Converts a hex string into an int. Integer.parseInt(hex, 16) assumes the input is nonnegative unless there is a preceding minus sign. This method reads the input as twos complement instead, so if the input is 8 bytes long, it will correctly restore a negative int produced by Integer.toHexString() but not neccesarily one produced by Integer.toString(x,16) since that method will produce a string like '-FF' for negative integer values.

if the string is more than 16 characters long, or if any character is not in the set [0-9a-fA-f]
