  1. src: avoid returning invalid value from hex2bin 

    If the input is not a valid hexadecimal digit, hex2bin should not return
an invalid value, which is not handled correctly by the caller, which is
the PercentDecode function. However, PercentDecode only ever calls the
hex2bin function with valid hexadecimal digits, so mark the code path
that previously returned an invalid value for non-digits as UNREACHABLE.
