I keep having 3+ PR's in at the same time and always deal with crazy
conflicts because everything in the `ext` library is together in one
file.
This PR moves each category of extension into its own file, and
separates the `vfs` functionality in Core into the `ext/dynamic` module,
so that it can be more easily separated from wasm (or non feature =
"fs") targets to prevent build issues.
The only semantic changes made in this PR is the feature gating of vfs,
the rest is simply organizing and cleaning up imports.
Was unsure if `vfs` should be a feature on the `core` side too, or to
just enable it with the `fs` feature which seemed reasonable, as that
was already the current behavior. But let me know if we want it entirely
behind it's own feature.

Add basic printf function support in limbo

Closes#886
First review #820
The function follows RFC 7386 JSON Merge Patch semantics:
* If the patch is null, the target is replaced with null
* If the patch contains a scalar value, the target is replaced with that
value
* If both target and patch are objects, the patch is recursively applied
* null values in the patch result in property removal from the target
Closes#821
Relates to #127. This PR is still in draft and I have a few left things
to do (tests, improve implementation), just opening it so anyone can
track this work meanwhile.
Closes#664
This is a purely syntactic PR. It doesn't change behavior, just rewrites
some loops and removes unneeded parts, like lifetime annotations and
references. Mainly because the Clippy and IDE warnings get annoying.
Don't worry about the number of commits, I just separated based on type
of change.
Closes#732
