Public bug reported:

This bug was found while examining the source code of libdc1394 version
2.2.0 so OS version is irrelevant.

The API states that ISO resources associated with a camera are freed
when the camera is freed by default unless they are explicitly set to
persist beyond the lifetime of a camera.  For both cases, the opposite
of the desired behaviour occurs.

This behaviour is controlled by a private variable, iso_persist.  The
variable is initialised to zero.  The only place it is modified is by
dc1394_iso_set_persist(camera) where it is set to 1.

When a camera is freed via dc1394_camera_free(camera), a conditional
expression determines whether or not the iso resources are released.  It
frees the iso resources if iso_persist is nonzero and does not free
resources if iso_persist is 0.  This is the opposite of the desired
behaviour given that by default iso_persist is 0.
