Impl Clone for DefaultHasher
It's useful for a hasher to be `Clone`. It's also strange for any type to not be `Clone`. `DefaultHasher` is not meant to be used directly, but being in std it can be useful as a placeholder. I don't see any forward compatibility hazard if the hasher is changed since it's very rare for something to not be `Clone`.

Better Debug for Args and ArgsOs
Display actual args instead of two dots.

Implement Sync for SyncSender

Display actual args instead of two dots.

This is an API that allows types to indicate that they can be passed
buffers of uninitialized memory which can improve performance.

add `FromStr` Impl for `char`
fixes #24939.
is it possible to use pub(restricted) instead of using a stability attribute for the internal error representation? is it needed at all?

Allocator integration
Lets start getting some feedback on `trait Alloc`.
Here is:
* the `trait Alloc` itself,
* the `struct Layout` and `enum AllocErr` that its API relies on
* a `struct HeapAlloc` that exposes the system allocator as an instance of `Alloc`
* an integration of `Alloc` with `RawVec`
* ~~an integration of `Alloc` with `Vec`~~
TODO
* [x] split `fn realloc_in_place` into `grow` and `shrink` variants
* [x] add `# Unsafety` and `# Errors` sections to documentation for all relevant methods
* [x] remove `Vec` integration with `Allocator`
* [x] add `allocate_zeroed` impl to `HeapAllocator`
* [x] remove typedefs e.g. `type Size = usize;`
* [x] impl `trait Error` for all error types in PR
* [x] make `Layout::from_size_align` public
* [x] clarify docs of `fn padding_needed_for`.
* [x] revise `Layout` constructors to ensure that [size+align combination is valid](https://github.com/rust-lang/rust/pull/42313#issuecomment-306845446)
* [x] resolve mismatch re requirements of align on dealloc. See [comment](https://github.com/rust-lang/rust/pull/42313#issuecomment-306202489).

Introduce tidy lint to check for inconsistent tracking issues
This PR
* Refactors the collect_lib_features function to work in a
non-checking mode (no bad pointer needed, and list of
lang features).
* Introduces checking whether unstable/stable tags for a
given feature have inconsistent tracking issues, as in,
multiple tracking issues per feature.
* Fixes such inconsistencies throughout the codebase.

Fix condvar.wait(distant future) return immediately on OSX
Fixes issue #37440: `pthread_cond_timedwait` on macOS Sierra seems
to overflow `ts_sec` parameter and returns immediately. To work
around this problem patch rounds timeout down to year 3000.
Patch also fixes overflow when converting `u64` to `time_t`.

Add a travis builder for wasm32-unknown-emscripten
This commits add an entry to travis matrix that will execute wasm32-unknown-emscripten tests suites.
- Emscripten for asmjs was updated to sdk-1.37.13-64bit
- The tests are run with node 8.0.0 (it can execute wasm)
- A wrapper script is used to run each test from the directory where it is (workaround for https://github.com/kripken/emscripten/issues/4542)
- Some tests are ignore, see #42629 and #42630

Remove sometimes in std::io::Read doc
We use it immediately in the next sentence, and the word is filler.
A different conversation to make is whether we want to call them Readers in the documentation at all. And whether it's actually called "Readers" elsewhere.

Fixes issue #37440: `pthread_cond_timedwait` on macOS Sierra seems
to overflow `ts_sec` parameter and returns immediately. To work
around this problem patch rounds timeout down to approximately 1000
years.

Build instruction profiler runtime as part of compiler-rt
r? @alexcrichton
This is #38608 with some fixes.
Still missing:
- [x] testing with profiler enabled on some builders (on which ones? Should I add the option to some of the already existing configurations, or create a new configuration?);
- [x] enabling distribution (on which builders?);
- [x] documentation.
