Fixed in r983.

Calling exit(0) from deep within the callstack has been
proven fatal (and was a big DON'T in the light of this being
within a library function).  The exithook handler called
stk500v2_jtagmkII_teardown() which in turn tried to switch
the private data context for the call to jtagmkII_teardown() -
but the context was still set up for jtagmkII mode anyway,
as this was the case when executing jtagmkII_getsync().

Avrdude did segfault when running the second time after after programming the DWEN fuse.
The dragon had to be reset (power cycled) to work properly afterwards, too.
