Relax the rule for maximum line length in JS files if the line contains
a regular expression literal. This will avoid the need to convert a
regular expression literal into a RegExp constructor call broken across
multiple lines in order to satisfy the maximum line length rule. That
practice hampers readability.

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.

The second argument to "assert.throws" is usually a validation RegExp or
function for the thrown error. However, the function also accepts a
string and in this case it is interpreted as a message for the
AssertionError and not used for validation. It is common for people to
forget this and pass a validation string by mistake.
This new rule checks that we never pass a string literal as a second argument
to "assert.throws". Additionally, there is an option to enforce the
function to be called with at least two arguments. It is currently off
because we have many tests that do not comply with this rule.

There has been occasional nits for spacing in object literals in PRs but
the project does not lint for it and it is not always handled
consistently in the existing code, even on adjacent lines of a file.
This change enables a linting rule requiring no space between the key
and the colon, and requiring at least one space (but allowing for more
so property values can be lined up if desired) between the colon and the
value. This appears to be the most common style used in the current code
base.
Example code the complies with lint rule:
myObj = { foo: 'bar' };
Examples that do not comply with the lint rule:
myObj = { foo : 'bar' };
myObj = { foo:'bar' };
