Gary M. Josack 5123bf40a1 Update docs to fix various 404s
Found a few 404s that seemed like simple fixes:

The Result docs use old_io Writer as an example. Fix the link to old_io Writer. There's probably an effort to update the example away from a deprecated api but this was a simple fix.

rustc/plugin was pointing at the old guide and it was a broken link anyways (plugin vs plugins). Point at the book instead.

The main page of the API docs referenced c_{str,vec}. Looks like these were deleted in 25d5a3a19423fee01787de87a56d185dd4e0a4e7. Point at ffi docs instead.

//! Infrastructure for compiler plugins.
//!
//! Plugins are Rust libraries which extend the behavior of `rustc`
//! in various ways.
//!
//! Plugin authors will use the `Registry` type re-exported by
//! this module, along with its methods. The rest of the module
//! is for use by `rustc` itself.
//!
//! To define a plugin, build a dylib crate with a
//! `#[plugin_registrar]` function:
//!
//! ```rust,ignore
//! #![crate_name = "myplugin"]
//! #![crate_type = "dylib"]
//! #![feature(plugin_registrar)]
//!
//! extern crate rustc;
//!
//! use rustc::plugin::Registry;
//!
//! #[plugin_registrar]
//! pub fn plugin_registrar(reg: &mut Registry) {
//! reg.register_macro("mymacro", expand_mymacro);
//! }
//!
//! fn expand_mymacro(...) { // details elided
//! ```
//!
//! WARNING: We currently don't check that the registrar function
//! has the appropriate type!
//!
//! To use a plugin while compiling another crate:
//!
//! ```rust
//! #![feature(plugin)]
//! #![plugin(myplugin)]
//! ```
//!
//! See the [Plugins Chapter](../../book/plugins.html) of the book
//! for more examples.
