* WIP: Start laying overlays
* Rename Overlay->Module; Start adding overlay
* Revamp adding overlay
* Add overlay add tests; Disable debug print
* Fix overlay add; Add overlay remove
* Add overlay remove tests
* Add missing overlay remove file
* Add overlay list command
* (WIP?) Enable overlays for env vars
* Move OverlayFrames to ScopeFrames
* (WIP) Move everything to overlays only
ScopeFrame contains nothing but overlays now
* Fix predecls
* Fix wrong overlay id translation and aliases
* Fix broken env lookup logic
* Remove TODOs
* Add overlay add + remove for environment
* Add a few overlay tests; Fix overlay add name
* Some cleanup; Fix overlay add/remove names
* Clippy
* Fmt
* Remove walls of comments
* List overlays from stack; Add debugging flag
Currently, the engine state ordering is somehow broken.
* Fix (?) overlay list test
* Fix tests on Windows
* Fix activated overlay ordering
* Check for active overlays equality in overlay list
This removes the -p flag: Either both parser and engine will have the
same overlays, or the command will fail.
* Add merging on overlay remove
* Change help message and comment
* Add some remove-merge/discard tests
* (WIP) Track removed overlays properly
* Clippy; Fmt
* Fix getting last overlay; Fix predecls in overlays
* Remove merging; Fix re-add overwriting stuff
Also some error message tweaks.

* Add two more overlay tests
* Add ModuleId to OverlayFrame
* Fix env conversion accidentally activating overlay
It activated overlay from permanent state prematurely which would
cause `overlay add` to misbehave.
* Remove unused parameter; Add overlay list test
* Remove added traces
* Add overlay commands examples
* Modify TODO
* Fix $nu.scope iteration
* Disallow removing default overlay
* Refactor some parser errors
* Remove last overlay if no argument
* Diversify overlay examples
* Make it possible to update overlay's module
In case the origin module updates, the overlay add loads the new module,
makes it overlay's origin and applies the changes. Before, it was
impossible to update the overlay if the module changed.

Prior to this change we would recover the names for known
externals by looking up the span in the engine state. This would fail
when using an alias for two reasons:
1. In cases where we don't have a subcommand, like this:
```
>>> extern bat [filename: string]
>>> alias b = bat
>>> bat some_file
'b' is not recognized as an internal or external command,
operable program or batch file.
```
The problem is that after alias expansion, we replace the span of the
expanded name with the original alias (this is done to alleviate
non-related issues). The span contents we look up therefore contain `b`,
the alias, instead of the expanded command name.
2. In cases where there's a subcommand:
```
>>> alias g = git
>>> g push
thread 'main' panicked at 'internal error: span missing in file contents cache', crates\nu-protocol\src\engine\engine_state.rs:474:9
note: run with `RUST_BACKTRACE=1` environment variable to display a
backtrace
```
In this case, the span in call starts where the expansion for the `g`
alias is defined and end after `push` on the last command entered. This
is not a proper span and causes a panic when we try to look it up. Note
that this is the case for all expanded aliases that involve a
subcommand, but we never actually try to retrieve the contents for that
span in other cases.
Anyway, the new way of looking up the name is arguably cleaner
regardless of the issues mentioned above. But it's nice that it fixes
them too.
