This commit adds support for running test in parallel.
Entire test runner functionality has been rewritten
from JavaScript to Rust and a set of ops was added to support reporting in Rust.
A new "--jobs" flag was added to "deno test" that allows to configure
how many threads will be used. When given no value it defaults to 2.
This commits adds adds "permissions" option to the test definitions
which allows tests to run with different permission sets than
the process's permission.
The change will only be in effect within the test function, once the
test has completed the original process permission set is restored.
Test permissions cannot exceed the process's permission.
You can only narrow or drop permissions, failure to acquire a
permission results in an error being thrown and the test case will fail.
This commit changes formatting of JS errors; by not showing
source lines for internal code. Where possible, instead using
the top stack frame associated with user code i.e. the first
location that is colourful and not a "deno:" URL.
This commit adds support for loading import maps from URLs,
both remote and local.
This feature is supported in CLI flag as well as in runtime
compiler API.
This commit moves Deno JS runtime, ops, permissions and
inspector implementation to new "deno_runtime" crate located
in "runtime/" directory.
Details in "runtime/README.md".

This commit does major refactor of "Worker" and "WebWorker",
in order to decouple them from "ProgramState" and "Flags".
The main points of interest are "create_main_worker()" and
"create_web_worker_callback()" functions which are responsible
for creating "Worker" and "WebWorker" in CLI context.
As a result it is now possible to factor out common "runtime"
functionality into a separate crate.
This commit disables source mapping of errors
for standalone binaries. Since applying source
maps relies on using file fetcher infrastructure
it's not feasible to use it for standalone binaries
that are not supposed to use that infrastructure.
Factored out "init_v8_flags", "init_logger" and
"get_subcommand" from "main" function.
Also "Worker" was removed in favor of moving
logic to "MainWorker" and "WebWorker" respectively.
This commit simplifies code responsible for serialization
of web worker events. Instead of using "PrettyJsError"
it's enough to downcast to "deno_core::JsError", making
the code less specific to cli/ implementation.
This commit renames "fmt_errors::JsError" to "PrettyJsError"
to avoid confusion with "deno_core::JsError".
Consequently "CoreJsError" aliases to "deno_core::JsError"
were removed.
Additionally source mapping step has been removed from
"PrettyJsError::create" to better separate domains.
This commit renames "fs" module in "cli/" to "fs_util". This is purely
cosmetic change; there were a few places which aliased "crate::fs"
to "deno_fs" which was very confusing with "fs" module in ops.
This commit changes implementation of top-level-await in "deno_core".
Previously promise returned from module evaluation was not awaited,
leading to out-of-order execution of modules that have TLA. It's been
fixed by changing "JsRuntime::mod_evaluate" to be an async function
that resolves when the promise returned from module evaluation also
resolves. When waiting for promise resolution event loop is polled
repeatedly, until there are no more dynamic imports or pending
ops.
