Colin Walters 10ad264ecd daemon: Heap allocate GVariantDict to pass to Rust 
I was looking at a different problem and noticed a spam of
```
Feb 24 23:06:37 cosa-devsh rpm-ostree[1099]: g_variant_dict_ref: assertion 'is_valid_heap_dict (dict)' failed
Feb 24 23:06:37 cosa-devsh rpm-ostree[1099]: g_variant_dict_unref: assertion 'is_valid_heap_dict (dict)' failed
Feb 24 23:06:37 cosa-devsh rpm-ostree[1099]: g_variant_dict_ref: assertion 'is_valid_heap_dict (dict)' failed
Feb 24 23:06:37 cosa-devsh rpm-ostree[1099]: g_variant_dict_unref: assertion 'is_valid_heap_dict (dict)' failed
```

in the journal.  It turns out that the Rust bindings try to call
`g_variant_ref()`, but that's (understandably) not allowed on
a stack allocated instance.

Since we heap allocate a *ton* here, let's just heap allocate
the dict too.

Now, we also along the way stopped using the bits to inject
```
[Service]
Environment=G_DEBUG=fatal-warnings
```
in our CI.  I'll look at that as a followup.

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
