Subject: [PATCH 00/22] tty: vt: cleanup ESC sequences handling

This is a promised followup of "tty: vt: cleanup and documentation" [1].

The escape sequences parser is cleaned up, so that it is easier to
follow.

Most of the patches are easier to review with '-w -b' passed to git diff
(as the code is moved to separate functions with a different level of
indentation only).
