MAX_HWM was added in 9208c89 where the highwatermark was changed to
always increase in steps of highest power of 2 to prevent increasing
hwm excessivly in tiny amounts.
Why a limit was added on the highwatermark is unclear but breaks
existing usage where a larger read size is used. The invariant for
read(n) is that a buffer of size n is always returned. Considering
a maximum ceiling on the buffer size breaks this invariant.
This PR significantly increases the limit to make it less likely to
break the previous invariant and also documents the limit.

Using `AtExit()` without an `Environment*` pointer or providing
an argument is almost always a sign of improperly relying on global
state and/or using `AtExit()` as an addon when the addon-targeting
`AddEnvironmentCleanupHook()` would be the better choice.
Deprecate those variants. This also updates the addon docs to
refer to `AddEnvironmentCleanupHook()` rather than `AtExit()`.

The use of dashes -- in general, but especially in our docs -- can be
problematic. It is used inconsistently and there is always another form
of punctuation that is as good or better for the situation. In an effort
to reduce the number of variations we use to display the same types of
information, remove the various uses of dashes from the documentation.

Adds the ability to `import` or `require` a package from within its
own source code. This allows tests and examples to be written using
the package name, making them easier to reuse by consumers of the
package.
Assuming the `name` field in `package.json` is set to `my-pkg`, its
test could use `require('my-pkg')` or `import 'my-pkg'` even if
there's no `node_modules/my-pkg` while testing the package itself.
An important difference between this and relative specifiers like
`require('../')` is that self-references use the public interface
of the package as defined in the `exports` field while relative
specifiers don't.
This behavior is guarded by a new experimental flag
(`--experimental-resolve-self`).

Notable changes:
* assert:
* If the validation function passed to `assert.throws()` or
`assert.rejects()` returns a value other than `true`, an assertion
error will be thrown instead of the original error to highlight the
programming mistake (Ruben Bridgewater).
https://github.com/nodejs/node/pull/28263
* If a constructor function is passed to validate the instance of
errors thrown in `assert.throws()` or `assert.reject()`, an
assertion error will be thrown instead of the original error
(Ruben Bridgewater).
https://github.com/nodejs/node/pull/28263
* build:
* Node.js releases are now built with default full-icu support. This
means that all locales supported by ICU are now included and
Intl-related APIs may return different values than before
(Richard Lau).
https://github.com/nodejs/node/pull/29887
* The minimum Xcode version supported for macOS was increased to 10.
It is still possible to build Node.js with Xcode 8 but this may no
longer be the case in a future v13.x release (Michael Dawson).
https://github.com/nodejs/node/pull/29622
* child_process:
* `ChildProcess._channel` (DEP0129) is now a Runtime deprecation
(cjihrig).
https://github.com/nodejs/node/pull/27949
* console:
* The output `console.timeEnd()` and `console.timeLog()` will now
automatically select a suitable time unit instead of always using
milliseconds (Xavier Stouder).
https://github.com/nodejs/node/pull/29251
* deps:
* The V8 engine was updated to version 7.8. This includes performance
improvements to object destructuring, memory usage and WebAssembly
startup time (Myles Borins).
https://github.com/nodejs/node/pull/29694)
* domain:
* The domain's error handler is now executed with the active domain
set to the domain's parent to prevent inner recursion
(Julien Gilli).
https://github.com/nodejs/node/pull/26211
* fs:
* The undocumented method `FSWatcher.prototype.start()` was removed
(Lucas Holmquist).
https://github.com/nodejs/node/pull/29905
* Calling the `open()` method on a `ReadStream` or `WriteStream` now
emits a runtime deprecation warning. The methods are supposed to be
internal and should not be called by user code (Robert Nagy).
https://github.com/nodejs/node/pull/29061
* `fs.read/write`, `fs.readSync/writeSync` and `fd.read/write` now
accept any safe integer as their `offset` parameter. The value of
`offset` is also no longer coerced, so a valid type must be passed
to the functions (Zach Bjornson).
https://github.com/nodejs/node/pull/26572
* http:
* Aborted requests no longer emit the `end` or `error` events after
`aborted` (Robert Nagy).
https://github.com/nodejs/node/pull/27984https://github.com/nodejs/node/pull/20077
* Data will no longer be emitted after a socket error (Robert Nagy).
https://github.com/nodejs/node/pull/28711
* The legacy HTTP parser (previously available under the
`--http-parser=legacy` flag) was removed (Anna Henningsen).
https://github.com/nodejs/node/pull/29589
* The `host` option for HTTP requests is now validated to be a string
value (Giorgos Ntemiris).
https://github.com/nodejs/node/pull/29568
* The `request.connection` and `response.connection` properties are now
runtime deprecated. The equivalent `request.socket` and `response.socket`
should be used instead (Robert Nagy).
https://github.com/nodejs/node/pull/29015
* http, http2:
* The default server timeout was removed (Ali Ijaz Sheikh).
https://github.com/nodejs/node/pull/27558

changed from "Unordered Collection" to "Too Early" (Sergei Osipov).
https://github.com/nodejs/node/pull/29880

* The `error.errno` property will now always be a number. To get the
string value, use `error.code` instead (Joyee Cheung).
https://github.com/nodejs/node/pull/28140
* module:
* `module.createRequireFromPath()` is deprecated. Use
`module.createRequire()` instead (cjihrig).
https://github.com/nodejs/node/pull/27951
* src:
* Changing the value of `process.env.TZ` will now clear the tz cache.
This affects the default time zone used by methods such as
`Date.prototype.toString` (Ben Noordhuis).
https://github.com/nodejs/node/pull/20026

* The timing and behavior of streams was consolidated for a number of
edge cases. Please look at the individual commits below for more
information.

Add a flag that makes Node.js print the stack trace at the
time of *throwing* uncaught exceptions, rather than at the
creation of the `Error` object, if there is any.
This is disabled by default because it affects GC behavior.
