This commit enhances documentation with several links and
fixes an error in the `sync_channel` documentation as well:
`send` doesn't panic when the senders are all disconnected

When an item is defined in an external macro it doesn't get a real
filename so we need to filter out these when generating src links for
reexported items.

Avoid using locally installed Source Code Pro font (fixes rust-lang#24355).

In some versions of this font the ampersands are drawn badly.

A doc tree built with this change is at https://storage.googleapis.com/mbp-rust-builds/fonts/doc/std/index.html

I'm not seeing this problem locally so I'm not sure this fixes it, but based on the diagnosis in the bug it should.

I've made this a minimal change by only removing the one problematic font but maybe for consistency every font should be read from the Rust docs tree?

filename so we need to filter out these when generating src links for
reexported items.
