At some point, this should be done inside LinkedList itself, but we have no such thing as break in for_each().
It's iterate over everything or nothing.
This also requires operator= in Option, might be also added to Result in the future.

Add a 'pure' variant of cstyle_format which is infallible

If we cannot fail to output, it doesn't make sense to propagate errors. So if you're SURE there are no errors, use pure_cstyle_format().
If, however, output can fail, use cstyle_format().
This has a drawback of adding quite a bit of code duplication to Format.cpp.
Some of it is dealt using templates, but some code still remains duplicate.

Here's one advantage of Rust over C++:
Immutability by default. In Rust, you have to mark a variable as mutable, whereas in C++ you have to mark it as immutable.
What's the problem here? Usually, most variables don't need mutability. Thus we end up with const all over the place.

Please use make<T> and destroy<T> instead of new and delete

Those are there only for common stuff (in the Luna library) that needs an environment-agnostic way of allocating memory.
new and delete are standard, thus we should use those.

Kernel: Add a heap memory allocator
...
This is the first time I've actually dropped liballoc in favor of writing my own implementation.
Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job.
But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!
