The term "native module" dates back to some of the oldest code
in the code base. Within the context of Node.js core it usually
refers to modules that are native to Node.js (e.g. fs, http),
but it can cause confusion for people who don't work on this
part of the code base, as "native module" can also refer to
native addons - which is even the case in some of the API
docs and error messages.
This patch tries to make the usage of these terms more consistent.
Now within the context of Node.js core:
- JavaScript scripts that are built-in to Node.js are now referred
to as "built-in(s)". If they are available as modules,
they can also be referred to as "built-in module(s)".
- Dynamically-linked shared objects that are loaded into
the Node.js processes are referred to as "addons".
We will try to avoid using the term "native modules" because it could
be ambiguous.
Changes in this patch:
File names:
- node_native_module.h -> node_builtins.h,
- node_native_module.cc -> node_builtins.cc
C++ binding names:
- `native_module` -> `builtins`
`node::Environment`:
- `native_modules_without_cache` -> `builtins_without_cache`
- `native_modules_with_cache` -> `builtins_with_cache`
- `native_modules_in_snapshot` -> `builtins_in_cache`
- `native_module_require` -> `builtin_module_require`
`node::EnvSerializeInfo`:
- `native_modules` -> `builtins
`node::native_module::NativeModuleLoader`:
- `native_module` namespace -> `builtins` namespace
- `NativeModuleLoader` -> `BuiltinLoader`
- `NativeModuleRecordMap` -> `BuiltinSourceMap`
- `NativeModuleCacheMap` -> `BuiltinCodeCacheMap`
- `ModuleIds` -> `BuiltinIds`
- `ModuleCategories` -> `BuiltinCategories`
- `LoadBuiltinModuleSource` -> `LoadBuiltinSource`
`loader.js`:
- `NativeModule` -> `BuiltinModule` (the `NativeModule` name used in
`process.moduleLoadList` is kept for compatibility)
And other clarifications in the documentation and comments.

There is no reason to hide FIPS functionality behind build flags.
OpenSSL always provide the information about FIPS availability via
`FIPS_mode()` function.
This makes the user experience more consistent, because the OpenSSL
library is always queried and the `crypto.getFips()` always returns
OpenSSL settings.

The `setup()` method is only called when the `--experimental-report`

Remove the following properties:
- `preserveSymlinks`
- `preserveSymlinksMain`
- `experimentalModules`
- `userLoader`
- `experimentalVMModules`
- `experimentalREPLAwait`
- `exposeInternals`
We used to use them to pass cli option values from C++ into
JS, but now the values are obtained in JS land using
`require('internal/options').getOptionValue` instead so they
are unused.
Also removes `test/parallel/test-internal-modules-expose.js`
which tests `--expose-internals`.
We already have hundreds of tests depending on `--expose-internals`,
they are more than enough to test the functionality of the flag.

Having an experimental feature behind a flag makes change
if we are expecting significant breaking changes to its API.
Since the Worker API has been essentially stable since
its initial introduction, and no noticeable doubt about
possibly not keeping the feature around has been voiced,
removing the flag and thereby reducing the barrier to experimentation,
and consequently receiving feedback on the implementation,
seems like a good idea.

So that it's easier to tell whether we are manipulating per-process

Also added comments about these variables and moved some of them
to a more suitable compilation unit:
- Move `v8_initialized` to `util.h` since it's only used in
`util.cc` and `node.cc`
- Rename `process_mutex` to `tty_mutex` and move it into
`node_errors.cc` since that's the only place it's used
to guard the tty.
- Move `per_process_opts_mutex` and `per_process_opts`
into `node_options.h` and rename them to
`per_process::cli_options[_mutex]`
- Rename `node_isolate[_mutex]` to `per_process::main_isolate[_mutex]`

Instead of using a shared pointer of the entire debug option set,
pass the parsed debug option to inspector classes by value because
they are set once the CLI argument parsing is done. Add another shared
pointer to HostPort being used by the inspector server, which is copied
from the one in the debug options initially. The port of the shared
HostPort is 9229 by default and can be specified as 0 initially but
will be set to the actual port of the server once it starts listening.
This makes the shared state clearer and makes it possible to use
`require('internal/options')` in JS land to query the CLI options
instead of using `process._breakFirstLine` and other underscored
properties of `process` since we are now certain that these
values should not be altered once the parsing is done and can be
passed around in copies without locks.

This is a major refactor of our Node’s parser. See `node_options.cc`
for how it is used, and `node_options-inl.h` for the bulk
of its implementation.
Unfortunately, the implementation has come to have some
complexity, in order to meet the following goals:
- Make it easy to *use* for defining or changing options.
- Keep it (mostly) backwards-compatible.
- No tests were harmed as part of this commit.
- Be as consistent as possible.
- In particular, options can now generally accept arguments
through both `--foo=bar` notation and `--foo bar` notation.
We were previously very inconsistent on this point.
- Separate into different levels of scope, namely
per-process (global), per-Isolate and per-Environment
(+ debug options).
- Allow programmatic accessibility in the future.
- This includes a possible expansion for `--help` output.
This commit also leaves a number of `TODO` comments, mostly for
improving consistency even more (possibly with having to modify
tests), improving embedder support, as well as removing pieces of
exposed configuration variables that should never have become
part of the public API but unfortunately are at this point.

Removes the requirement to use `--trace-events-enabled` to enable
trace events. Tracing is enabled automatically if there are any
enabled categories.
Adds a new `trace_events` module with an API for enabling/disabling
trace events at runtime without a command line flag.
```js
const trace_events = require('trace_events');
const categories = [ 'node.perf', 'node.async_hooks' ];
const tracing = trace_events.createTracing({ categories });
tracing.enable();
// do stuff
tracing.disable();
```
Multiple `Tracing` objects may exist and be enabled at any point
in time. The enabled trace event categories is the union of all
enabled `Tracing` objects and the `--trace-event-categories`
flag.
