* Remove needless RegExp flag
In fixed case, `/g` flag is needless in the boolean context.
* Remove needless RegExp capturing
Use non-capturing grouping or remove capturing completely when:
* capturing is useless per se, e.g. in test() check;
* captured groups are not used afterward at all;
* some of the later captured groups are not used afterward.
* Use test, not match/exec in boolean context
match() and exec() return a complicated object,
unneeded in a boolean context.
* Do not needlessly repeat RegExp creation
This commit takes RegExp creation out of cycles and other repetitions.
As long as the RegExp does not use /g flag and match indices,
we are safe here.
In tests, this fix hardly gives a significant performance gain,
but it increases clarity and maintainability,
reassuring some RegExps to be identical.
RegExp in functions are not taken out of their functions:
while these functions are called many times
and their RegExps are recreated with each call,
the performance gain in test cases
does not seem to be worth decreasing function self-dependency.

Updates the fs module APIs to allow 'file://' URL objects
to be passed as the path.
For example:
```js
const URL = require('url').URL;
const myURL = new URL('file:///C:/path/to/file');
fs.readFile(myURL, (err, data) => {});
```
On Windows, file: URLs with a hostname convert to UNC paths,
while file: URLs with drive letters convert to local absolute
paths:
```
file://hostname/a/b/c => \\hostname\a\b\c
file:///c:/a/b/c => c:\a\b\c
```
On all other platforms, file: URLs with a hostname are unsupported
and will result in a throw:
```
file://hostname/a/b/c => throw!
file:///a/b/c => /a/b/c
```
The documentation for the fs API is intentionally not updated in
this commit because the URL API is still considered experimental
and is not officially documented *at this time*
Note that file: URLs are *required* by spec to always be absolute
paths from the file system root.
This is a semver-major commit because it changes error handling
on the fs APIs.

Currently there are many instances where assert.fail is directly passed
to a callback for error handling. Unfortunately this will swallow the
error as it is the third argument of assert.fail that sets the message
not the first.
This commit adds a new function to test/common.js that simply wraps
assert.fail and calls it with the provided message.
Tip of the hat to @trott for pointing me in the direction of this.

Enable linting for the test directory. A number of changes was made so
all tests conform the current rules used by lib and src directories. The
only exception for tests is that unreachable (dead) code is allowed.
test-fs-non-number-arguments-throw had to be excluded from the changes
because of a weird issue on Windows CI.

Currently, nullCheck() will attempt to invoke any truthy value
as a function if the path argument contains a null character.
This commit validates that the callback is actually a function
before trying to invoke it. fs.access() was vulnerable to this
bug, as nullCheck() was called prior to type checking its
callback.
