Subject: rework Process API & tests

* Add separate classes ProcessParameters & ShellParameters for
Process::create() and Process::shell() methods.
* Add a separate "worker" executable. It's used in tests via a fairly
complicated scheme, receiving orders to execute via a shared memory
region.
* Add tests that utilize the Console API, reading console window's
screen buffer directly, making for more reliable tests & broader
coverage.
