Struct and enum representations have some complicatedness that's no longer needed. Now that everything's in one place and has access to anything we'd want to know about the type, flatten some of that out. Slight changes to representations in some cases.
The only thing we really lose is that C-like enums with one variant and a
non-zero discriminant now take up space, but I do not think this is a
common usage. As previously noted, that was mostly there for
transitional compatibility with the pre-adt.rs codebase.
Out goes the extra layer of struct wrapping; the destructedness flag is
added to the end of the struct. This means that, if the struct
previously had alignment padding at the end, the flag will live there
instead of increasing the struct size.
There were three issues effecting the example in the getopts rustdoc:
1. The blockquote was incorrectly formatted. Fixed by switching to using
an explicit markdown code section with ```.
2. The `fail fail_str(f)` would not compile. Fixed by using `fail!()` instead
of `fail`.
3. The line `matches.free[0]` produced a compile error about moving from
an immutable vector. Fix by using `copy`.
Previous year range of 2011-2013 was based on file creation date. The
check_license python script, however, only accepts copyrights starting
in 2012 or later.

Without this change, rust-mode doesn't work if 'cl hasn't been required
by something else, apparently. I'm not entirely sure what changed such
that I started seeing this problem instead of not, but maybe the emacs
world has been making progress towards not loading 'cl at runtime if
it's only needed at compile time.

`log` can polymorphically log anything, but debug!, etc. requires a format string. With this patch you can equivalently write `debug!(foo)` or `debug!("%?", foo)`.
I'm doing this because I was trying to remove `log` (replacing it with nothing, at least temporarily), but there are a number of logging statements that just want to print an arbitrary value and don't care about the format string.
I'm not entirely convinced this is a good change, since it overloads the implementation of these macros and makes their usage slightly more nuanced.
