This commit changes implementation of module loading in "deno_core"
to track all currently fetched modules across all existing module loads.
In effect a bug that caused concurrent dynamic imports referencing the
same module to fail is fixed.
This commit adds support for piping console messages to inspector.
This is done by "wrapping" Deno's console implementation with default
console provided by V8 by the means of "Deno.core.callConsole" binding.
Effectively each call to "console.*" methods calls a method on Deno's
console and V8's console.
This commit moves bulk of the logic related to module loading
from "JsRuntime" to "ModuleMap".
Next steps are to rewrite the actual loading logic (represented by
"RecursiveModuleLoad") to be a part of "ModuleMap" as well --
that way we will be able to track multiple module loads from within
the map which should help me solve the problem of concurrent
loads (since all info about currently loading/loaded modules will
be contained in the ModuleMap, so we'll be able to know if actually
all required modules have been loaded).
`init()` was previously needed to init the shared queue, but now that it's
gone `init()` only registers the async msg handler which is snapshot
safe and constant since the op layer refactor.
Also cleanup `bindings::deserialize()/decode()` so they
use the `ZeroCopyBuf` abstraction rather than reimplementing it.
This cleanup will facilitate moving `ZeroCopyBuf` to `serde_v8`
since it's now self contained and there are no other
`get_backing_store_slice()` callers.
- Improves op performance.
- Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs
per op-encoding (aka: out-of-payload).
- Remove shared queue & custom "asyncHandlers", all async values are
returned in batches via js_recv_cb.
- The op-layer should be thought of as simple function calls with little
indirection or translation besides the conceptually straightforward
serde_v8 bijections.
- Preserve concepts of json/bin/min as semantic groups of their
inputs/outputs instead of their op-encoding strategy, preserving these
groups will also facilitate partial transitions over to v8 Fast API for the
"min" and "bin" groups
This commit rewrites "JsRuntime::poll" function to fix a corner case that
might caused "overflown_response" to be overwritten by other overflown response.
The logic has been changed to allow returning multiple overflown response
alongside responses from shared queue.
This commit adds two new "Deno.core" APIs:
- "Deno.core.serialize"
- "Deno.core.deserialize"
These APIs are used to provide structured cloning of values
and will be used for further web worker implementation.

This commit refactors "deno_core::Modules" structure to not depend on
"get_identity_hash" function to identify modules, but instead use default
hash implementation.
Provides a concrete state type that can be dynamically added. This is necessary for op crates.
* renames BasicState to OpState
* async ops take `Rc<RefCell<OpState>>`
* sync ops take `&mut OpState`
* removes `OpRegistry`, `OpRouter` traits
* `get_error_class_fn` moved to OpState
* ResourceTable moved to OpState
deno_core/
- rename core_isolate.rs to runtime.rs
- rename CoreIsolate to JsRuntime
- rename JSError to JsError
- rename JSStackFrame to JsStackFrame
cli/
- update references from deno_core::CoreIsolate to deno_core::JsRuntime
- rename deno_core::JSError to deno_core::JsError
- rename fmt_errors::JSError to fmt_errors::JsError
This commit fixes problems with source maps in Chrome Devtools
by substituting source map URL generated by TS compiler with
actual file URL pointing to DENO_DIR.
Dummy value of "source_map_url" has been removed from
"ScriptOrigin".
Also fixes lock file which used compiled source code to generate
lock hash; it now uses source code of the file that is
being compiled.
* add tests for "Deno.core.encode" and "Deno.core.decode" for empty inputs
* use "Deno.core.encode" in "TextEncoder"
* use "Deno.core.decode" in "TextDecoder"
* remove "core_decode" and "core_encode" benchmarks
This commits add two new methods to "Deno.core" namespace: "encode" and "decode".
Those methods are bound in Rust to provide a) fast b) generally available of encoding and decoding UTF-8 strings.
Both methods are now used in "cli/js/dispatch_json.ts".
* remove Isolate.current_send_cb_info
* remove DenoBuf
* remove Isolate.shared_ab
* port Isolate.shared_response_buf (last bit not ported from libdeno)
* add some docs for Isolate and EsIsolate
* refactored RecursiveLoad - it was renamed to RecursiveModuleLoad, it does not take ownership of isolate anymore - a struct implementing Stream that yields SourceCodeInfo
* untangled module loading logic between RecursiveLoad and isolate - that logic is encapsulated in EsIsolate and RecursiveModuleLoad, where isolate just consumes modules as they become available - does not require to pass Arc<Mutex<Isolate>> around anymore
* removed EsIsolate.mods_ in favor of Modules and moved them inside EsIsolate
* EsIsolate now requires "loader" argument during construction - struct that implements Loader trait
* rewrite first methods on isolate as async
