Log Message:
snprintb: error out on out-of-bounds bit shifts

Previously, these invoked undefined behavior, now they lead to an early
return. An example of out-of-bounds bit number is in SCZ_PCICTRL_BITS.
Bit fields that extend beyond the msb are still allowed.

Allow 'f' and 'F' to have fields that are 64 bits wide. This only makes
sense when the field starts at bit 0.

Remove the unused 'val_len', it was only needed before snprintb.c 1.20.
