Remove duplication of libstd docs.

This is literally a copy-paste, there's no need to have this duplication.

-## The standard library in detail
-
-The Rust standard library provides runtime features required by the language,
-including the task scheduler and memory allocators, as well as library
-support for Rust built-in types, platform abstractions, and other commonly
-used features.
-
-[`std`] includes modules corresponding to each of the integer types, each of
-the floating point types, the [`bool`] type, [tuples], [characters], [strings],
-[vectors], [managed boxes], [owned boxes],
-and unsafe and borrowed [pointers].  Additionally, `std` provides
-some pervasive types ([`option`] and [`result`]),
-[task] creation and [communication] primitives,
-platform abstractions ([`os`] and [`path`]), basic
-I/O abstractions ([`io`]), [containers] like [`hashmap`],
-common traits ([`kinds`], [`ops`], [`cmp`], [`num`],
-[`to_str`], [`clone`]), and complete bindings to the C standard library ([`libc`]).
-
-The full documentation for `std` can be found here: [standard library].

 ## The extra library
 
-Rust also ships with the [extra library], an accumulation of
-useful things, that are however not important enough
-to deserve a place in the standard library.
-You can use them by linking to `extra` with an `extern mod extra;`.
