Update description of float casts
...
https://github.com/rust-lang/rust/issues/15536 has been closed, there's no UB there, so let's stop linking to it. And for the same reasons (LLVM's assumption of the default floating point environment), f64->f32 and int->float casts do actually have a defined rounding mode, ties-to-even.

`unsafe` and `mod` are not magically linked, it’s entirely up to code authors to actively use privacy to limit limit the scope of unsafety and only expose safe APIs (or `unsafe fn`s).

The previous title suggested that `repr(isize)`, for example, was not valid.
I'm not sure if this is great wording, or whether we should add some examples, but I think we can improve the heading.

subtyping: clarify the concreteness of 'a in example

This matters because if 'a were free to choose, then the argument would
be trivial. But in reality the argument also holds if 'a was already
chosen, which is what makes lifetimes special.

Revert "Fix up links"
...
This reverts commit 7f1d1c6d9a7be5e427bace30e740b16b25f25c92.
The original commit was created because mdBook and rustdoc had
different generation algorithms for header links; now with
https://github.com/rust-lang/rust/pull/39966 , the algorithms
are the same. So let's undo this change.
... when I came across this problem, I said "eh, this isn't fun,
but it doesn't take that long." I probably should have just actually
taken the time to fix upstream, given that they were amenable. Oh
well!

Re-implement rustbook in terms of mdbook
...
mdbook has a lot of optional dependencies that we don't want, so instead
of using it directly, we re-build rustbook to use mdbook as a library.
For convenience' sake, we keep the same CLI interface as mdbook; the
only difference is that it only accepts build and test subcommands,
rather than the full range.
