[Gpsbabel-code] Real-time tracking mode does not clean up on CTRL-C?

[Ture P. <tur...@gm...>]

(Hardware: Garmin eTrex Vista HCx, Intel-based Mac; Software: gpsbabel
1.4.2, MacOS 10.6)

If I run gpsbabel in the "-T" mode, stop it with CTRL-C, and then
start it again, it reports an error (see below) and the GPS device
turns itself off. It seems like protocol state does not get properly
cleaned up on CTRL-C. The enclosed quick-and-dirty patch solves the
problem for me, though I have no idea whether it is The Right Thing.
It does two things: 1) change a 'fatal' to a plain printf to keep the
program from exiting before the clean-up code is executed and 2)
actually write some clean-up code. :-)
