This PR intended to reduce stream usage scope in order to make AquaVM truly deterministic.

* Introduce multiline call annotations
Call annotations have same format as `;`-annotations, but can allow
multiline JSON literals. They look like `#| ... |#` (that's Common Lisp syntax for multiline comments).
For example:
```
(call "peer_id" ("serv" "func") [a b] var) #|
map = {
"0": null,
"default": 42,
}
|#
```
* A JSON in the assertion parser doesn't have be last
We have been using nom's `rest` for JSON values. Now we have a simple JSON parser
that recognizes JSON to be parsed with `serde_json`, and may have multiple JSON objects
within same assertion.
* Allow annotation after a compound form
It is attached to a rightmost nested element that has to be a `call` special form.
The current peer ID is passed as a new field of `TestRunParameters` named
`current_peer_id: String`, instead of creating an AVM with peer ID.
This is a breaking API change of `avm-interface` and `avm-server`.
1. Network can be shared between several execution, being used by an Rc-handle.
2. The neighborhood is just network's all peers with removed/inserted hosts delta with respect to network.
3. An AIR script is transformed into a separate value of type `TransformedAirScript`. It allows running several
particles on the same parsed AIR script, sharing state.
4. `TestExecutor` was renamed to `AirScriptExecutor`. It also has a constructor that accepts a `TransformedAirScript`.
Try to parse the annotated AIR script with the standard parser to catch
to catch errors early with better error messages.
We do it in the `TestExecutor` only to make testing framwork parser
tests simplier. For user experience, it doesn't matter.
* seq_result` -> `seq_ok`; add `seq_err`
`seq_ok` and `seq_err` are consistent with `ok` and `err`, but produce
results sequentially.
* Accept `;;` and longer comments in the sexp parser
Currently they are just dropped, and resulting AIR has different
character positions in the error messages.
* Add "map" assertion
Lookup result in a map by service's first argument.
Validator checks that stream used in `canon` is populated by a value in a supplied script. This PR removes this check, because it's useful for code generation.
At the moment `Ap` state contains vector of generations, although the ap instruction itself allow to specify only one stream. It was done to support several streams in a result position in a future. But the current realization allows to handle empty vector that was implemented to support states for scalars and it turned out (for more info see #326) that states for scalars aren't actually needed.
Closes#355.
This PR refactors call merger of `TraceHandler`. Previously it requires `CallOutputValue` to determine a type of call output value (stream or scalar). And internally it checked correspondence between data result and call output type and return a error if they are not equal. Although execution engine component also had a match over these values and does nothing if they are not matched since `TraceHandler` did this job. This PR eliminate such behaviour and improve isolation of AquaVM modules.
feat(execution-engine): change behaviour of fold over streams
Change behaviour of fold over streams to make it more similar to pi-calculus channels/names (for more info see #333).
Closes#333.
BREAKING CHANGE:
The new stream behaviour is not compatible with old one, such as
```
(fold $stream iterator
(seq
(call ...)
(next iterator)))
```
will never end after this change (for more info again see #333).
* Get rid of unsafe code unless really necessary
* Add lint levels where appropriate
Some crates (air-beautifier, air-testing-framework) have lot of
rust_2018_idioms violations, that will be resolved later.
Testing framework for AquaVM
Its primary features are:
1. It generates services declaratively by annotation in the comments inserted just after calls.
2. Ephemeral network keeps each node's data and incoming data queue. The network can be also generated based on peer IDs featured in the script.
3. One can explicitly add additional peers and services.
The example of the script annotations:
```
(seq
(call "peer_1" ("service" "func") [] var) ; ok=42
(call "peer_2" ("service" "func") [var]) ; err={"ret_code": 1, "result":"no towel"}
)
```
Passing this script to `air_test_framework::TestExecutor::new(...)` will create a virtual network with peers "peer_1" and "peer_2" (and any peer you provide in the `TestRunParameters`), and the particular calls will return respective values.
Please note that autogenerated services use modified service name as a side channel for finding a correct value: "..{N}" is added to each service name (two dots and serial number). Be careful with service names taken from a variable.
* Refactor `avm-server` interface mod to new crate (#294)
The new crate name is `avm-interface`.
It allows to build fully native air-trace, including pure WASM build.
* Make fully native air-trace build
Unless `wasm` feature is enabled (default), fully native build is
produced. You may build WASM air-trace binary with
`cargo build --target wasm32-wasi --no-default-features --release -p air-trace`
* Fix tracing output on native air-trace build
Wrong option was used.
