Ben Noordhuis df30fd586d buffer: optimize readDouble and readFloat methods
Compute the floating point number in JavaScript to avoid having to call
out to the C++ runtime.  The improvements are not insubstantial:

cjihrig cd174df353 buffer: throw on failed fill attempts
If fill() attempts to write a string to a buffer, but fails
silently, then uninitialized memory could be leaked. This commit
causes fill() to throw if the string write operation fails.

Anna Henningsen 69a68c0b24 buffer: zero-fill buffer allocated with invalid content
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).

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.

Rich Trott 096508dfa9 tools,lib: enable strict equality lint rule
Enablie a lint rule to require `===` and `!==` instead of `==` and `!=`
except in some well-defined cases:

* comparing against `null` as a shorthand for also checking for
  `undefined`
* comparing the result of `typeof`
* comparing literal values

In cases where `==` or `!=` are being used as optimizations, use an
ESLint comment to disable the `eqeqeq` rule for that line explicitly. I
rather like this because it's a signal that the usage is intentional and
not a mistake.

alejandro 51587b2202 buffer: preallocate array with buffer length
Because the final array length is known, it's better to allocate its
final length at initialization time to avoid future reallocations.

Also add an explicit buffer length greater than 0 comparison so
it's more readable, avoids the internal ToBoolean call and follows the
standard Node.js API format (as it can be checked in other similar
structures where 'length > 0' is preferred over 'length')

Rich Trott 39bba4dff8 buffer: remove unneeded eslint-disable comment
lib/buffer.js uses a function declaration for `Buffer`. So it never
uses an instance of `Buffer` in the global scope. Therefore the
disabling of the `require-buffer` custom rule is not needed. Remove the
comment.

up to 11% performance gains when allocating any kind of Buffer.

Avoid avoids use of in, resulting in ~50% improvement when creating
a Buffer from an array-like object.
