	Currently the rust allocator simply passes the size of the type Layout to krealloc(), and in theory the alignment requirement from the type Layout may be larger than the guarantee provided by SLAB, which means the allocated object is mis-aligned. Fix this by adjusting the allocation size to the nearest power of two, which SLAB always guarantees a size-aligned allocation. And because Rust guarantees that the original size must be a multiple of alignment and the alignment must be a power of two, then the alignment requirement is satisfied.

2022-09-28	rust: add `kernel` crate	Wedson Almeida Filho
	The `kernel` crate currently includes all the abstractions that wrap kernel features written in C. These abstractions call the C side of the kernel via the generated bindings with the `bindgen` tool. Modules developed in Rust should never call the bindings themselves. In the future, as the abstractions grow in number, we may need to split this crate into several, possibly following a similar subdivision in subsystems as the kernel itself and/or moving the code to the actual subsystems.
