Remove tmpfile treatments

Madx.match does not return the results anymore.
Remove obsolete functions in _madx_tools
Remove file-name completion in Madx.call

Files should always be specified by their full name. Trying to guess a
different name should not be the responsibility of pymad.
Remove recursive_history feature

I don't believe the feature was very useful. It just added a
hard-to-understand parameter to the constructor of the Madx/Model
classes.

More importantly, the recursive_history mode, made it impossible to
distinguish between commands created by PyMAD and commands contained in
a CALLed file.
