Users can inherit from the simpletrace.Analyzer class and receive

signature is a little magic because the timestamp and pid arguments are

The ./configure script should produce --help output even if Python is
not installed.
Listing trace backends is simple: show the names of all Python modules
in scripts/tracetool/backend/ whose source code contains 'PUBLIC =
True'.
Perform the backend enumeration in shell instead of Python so that we
can move the Python check until after ./configure --help.
