Variable completions. (#3666)
In Nu we have variables (E.g. $var-name) and these contain `Value` types.
This means we can bind to variables any structured data and column path syntax
(E.g. `$variable.path.to`) allows flexibility for "querying" said structures.

Here we offer completions for these. For example, in a Nushell session the
variable `$nu` contains environment values among other things. If we wanted to
see in the screen some environment variable (say the var `SHELL`) we do:

```
> echo $nu.env.SHELL
```

with completions we can now do: `echo $nu.env.S[\TAB]` and we get suggestions
that start at the column path `$nu.env` with vars starting with the letter `S`
in this case `SHELL` appears in the suggestions.

Plugin: from_mp4 and UntaggedValue::duration fix (#3618)
* plugin: basic from_mp4 implementation

This patch introduces a very basic implementation of from_mp4, with only
a few bits of meta-data available. The rest of the available meta-data
(which is more than half left), will be included in a later patch

* Mp4: Almost all track metadata is implemented

Only meta-data that is not implemented is duration, facing some weird
issue I am going to check on later

* Mp4: All meta-data fields implemented

All meta-data fields that can be retrieved are now retrieved, with the
exception of duration for both tracks and the entire file itself because
there is still an issue. However, that will be fixed in the upcoming
patches

* fix: UntaggedValue::duration() serializes correctly now

Previous to this patch, there was an issue where when you would use
UntaggedValue::duration() it would result in an invalid JSONRPC
resulting string when using the protocol. This patch fixes this issue

* Mp4: Duration fixed for file and tracks

* plugins: Add plugin extra to src/plugins

* Mp4: Replace unwrap() with expect()

* Fix: Remove test mp4 file

Port random integer & decimal to engine-p + related refactoring (#3393)
* Implement minmax for Range; Simplify range command

* Port random integer to enginep; New FromValue impl

Now, FromValue is implemented for Tagged<Range> to allow extracting args
into this type.

* Make sure range value extraction fails properly

The range endpoint extraction methods now return error instead of
silently clipping the value. This now makes `random integer ..-4` fail
properly since -4 can't be cast as u64.

* Port random decimal to enginep & Refactor

This added a way to interpret Range limits as f64 and a Primitive helper
to get its value as f64.

A side effect of this commit is that it is now possible to specify the
command bounds as true decimals. E.g., `random decimal 0.0..3.14` does
not clip 3.14 to 3.

Playground infraestructure (tests, etc) additions. (#3179)
* Playground infraestructure (tests, etc) additions.

A few things to note:

* Nu can be started with a custom configuration file (`nu --config-file /path/to/sample_config.toml`). Useful for mocking the configuration on test runs.
* When given a custom configuration file Nu will save any changes to the file supplied appropiately.
* The `$nu.config-path` variable either shows the default configuration file (or the custom one, if given)
* We can now run end to end tests with finer grained control (currently, since this is baseline work, standard out) This will allow to check things like exit status, assert the contents with a format, etc)

* Remove (for another PR)

Split nu-cli into nu-cli/nu-engine (#2898)
We split off the evaluation engine part of nu-cli into its own crate. This helps improve build times for nu-cli by 17% in my tests. It also helps us see a bit better what's the core engine portion vs the part specific to the interactive CLI piece.

There's more than can be done here, but I think it's a good start in the right direction.

Implement exclusive and inclusive ranges with ..< and .. (#2541)
* Implement exclusive and inclusive ranges with .. and ..=

This commit adds right-exclusive ranges.

The original a..b inclusive syntax was changed to reflect the Rust notation.
New a..=b syntax was introduced to have the old behavior.

Currently, both a.. and b..= is valid, and it is unclear whether it's valid
to impose restrictions.

The original issue suggests .. for inclusive and ..< for exclusive ranges,
this can be implemented by making simple changes to this commit.

* Fix collect tests by changing ranges to ..=

* Fix clippy lints in exclusive range matching

* Implement exclusive ranges using `..<`

Data summarize reporting overhaul. (#2299)
Refactored out most of internal work for summarizing data opening
the door for generating charts from it. A model is introduced
to hold information needed for a summary, Histogram command is
an example of a partial usage. This is the beginning.

Removed implicit arithmetic traits on Value and Primitive to avoid
mixed types panics. The std operations traits can't fail and we
can't guarantee that. We can handle gracefully now since compute_values
was introduced after the parser changes four months ago. The handling
logic should be taken care of either explicitly or in compute_values.

The zero identity trait was also removed (and implementing this forced
us to also implement Add, Mult, etc)

Also: the `math` operations now remove in the output if a given column is not computable:

```

57af9b5040 Add Range and start Signature support
This commit contains two improvements:

- Support for a Range syntax (and a corresponding Range value)
- Work towards a signature syntax

Implementing the Range syntax resulted in cleaning up how operators in
the core syntax works. There are now two kinds of infix operators

- tight operators (`.` and `..`)
- loose operators

Tight operators may not be interspersed (`$it.left..$it.right` is a
syntax error). Loose operators require whitespace on both sides of the
operator, and can be arbitrarily interspersed. Precedence is left to
right in the core syntax.

Note that delimited syntax (like `( ... )` or `[ ... ]`) is a single
token node in the core syntax. A single token node can be parsed from
beginning to end in a context-free manner.

The rule for `.` is `<token node>.<member>`. The rule for `..` is
`<token node>..<token node>`.

Loose operators all have the same syntactic rule: `<token
node><space><loose op><space><token node>`.

The second aspect of this pull request is the beginning of support for a
signature syntax. Before implementing signatures, a necessary
prerequisite is for the core syntax to support multi-line programs.

That work establishes a few things:

- `;` and newlines are handled in the core grammar, and both count as
  "separators"
- line comments begin with `#` and continue until the end of the line

In this commit, multi-token productions in the core grammar can use
separators interchangably with spaces. However, I think we will
ultimately want a different rule preventing separators from occurring
before an infix operator, so that the end of a line is always
unambiguous. This would avoid gratuitous differences between modules and
repl usage.

We already effectively have this rule, because otherwise `x<newline> |
y` would be a single pipeline, but of course that wouldn't work.

e4226def16 Extract core stuff into own crates
This commit extracts five new crates:

- nu-source, which contains the core source-code handling logic in Nu,
  including Text, Span, and also the pretty.rs-based debug logic
- nu-parser, which is the parser and expander logic
- nu-protocol, which is the bulk of the types and basic conveniences
  used by plugins
- nu-errors, which contains ShellError, ParseError and error handling
  conveniences
- nu-textview, which is the textview plugin extracted into a crate

One of the major consequences of this refactor is that it's no longer
possible to `impl X for Spanned<Y>` outside of the `nu-source` crate, so
a lot of types became more concrete (Value became a concrete type
instead of Spanned<Value>, for example).

This also turned a number of inherent methods in the main nu crate into
plain functions (impl Value {} became a bunch of functions in the
`value` namespace in `crate::data::value`).
