28efa4fe95 lib: delay access to CLI option to pre-execution
CLI options should not be added through the config binding, instead
they are already available in the JS land via
`require('internal/options')`. Also CLI options in principle should
be processed in pre-execution instead of bootstrap scripts.

lib: flatten access to primordials
Store all primordials as properties of the primordials object.
Static functions are prefixed by the constructor's name and prototype
methods are prefixed by the constructor's name followed by "Prototype".
For example: primordials.Object.keys becomes primordials.ObjectKeys.

module: reduce circular dependency of internal/modules/cjs/loader
Previously `internal/bootstrap/pre_execution.js` requires
`internal/modules/cjs/loader.js` which in turn requires
`internal/bootstrap/pre_execution.js`. This patch moves the
entry point execution logic out of `pre_execution.js` and
puts it into `internal/modules/run_main.js`. It also tests
that `Module.runMain` can be monkey-patched before further
deprecation/refactoring can be done.

Also added an internal assertion `hasLoadedAnyUserCJSModule`
for documentation purposes.

src: refactor uncaught exception handling
The C++ land `node::FatalException()` is not in fact fatal anymore.
It gives the user a chance to handle the uncaught exception
globally by listening to the `uncaughtException` event. This patch
renames it to `TriggerUncaughtException` in C++ to avoid the confusion.

In addition rename the JS land handler to `onGlobalUncaughtException`
to reflect its purpose - we have to keep the alias
`process._fatalException` and use that for now since it has been
monkey-patchable in the user land.

This patch also

- Adds more comments to the global uncaught exception handling routine
- Puts a few other C++ error handling functions into the `errors`
  namespace
- Moves error-handling-related bindings to the `errors` binding.

util: access process states lazily in debuglog
`debuglog()` depends on `process.pid` and `process.env.NODE_DEBUG`,
so it needs to be called lazily in top scopes of internal modules
that may be loaded before these run time states are allowed to
be accessed. This patch makes its implementation lazy by default,
the process states are only accessed when the returned debug
function is called for the first time.

process: add --unhandled-rejections flag
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.

src: do not call into JS in the maxAsyncCallStackDepthChanged interrupt
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.

lib: explicitly initialize debuglog during bootstrap
This patch splits the implementation of util.debuglog into a
separate file and explicitly initialize it during pre-execution

Also delays the call to `debuglog` in modules that are loaded during

during pre-execution.

process: move initialization of node-report into pre_execution.js
- 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.

src: move async hooks trace events setup to pre_execution.js
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.

process: split execution into main scripts
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.
