Rich Trott 87972cd76f buffer: remove "new" from deprecation message 
This change removes "new" as a description for `Buffer` construction
methods. They are arguably not "new" anymore and they certainly won't be
"new" anymore at some point.

Ruben Bridgewater c6b6c92185 lib: always show ERR_INVALID_ARG_TYPE received part 
This makes a effort to make sure all of these errors will actually
also show the received input.
On top of that it refactors a few tests for better maintainability.
It will also change the returned type to always be a simple typeof
instead of special handling null.

This adds a rule that forbids the use of native Error constructors in

Joyee Cheung 2a9eb316a1 src: move internal loaders out of bootstrap_node.js 
- Moves the creation of `process.binding()`, `process._linkedBinding()`
  `internalBinding()` and `NativeModule` into a separate file
  `lib/internal/bootstrap_loaders.js`, and documents them there.
  This file will be compiled and run before `bootstrap_node.js`, which
  means we now bootstrap the internal module & binding system before
  actually bootstrapping Node.js.
- Rename the special ID that can be used to require `NativeModule`
  as `internal/bootstrap_loaders` since it is setup there. Also put
  `internalBinding` in the object exported by `NativeModule.require`
  instead of putting it inside the `NativeModule.wrapper`
- Use the original `getBinding()` to get the source code of native
  modules instead of getting it from `process.binding('native')`
  so that users cannot fake native modules by modifying the binding
  object.
- Names the bootstrapping functions so their names show up
  in the stack trace.

Ruben Bridgewater e8bb1f35df buffer: refactor all read/write functions 
There are a lot of changes in this commit:

1) Remove the `noAssert` argument from all read and write functions.
2) Improve the performance of all read floating point functions
   significantly. This is done by switching to TypedArrays as the
   write floating point write functions.
3) No implicit type coercion for offset and byteLength anymore.
4) Adds a lot of tests.
5) Moves the read and write functions to the internal buffer file
   to split the files in smaller chunks.
6) Reworked a lot of existing tests.
7) Improve the performane of all all read write functions by using
   a faster input validation and by improving function logic.
8) Significantly improved the performance of all read int functions.
   This is done by using a implementation without a loop.
9) Improved error handling.
10) Rename test file to use the correct subsystem.

Zero-fill when `Buffer.alloc()` receives invalid fill data.

A solution like https://github.com/nodejs/node/pull/17427 which switches
to throwing makes sense, but is likely a breaking change.

This suggestion leaves the behaviour of `buffer.fill()` untouched,
since any change to it would be a breaking change, and lets
`Buffer.alloc()` check whether any filling took place or not.

Anatoli Papirovski fc1fa4e2c4 buffer: improve Buffer.from performance 
Using == null in code paths that are expected to mostly receive
objects, arrays or other more complex data types is not
ideal because typecasting these types is very slow. Change
to instead check === null || === undefined. Also move one
variable assignment in fromString after an if condition
that doesn't need it (and returns if truthy).

MAX_SAFE_INTEGER is millions of times larger than the largest buffer
allowed in Node.js. There is no need to squash the length down to
MAX_SAFE_INTEGER. Removing that check results in a small but
statistically significant increase for Buffer.from() operating on
ArrayBuffers in some situations.

Anna Henningsen d56a7e640f src: do proper StringBytes error handling 
- Return `MaybeLocal`s from `StringBytes::Encode`
- Add an `error` out parameter to pass JS exceptions to the callers
  (instead of directly throwing)
- Simplify some of the string generation methods in `string_bytes.cc`
  by unifying the `EXTERN_APEX` logic
- Reduce usage of deprecated V8 APIs.
- Remove error handling logic from JS, the `buffer.*Slice()` methods
  now throw errors themselves.
- Left TODO comments for future semver-major error message
  improvements.

This paves the way for better error messages coming out of the
StringBytes methods.
