hg-core: add basic config module

The config module exposes a `Config` struct, unused for now.

It only reads the config file local to the repository, but handles all valid
patterns and includes/unsets.
It is structured in layers instead of erasing by reverse order of precedence,
allowing us to transparently know more about the config for debugging purposes,
and potentially other things I haven't thought about yet.

This change also introduces `format_bytes!` to `hg-core`.
