Fix deprecated method Buffer.new

Introduce parameter object for API params that travel together

Previously, most tests were using https://github.com and only the first was using https://github.example.com. As it happens, https://github.com works for all of them.

Make sure a Python 2 pip is installed

In the README of this repo, it's suggested to use the `ubuntu-latest` environment.
That environment will soon be upgraded to Ubuntu 20.04: https://github.com/actions/virtual-environments/issues/1816

As pointed out in that issue, the updated image comes without a Python 2 pip preinstalled:

    Setup Python dependencies
    /home/runner/work/_actions/github/codeql-action/v1/python-setup/install_tools.sh
    [...]
      + python2 -m pip install --user --upgrade pip setuptools wheel
      /usr/bin/python2: No module named pip
    Warning: Unable to download and extract the tools needed for installing the python dependecies. You can call this action with 'setup-python-dependencies: false' to disable this process.

Add a query to detect binary planting vulnerabilities.

Fix typos in source code, logging, comments, and config files

Update code so "no-shadow" passes

Skip Runner integration tests on pull requests from forks.

Two minor code fixes

Abort CodeQL action if the status cannot be reported

Fix a minor issue in the update-release-branch.py script that performs a
call to `sorted` but doesn't use the output. Since `sorted` does not
operate in place, the call is currently useless. As a result, the function
`get_pr_for_commit` does not currently work as exected. I.e. it is
expected to return the "first" (i.e. lowest PR number), but actually it
returns the first in the list provided by GitHub.

The tracer-config.test.js file contained a duplicate of the statement:

  process.env["SEMMLE_DEPTRACE_SOCKET"] = "abc";

one line apart. This removes the second instance of this statement.

- Rename "toolrunnner" (three 'n') to "toolrunner"
- Rename "relativeFilepaht" to "relativeFilepath"
- Fix various typos in documentation & comments
- Fix typos in logs and test names

Rename one instance of "path"  to avoid shadowing.
