Propagate reachability through reexported impls

When re-exporting a trait/structure/enum, then we need to propagate the
reachability of the type through the methods that are defined on it.

Closes #9906
Closes #9968
rustdoc: Don't overflow long type/module names

Closes #9862
rustdoc: Render default methods for impls as well

This does not work for cross-crate implementations of traits. Cross-crate
implementations are a separate issue that should be addressed separately.
Basically when an implementation of an external trait is detected, the trait
would have to be loaded at that time (or possibly sooner...). Rustdoc currently
doesn't have the proper infrastructure for adding this.

This patch is trivial, but it comes with a question. Does Mozilla need to own the copyright on code submitted to Rust?

The reason I ask is that, since the last time I submitted anything to a Mozilla project, I started working at Google, and they (by default) own the copyright on code that I write (even in my spare time). There's a process to assign copyright to another entity, and it should be a formality for something like this, but I'd still have to go through it if that's a requirement for Rust.

Anyway, I'm submitting this incredibly trivial thing because, if I have to go through that process for the first time, I'd like it to be for something that's trivial, so I can see how much of a hassle it is (if any) without having invested much time up front.

I didn't see anything about copyright in the Mozilla contributor's agreement, but I could have easily missed something somewhere else.

It seems like rusti has been removed, except for one reference in one Makefile. This reference breaks building rust on my computer because the "all-target" rule has rusti as a target.

make: *** No rule to make target `x86_64-unknown-linux-gnu/stage2/bin/rusti', needed by `all-target-x86_64-unknown-linux-gnu-host-x86_64-unknown-linux-gnu'.  Stop.

Removing this line fixes things for me.
