Subject: tracetool: remove dead code

Remove a bunch of dead code from tracetool.

In particular, there are no tcg-exec events anymore and the sub-event
functionality was only used for it.

Subject: treewide: remove unnessary "coding" header

The "-*- coding: utf-8 -*-" header was needed in Python 2,
but in Python 3 UTF-8 is already the default encoding of
source files.

It is even less necessary in .css files that do not have UTF-8
sequences at all.
