Enable more linters, address the issues and do a major naming refactor
to use golang lower camelCase identifiers for types, functions, methods
and variable names.
Also:
* Clean up inline generation so it doesn't rely on temporary variables.
* Remove unused functions generated by inline.pl.
Enable the whitespace linter and fix the errors resulting from it.
Also:
* Remove unneeded golangci-lint config for disabled linters.
* Correct test number for panic in previous commit.
Leverage github actions for tests and linting.
This includes fixing a bunch of issues highlighted by golangci
including:
* Dead code.
* Ineffectual assigns.
* Goto warnings.
* Nil return err.
* Reused literal strings.
* Test parameter order.
Also:
* Setup clog.
* Streamline what we get from "otto/parser"
* Get rid of some "otto/parser" cruft
* FunctionExpression => FunctionLiteral
* The debugger statement (debugger) should do nothing (not panic)
* Fix aspects of function expression call evaluation
* Faster, more straightforward, etc.
* More advanced object literals (get ..., set ...)
* More tests using JavaScript from the wild (http://cdnjs.com/)
