Change the subsystem-group and manager code to use shared-ptr references
to subsystems, instead of holding a raw pointer. Hence the manager becomes
the owning ref to most subsystems.
Allow subsystem init to be incremental, i.e requiring repeated init calls until a 'done' code is returned. Use this to support incremental init in groups and the manager. (It would also be possible to support it in an individual subsystem).
Note that if you use the existing init() calls, behaviour is unchanged.
Adapt the freealut code into a WAV-file reader. As a side-effect, it would now be possible to deploy WAV files compressed with gzip, since we use ZLib's gzread functions to read from disk.
Have a more general timestamp implementation.
Very useful for higher accuracy timings.

- Added a SampleStatistic class (from the old deprecated libg++) library.
- Make time statistics and printing conditionable
- Added an interface function to switch time stamp collection and printing
on and off from the application (defaults to off).
- don't unlock an already unlocked mutex (Someone wanted to be on
the safe side with this, but the result is undefined and makes
pthread_mutex_destroy fail. Reference: manpage for
pthread_mutexattr_gettype/The Open Group[1]: "Attempting to
unlock a mutex of this type which is not locked results in
undefined behaviour.")
- re-enabled all subsystem destructors again (this has been disabled
because fgfs hung on exit, due to the mutex destroy failure from
above.)

- new FSF address
- removed a few hundred trailing spaces
- fixed a few $Id$ lines
- copied two license headers from *.hxx files to their respective
*.cxx counterparts
- added two test aps to .cvsignore

This is the more elegant solution that Andy had proposed in a response
to my RFC on Nasal initialization code in joystick configuration files.
As Nasal is initialized last (for good reason), subsystem can currently
not use it for initializing. postinit() is called on all subsystems
after all have been initialized.
