Vitaly Wool	1738796994	rust: support large alignments in allocations ... Add support for large (> PAGE_SIZE) alignments in Rust allocators. All the preparations on the C side are already done, we just need to add bindings for <alloc>_node_align() functions and start using those.

Vitaly Wool	7760b6421b	rust: add support for NUMA ids in allocations ... Add a new type to support specifying NUMA identifiers in Rust allocators and extend the allocators to have NUMA id as a parameter. Thus, modify ReallocFunc to use the new extended realloc primitives from the C side of the kernel (i.e. k[v]realloc_node_align/vrealloc_node_align) and add the new function alloc_node to the Allocator trait while keeping the existing one (alloc) for backward compatibility. This will allow to specify node to use for allocation of e. g. {KV}Box, as well as for future NUMA aware users of the API.

Danilo Krummrich	61c004781d	rust: alloc: implement Vmalloc allocator ... Implement `Allocator` for `Vmalloc`, the kernel's virtually contiguous allocator, typically used for larger objects, (much) larger than page size. All memory allocations made with `Vmalloc` end up in `vrealloc()`.
