Don't move the data when extracting the bytes in XMLHttpRequest::Send.

The data is used later to set the Content-Type header. Current rustc
(4d2af3861) does not detect this use-after-move, but treats the later use as
if the data was None. It will, however, detect the bug in d2b30f7d3, which we
are upgrading to.

Enable rustdoc for the style crate. Fix #2924.

We’re now at a Rust version that has a fix for
https://github.com/rust-lang/rust/issues/16274
Add a 'mach rust-root' command.
Have the Rust snapshot directory include the Rust version and hash.

That way, whenever rust-snapshot-hash changes, mach will look for
the Rust snapshot in a different directory and re-boostrap as needed.

However, older rust version will be left behind never cleaned up.
This is good for git-bisect, but not for disk space:
the current snapshot is 618 MB.

In the future, we may want `mach clean` or some other comment
to remove unused Rust snapshots.

The biggest language change is that enum variants now also reserve (for future use) a name in the type namespace, which must not collide with other types. Some things were renamed, and others qualified as `module::name`.
