Split old and experimental wasm builders
#42784 introduced configuration errors in the wasm builder by mixing different versions of the tools. This PR separates the wasm32-unknown-emscripten and wasm32-experimental-emscripten builders to resolve these errors.
This adds a pretty contrived example of the usage of fmt::Error. I am
very open to suggestions for a better one.
I have also highlighted the fmt::Error vs std::error::Error.

This precondition takes the form of a behavorial change in
`Layout::from_size_align` (so it returns `None` if the `align` is too
large) and a new requirement for safe usage of
`Layout::from_size_align_unchecked`.
Fix#30170.
Notably pull in an update to the `jobserver` crate to have Cargo set the
`CARGO_MAKEFLAGS` environment variable instead of the `MAKEFLAGS` environment
variable.
Implement fs::rename in sys::redox
This uses a simple implementation of copy + unlink. Redox does not have a rename or link system call for a faster implementation.

update .mailmap
It's nice to have an up-to-date .mailmap so that contributor listings (like those provided by `git shortlog` or http://thanks.rust-lang.org/) don't split the same author's contributions across two or more variations of their name.

Document what happens on failure in path ext is_file is_dir

Also, what other ways could there be an error that gets discarded and returns false? Should we list them all? Should we say that any errors trying to access the metadata at that path causes it to return false, even if there might be a file or directory there?
Should I add a See also link to the original functions that do return Results?
Thread local try with
https://github.com/rust-lang/rfcs/pull/2030 was turned into this PR (the RFC was closed, but it looks like just a PR should be good).
See also: state stabilization issue: #27716
`try_with` is used in two places in std: stdio and thread_info. In stdio, it would be better if the result was passed to the closure, but in thread_info, it's better as is where the result is returned from the function call. I'm not sure which is better, but I prefer the current way as it better represents the scope.
Updated docker images to share scripts
Attempts to resolve#42201. I managed to pull out five scripts (android-base-apt-get, ubuntu16-apt-get, make3, rustbuild-setup, and crosstool-ng). Let me know if there's more I can do or if I should change some names.
