be needed, but it at least works right now).
- Improved the transmission of 32-bit negative numbers on systems
where the 32-bit type is larger than 32 bits.
- Changed the sending of 64-bit numbers for protocol 30: we send
them in MSB-first order with the number of bytes used in the
transmission encoded into the earliest bits. This lets us save
transmitted bytes for both small and large numbers. The new
method sends from 3 to 9 bytes, the old sent either 4 or 12.
