Add the "stk500generic" programmer that auto-probes for STK500 

either firmware version 1 or 2.
* Makefile.am (avrdude_SOURCES): add the new files
stk500generic.c and stk500generic.h.
* avrdude.conf.in: Add the stk500generic programmer type, and
change the "stk500" entry to point to this programmer.
* config_gram.y: Add the stk500generic keyword.
* lexer.l: (Ditto.)
* stk500.c: Change the stk500v1 code to not call exit()
prematurely when failing to open the programmer, but instead
return an error status.
* stk500generic.c: (New file.) Stub programmer implementation.
Probe for either stk500v1 or stk500v2, and adjust the current pgm
appropriately.
* stk500generic.h: (New file.) Declare the public interface(s)
of stk500generic.c.
* doc/avrdude.texi: Document the changed behaviour of stk500.
