Fix link to rustc_* TEST attributes in ui.md

1. added two new parts: Bootstrapping and Supporting Infrastructure; 2. touched up names of pre-existing parts, to match actual names in sidebar; 3. syntactic nits (start description of Analysis with a capital letter); and 4. make numbered list use only 1.

This updates the exploit mitigations chapter in the rustc book to use the footnote feature of mdbook instead of manually implementing footnotes with HTML.

Prior to this commit, the transmutability analysis used an intermediate NFA representation of type layout. We then determinized this representation into a DFA, upon which we ran the core transmutability analysis. Unfortunately, determinizing NFAs is expensive. In this commit, we avoid NFAs entirely by observing that Rust `union`s are the only source of nondeterminism and that it is comparatively cheap to compute the DFA union of DFAs. We also implement Graphviz DOT debug formatting of DFAs. Fixes rust-lang/project-safe-transmute#23 Fixes rust-lang/project-safe-transmute#24
