This moves the raw struct layout of closures, vectors, boxes, and strings into a
new `unstable::raw` module. This is meant to be a centralized location to find
information for the layout of these values.
As safe method, `unwrap`, is provided to convert a rust value to its raw
representation. Unsafe methods to convert back are not provided because they are
rarely used and too numerous to write an implementation for each (not much of a
common pattern).
This is progress on #6790. I tried to get a nice interface for a trait to implement in the raw module, but I was unable to come up with one. The hard part is that there are so many different directions to go from one way to another that it's difficult to find a pattern to follow to implement a trait with. Someone else might have some better luck though.

First, clean up the uses of "None" and "Some" to always use consistent title case matching the variant names.
Add .chain_mut_ref() which is a missing method. A use case example for this method is extraction of an optional value from an Option\<Container\> value.
This is a cleanup pull request that does:
* removes `os::as_c_charp`
* moves `str::as_buf` and `str::as_c_str` into `StrSlice`
* converts some functions from `StrSlice::as_buf` to `StrSlice::as_c_str`
* renames `StrSlice::as_buf` to `StrSlice::as_imm_buf` (and adds `StrSlice::as_mut_buf` to match `vec.rs`.
* renames `UniqueStr::as_bytes_with_null_consume` to `UniqueStr::to_bytes`
* and other misc cleanups and minor optimizations
My first bit of newsched IO work. Pretty simple and limited in scope.
the RtioTimer trait only has a `sleep(msecs: u64)` method, for now. Taking requests on what else ought to be here.
oh yeah: this resolves#6435
This removes all the code from libextra that depends on libuv. After that it removes three runtime features that existed to support the global uv loop: weak tasks, runtime-global variables, and at_exit handlers.
The networking code doesn't have many users besides servo, so shouldn't have much fallout. The timer code though is useful and will probably break out-of-tree code until the new scheduler lands, but I expect that to be soon.
It also incidentally moves `os::change_dir_locked` to `std::unstable`. This is a function used by test cases to avoid cwd races and in my opinion shouldn't be public (#7870).
Closes#7251 and #7870
