Discussion: Provide a libc module similar to the original one

[tbu-]

Most implementations (e.g. in src/sys/linux/fs.rs) just require changing the original std code by replacing libc with something like linux or errno. I suggest that we build most of the abstractions (those that are possible to do) in a separate module called libc in the root namespace, so that we can use the original std code with less modifications (should make updating easier).

What do you think?

This seems to be accepted.
