[PATCH 0/5] MR5592: Rewrite of cmd.exe's command engine (part I)

[eric pouech (＠epo)]

This is the first serie of a major rewrite of cmd.exe's command engine
(lexer, parser, command handling).

The goal is to implement correctly:
- command chaining (&&, ||) operators,
- fix a number of issues (eg. 32679, 55401, 44063...)
- remove some spaghetti code from engine,
- allow to move forward on some pending MR (5246 5242 5194 4504...)

This first part mainly extends the tests with the issues
listed in above bug tickets & MR.
