Use uint8_t for HardwareSerial ringbuffer pointers
Since the buffers aren't bigger than 64 bytes, these values can be
smaller. This saves a few bytes of ram, but also saves around 50 bytes
of program space, since the values can now be loaded using a single
instruction.
To prevent problems when people manually increase the buffer size, a
compile-time check is added.
Closes: #1078
