Obsolete, no replacement. The mechanics here are mostly implementation details at this point.

Does a sanity check of the version numbers.

There's only one build-critical path in which perl is used, and it was to do a text replacement trivially achievable with sed(1).

I ported the indenter script because it [appears to be used][indenter], but removed check links because it appears to be entirely out of date.

As discussed with @aturon I added implementations of various op traits for references to built-in types which was already suggested by the ops reform RFC.

The 2nd commit updates the module documentation of core::ops to fully reflect the recent change from pass-by-reference to pass-by-value and expands on the implications for generic code.

r? @alexcrichton 

Removed use of unused LDPATH variable on Windows as is done for other platforms, and added GCC flag to ensure MINGW's ANSI compatible STDIO functions are used wherever available (required by jemalloc).

Without these changes it ends up setting the PATH twice, and the second time the PATH begins with `:` which is invalid.  Also the regular msvcrt printf-like functions would be used which don't understand stuff like %hhd and %z which jemalloc uses.

This change ought not to make any difference to the output but it fixes the build process for me since at least my build environment couldn't handle that broken path caused by LDPATH being empty.

Continuation of https://github.com/rust-lang/rust/pull/21428

Only made 2 changes:
1) Update the year to 2015 in LICENSE-MIT
2) Update the year in COPYRIGHT

No other changes were made.

It got accidentially reverted in 44440e5c.

This should have been done together with 56dcbd17 for rust-lang/rust#20361

Multiple people have asked me if this is a reference to Hacker News, and
I _certainly_ don't want to give them that impression.

This is caught in borrowck now, but catching in typeck is faster and improves diagnostics.

CC #17561.

closes #21402

cc @ExpHP (btw, this only covers arrays with arity up to 32)

611ef49f removed all the metrics stuff
from tests.mk, but this meant that `PLEASE_BENCH=1` no longer did
anything.

Fixes #21324.

**Breaking change**: `VecMap::into_iter` now consumes the `VecMap`. To fix it you should pass the VecMap by value instead of by reference.

Fixes #21384 

example:
let m = "hello \
           world";

`x in y` is more Pythonic than `y.find(x) != -1`. I believe it runs quite a bit faster as well (though it's probably not a bottleneck of the Travis builds):

```bash
$ python -m timeit '"abc".find("a") != -1'
1000000 loops, best of 3: 0.218 usec per loop
$ python -m timeit '"a" in "abc"'
10000000 loops, best of 3: 0.0343 usec per loop
```

After PR #19766 added implicit coersions `*mut T -> *const T`, the explicit casts can be removed.
(The number of such casts turned out to be relatively small).

Updated `tidy.py` to skip printing NOTEs if the [`TRAVIS`](http://docs.travis-ci.com/user/ci-environment/#Environment-variables) environment variable is set.

From std::markers to std::marker.

Having both "Right now" and "at the moment" in the same statement is redundant.
