68583a25a0 core::rt: Restructure context switches to take ownership of the Scheduler
In order to do a context switch you have to give up ownership of the scheduler,
effectively passing it to the next execution context. This could help avoid
some situations here tasks retain unsafe pointers to schedulers between context
switches, across which they may have changed threads.

There are still a number of uses of unsafe scheduler pointers.

dd2c7f61a9 auto merge of #5879 : astrieanna/rust/document_std_base64, r=catamorphism
This adds examples for the methods in std::base64.

Each example is complete in the sense that you can copy-paste it into a file and compile it successfully without adding anything (imports, etc). The hardest part of figuring out how to use this was figuring out the right import statements to put at the top.

r? @graydon

Pulled out tests into their own modules inside the files they test,
as per the draft style guidelines.

Started a new module, path_util, for utility functions to do with
paths and directories.

Changed default_dest_dir to use a condition and return Path
instead of Option<Path>.

4beebc427c auto merge of #5797 : alexcrichton/rust/issue-1913, r=catamorphism
Closes #5487, #1913, and #4568

I tracked this by adding all used unsafe blocks/functions to a set on the `tcx` passed around, and then when the lint pass comes around if an unsafe block/function isn't listed in that set, it's unused.

I also removed everything from the compiler that was unused, and up to stage2 is now compiling without any known unused unsafe blocks.

I chose `unused_unsafe` as the name of the lint attribute, but there may be a better name...

9b55d86e74 Prevent eval_const_expr_partial hides prior error in expr_cast arm.
This will help not to meet confusing errors.
In issue #5873, the error was "expected constant expr for vector length: Can't cast str to int".
It was originally "expected constant expr for vector length: Non-constant path in constant expr"
This patch make the original error to be printed.

3809a04bf7 auto merge of #5778 : jld/rust/reflect-abstract-enum, r=graydon
This takes care of one of the last remnants of assumptions about enum layout.  A type visitor is now passed a function to read a value's discriminant, then accesses fields by being passed a byte offset for each one.  The latter may not be fully general, despite the constraints imposed on representations by borrowed pointers, but works for any representations currently planned and is relatively simple.

Closes #5652.

This is a follow-up to #5761. Its purpose is to make core::libc more consistent - it currently only defines SIGKILL and SIGTERM, because they are the only values that happen to be needed by libcore.

This adds all the posix signal value constants, except for those that have different values on different architectures.

The output of the command `man 7 signal` was used to compile these signal values.

The foldl based implementation allocates lots of unneeded vectors.
iter::map_to_vec is already optimized to avoid these.

One place that benefits quite a lot from this is the metadata decoder, helping with compile times for tiny programs.

715810290f auto merge of #5810 : thestinger/rust/iterator, r=graydon
The current protocol is very comparable to Python, where `.__iter__()` returns an iterator object which implements `.__next__()` and throws `StopIteration` on completion. `Option` is much cleaner than using a exceptions as a flow control hack though. It requires that the container is frozen so there's no worry about invalidating them.

Advantages over internal iterators, which are functions that are passed closures and directly implement the iteration protocol:

* Iteration is stateful, so you can interleave iteration over arbitrary containers. That's needed to implement algorithms like zip, merge, set union, set intersection, set difference and symmetric difference. I already used this internally in the `TreeMap` and `TreeSet` implementations, but regions and traits weren't solid enough to make it generic yet.
* They provide a universal, generic interface. The same trait is used for a forward/reverse iterator, an iterator over a range, etc. Internal iterators end up resulting in a trait for each possible way you could iterate.
* They can be composed with adaptors like `ZipIterator`, which also implement the same trait themselves.

The disadvantage is that they're a pain to write without support from the compiler for compiling something like `yield` to a state machine. :)

This can coexist alongside internal iterators since both can use the current `for` protocol. It's easier to write an internal iterator, but external ones are far more powerful/useful so they should probably be provided whenever possible by the standard library.

## Current issues

#5801 is somewhat annoying since explicit type hints are required.

I just wanted to get the essentials working well, so I haven't put much thought into making the naming concise (free functions vs. static `new` methods, etc.).

Making an `Iterable` trait seems like it will have to be a long-term goal, requiring type system extensions. At least without resorting to objects which would probably be unacceptably slow.

This restores the trait that was lost in 216e85fadf. `Num` will eventually be broken up into a more fine-grained trait hierarchy in the future once a design can be agreed upon.

To contribute to the discussion about the future of Rust's numeric traits, please see issue #4819 and the [wiki page](https://github.com/mozilla/rust/wiki/Bikeshed-Numeric-Traits).

I have also switched to [implementing NumCast using macros](353ce872e2). This removes a significant number of lines of code.

78bc10d94b Doc review, as requested :-).
Mostly just phrasing things differently, which is a matter of taste. Feel free to use or not use any of the changes I'm suggesting.

I would say this one thing should be changed, though, not necessarily the way I changed it here.

     * Convert any string (literal, `@`, `&`, `~`)
     * that contains a base64 encoded value, to the byte values it encodes.

If this structure is going to be used, either the entire clause, 'that contains a base64 encoded value', should be bracketed by commas, or the comma at the end of the clause should be removed.
