This commit renames occurrences of "isolate" variable name
to "js_runtime". This was outstanding debt after renaming
deno_core::CoreIsolate to JsRuntime.
This commit adds support for stack traces in "deno_core".
Implementation of "Display" trait for "JsError" has been updated
and in consequence "deno_core::js_check" became obsolete and
removed.
Removes:
- "deno_core::StartupData"
- "deno_core::Script"
- "deno_core::OwnedScript"
Changes to "JsRuntime":
- remove "new_with_loader()"
- remove "with_heap_limits()"
- rename "IsolateOptions" to "RuntimeOptions" and make public
- "JsRuntime::new()" takes "RuntimeOptions" as a single param
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
