std: Internalize almost all of `std::rt`
...
This commit does some refactoring to make almost all of the `std::rt` private.
Specifically, the following items are no longer part of its API:
* DEFAULT_ERROR_CODE
* backtrace
* unwind
* args
* at_exit
* cleanup
* heap (this is just alloc::heap)
* min_stack
* util
The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is
an entry point for the `panic!` macro via the `begin_unwind` and
`begin_unwind_fmt` reexports.

Rustonomicon: Fix bug in implementation of Vec::drain()
...
In the last code snippet on the following page there is a bug in the
implementation of Vec::drain().
https://doc.rust-lang.org/nightly/nomicon/vec-drain.html
```rust
pub fn drain(&mut self) -> Drain<T> {
// Oops, setting it to 0 while we still need the old value!
self.len = 0;
unsafe {
Drain {
// len is used to create a &[T] from &self here,
// so we end up always creating an empty slice.
iter: RawValIter::new(&self),
vec: PhantomData,
}
}
}
```
A simple test to verify that Drain is broken can be found here:
https://play.rust-lang.org/?gist=30f579565e4bbf4836ce&version=nightly
And here's one with a fixed implementation:

Revise TARPL's description for allocating 0 bytes
...
In Section 3.2, TARPL says that "standard allocators (including jemalloc, the one used by default in Rust) generally consider passing in 0 for the size of an allocation as Undefined Behaviour."
However, the C standard and jemalloc manual says allocating zero bytes
should succeed:
- C11 7.22.3 paragraph 1: "If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object."
- [jemalloc manual](http://www.freebsd.org/cgi/man.cgi?query=jemalloc&sektion=3 ): "The malloc and calloc functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set to ENOMEM."
+ Note that the description for `allocm` says "Behavior is undefined if size is 0," but it is an experimental API.
