This improves the worker coverage by using `internal/assert` instead
of relying on `assert` in case a faulty worker message type is
received.

This adds a flag to define the default behavior for unhandled
rejections. Three modes exist: `none`, `warn` and `strict`. The first
is going to silence all unhandled rejection warnings. The second
behaves identical to the current default with the excetion that no
deprecation warning will be printed and the last is going to throw
an error for each unhandled rejection, just as regular exceptions do.
It is possible to intercept those with the `uncaughtException` hook
as with all other exceptions as well.
This PR has no influence on the existing `unhandledRejection` hook.
If that is used, it will continue to function as before.

If Debugger.setAsyncCallStackDepth is sent during bootstrap,
we cannot immediately call into JS to enable the hooks, which could
interrupt the JS execution of bootstrap. So instead we save the
notification in the inspector agent if it's sent in the middle of
bootstrap, and process the notification later here.

This patch splits the implementation of util.debuglog into a
separate file and explicitly initialize it during pre-execution
since the initialization depends on environment variables.
Also delays the call to `debuglog` in modules that are loaded during
bootstrap to make sure we only access the environment variable
during pre-execution.

- Splits signal handler setup code into two functions: one sets up
`process.on('SIGNAL_NAME')`, another takes care of the signal
triggers of node-report. Both should only happen on the main thread.
The latter needs to happen after the node-report configurations
are read into the process.
- Move the initialization of node-report into pre_execution.js
because it depends on CLI/environment settings.

Reasons:
- Moves more environment-dependent setup out of bootstrap/node.js
- No async operations should be done before the call to
the setup functions in pre_execution.js so no async hooks should be
triggered before that. Therefore it is safe to delay the setup
until then.

This patch groups the preparation of main thread execution into
`prepareMainThreadExecution()` and removes the cluster IPC
setup in worker thread bootstrap since clusters do not use
worker threads for its implementation and it's unlikely to change.

This patch directly inlines `createMessageHandler()` and
`createWorkerFatalExeception()` in the new

of the two methods are related to the execution flow of

This patch splits the execution mode selection from the environment
setup in `lib/internal/bootstrap/node.js`, and split the entry point
of different execution mode into main scripts under
`lib/internal/main`:
- `check_syntax.js`: used when `-c`/`--check` which only checks the
syntax of the input instead of executing it.
- `eval_stdin.js`: used when `-e` is passed without value and stdin
is not a TTY (e.g. something is piped).
- `eval_string`: used when `-e` is passed along with a string argument
- `inspect.js`: for `node inspect`/`node debug`
- `print_bash_completion.js`: for `--completion-bash`
- `print_help.js`: for `--help`
- `prof_process.js`: for `--prof-process`
- `repl.js`: for the REPL
- `run_main_module.js`: used when a main module is passed
- `run_third_party_main.js`: for the legacy `_third_party_main.js`
support
- `worker_thread.js`: for workers
This makes the entry points easier to navigate and paves the way
for customized v8 snapshots (that do not need to deserialize
execution mode setup) and better embedder APIs.
As an example, after this patch, for the most common case where
Node.js executes a user module as an entry point, it essentially
goes through:
- `lib/internal/per_context.js` to setup the v8 Context (which is
also run when setting up contexts for the `vm` module)
- `lib/internal/bootstrap/loaders.js` to set up internal binding
and builtin module loaders (that are separate from the loaders
accessible in the user land).
- `lib/internal/bootstrap/node.js`: to set up the rest of the
environment, including various globals and the process object
- `lib/internal/main/run_main_module.js`: which is selected from
C++ to prepare execution of the user module.
This patch also removes `NativeModuleLoader::CompileAndCall` and
exposes `NativeModuleLoader::LookupAndCompile` directly so that
we can handle syntax errors and runtime errors of bootstrap
scripts differently.
