values encoded as
-//! a stream of UTF-8 bytes. All [strings](../../reference.html#literals) are
-//! guaranteed to be validly encoded UTF-8 sequences. Additionally, strings are
-//! not null-terminated and can thus contain null bytes.
-//!
-//! The actual representation of `str`s have direct mappings to slices: `&str`
-//! is the same as `&[u8]`.

 //! Raw, unsafe pointers, `*const T`, and `*mut T`
 //!
-//! Working with raw pointers in Rust is uncommon,
-//! typically limited to a few patterns.
-//!
-//! Use the `null` function to create null pointers, and the `is_null` method
-//! of the `*const T` type  to check for null. The `*const T` type also defines
-//! the `offset` method, for pointer math.
-//!
-//! # Common ways to create raw pointers
-//!
-//! ## 1. Coerce a reference (`&T`) or mutable reference (`&mut T`).
-//!
-//! ```
-//! let my_num: i32 = 10;
-//! let my_num_ptr: *const i32 = &my_num;
-//! let mut my_speed: i32 = 88;
-//! let my_speed_ptr: *mut i32 = &mut my_speed;
-//! ```
-//!
-//! To get a pointer to a boxed value, dereference the box:
-//!
-//! ```
-//! let my_num: Box<i32> = Box::new(10);
-//! let my_num_ptr: *const i32 = &*my_num;
-//! let mut my_speed: Box<i32> = Box::new(88);
-//! let my_speed_ptr: *mut i32 = &mut *my_speed;
-//! ```
-//!
-//! This does not take ownership of the original allocation
-//! and requires no resource management later,
-//! but you must not use the pointer after its lifetime.
-//!
-//! ## 2. Consume a box (`Box<T>`).
-//!
-//! The `into_raw` function consumes a box and returns
-//! the raw pointer. It doesn't destroy `T` or deallocate any memory.
-//!
-//! ```
-//! # #![feature(box_raw)]
-//! let my_speed: Box<i32> = Box::new(88);
-//! let my_speed: *mut i32 = Box::into_raw(my_speed);
-//!
-//! // By taking ownership of the original `Box<T>` though
-//! // we are obligated to put it together later to be destroyed.
-//! unsafe {
-//!     drop(Box::from_raw(my_speed));
-//! }
-//! ```
-//!
-//! Note that here the call to `drop` is for clarity - it indicates
-//! that we are done with the given value and it should be destroyed.
-//!
-//! ## 3. Get it from C.
-//!
-//! ```
-//! # #![feature(libc)]
-//! extern crate libc;
-//!
-//! use std::mem;
-//!
-//! fn main() {
-//!     unsafe {
-//!         let my_num: *mut i32 = libc::malloc(mem::size_of::<i32>() as libc::size_t) as *mut i32;
-//!         if my_num.is_null() {
-//!             panic!("failed to allocate memory");
-//!         }
-//!         libc::free(my_num as *mut libc::c_void);
-//!     }
-//! }
-//! ```
-//!
-//! Usually you wouldn't literally use `malloc` and `free` from Rust,
-//! but C APIs hand out a lot of pointers generally, so are a common source
-//! of raw pointers in Rust.
