Feat: prototype of self-hosted library

This is very much a work in progress. Still ruminating on the structure
of the library. It feels right but I want a more "social" presence -
namely the ability to link to a libc seemlessly. The solution is most
likely weak aliasing that musl uses - but musl itself weak aliases
global symbols, e.g malloc. We would have to define weak internal
symbols that musl defines as strong links but this knows too much about
the internals of musl...
