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]`.
//! *[See also the `str` primitive type](../primitive.str.html).*

//! 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.

/// 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]`.

//! The `()` type, sometimes called "unit" or "nil".
//!
//! The `()` type has exactly one value `()`, and is used when there
//! is no other meaningful value that could be returned. `()` is most
//! commonly seen implicitly: functions without a `-> ...` implicitly
//! have return type `()`, that is, these are equivalent:

//! ```rust

//!
//! fn short() {}
//! ```
//!
//! The semicolon `;` can be used to discard the result of an
//! expression at the end of a block, making the expression (and thus
//! the block) evaluate to `()`. For example,
//!
//! ```rust
//! fn returns_i64() -> i64 {
//! 1i64
//! }
//! fn returns_unit() {
//! 1i64;
//! }
//!
//! let is_i64 = {
//! returns_i64()
//! };
//! let is_unit = {
//! returns_i64();
//! };
//! ```
