Fix a few warnings that came up recently (some of them only triggered 

by recent GCC versions).
* config_gram.y (parse_cmdbits): "brkt possibly used uninitialized"
(GCC errs here)
* jtagmkII.c (jtagmkII_reset32): "status possibly used uninitialized"
(I think GCC errs, too)
* buspirate.c: "pointers differ in signedness" (mismatch between
string processing and the use of "unsigned char" throughought the
AVRDUDE API)
