Philippe Mathieu-Daudé f892b494fa scripts/tracetool: Update maintainer email address
There is an effort in progress to generate a QEMU Python
package. As I'm not sure this old email is still valid,
update it to not produce package with broken maintainer
email.

Patch created mechanically by running:

 $ sed -i 's,\(__email__ *= "\)stefanha@linux.vnet.ibm.com",\1stefanha@redhat.com",' \
         $(git grep -l 'email.*stefanha@linux.vnet.ibm.com')

Format management.
Creating new formats
--------------------
A new format named 'foo-bar' corresponds to Python module
'tracetool/format/foo_bar.py'.
A format module should provide a docstring, whose first non-empty line will be
considered its short description.
All formats must generate their contents through the 'tracetool.out' routine.
