Colin Walters f065c0dd32 Add --enable-sanitizers (not on by default yet) 
This way we at least get unit test coverage (which...
our unit test coverage doesn't do much because our
main code paths require privileges or virt).

One main blocker to this is that rustc doesn't expose
first-class support for this yet:
https://github.com/rust-lang/rust/issues/39699

At a practical level this works when building in release
mode but fails with `cargo test` for some reason; linker
arguments being pruned?  Not sure.

So I was able to use this when composing to find a bug,
but then for some other reason the client
side apparently infinite loops inside libsolv.

So we're not enabling this yet for those reasons, but
let's land the build infrastructure now.

rpm-ostree: A true hybrid image/package system

rpm-ostree is a hybrid image/package system. It combines libostree as a base image format, and accepts RPM on both the client and server side, sharing code with the dnf project; specifically libdnf. and thus bringing many of the benefits of both together.

Features:

  • Transactional, background image-based (versioned/checksummed) upgrades
  • OS rollback without affecting user data (/usr but not /etc, /var) via libostree
  • Client-side package layering (and overrides)
  • Easily make your own: rpm-ostree compose tree and CoreOS Assembler
