main.c, pgm.c, pgm.h: Add setup and teardown hooks to the programmer

Browse Source 
definition.  If present, call the setup hook immediately after finding
the respective programmer object, and schedule the teardown hook to be
called upon exit.  This allows the programmer implementation to
dynamically allocate private programmer data.

avr910.c, butterfly.c, jtagmkI.c, jtagmkII.c, stk500v2.c, usbasp.c,
usbtiny.c: Convert static programmer data into dynamically allocated
data.
