Summary0003463: Tweak "futures" bitfiled for channel ACKs
DescriptionThe "futures" field indicates all messasges received after the one indicated in the "ack" field.

Right now it enumerates messages in direct following order. Bit 0 is ack+1, bit 1 is ack+2 ... bit 63 is ack+64.

Since ack indicates the furthest contiguous message received, ack+1 will NEVER be set, it is implicit in ack that ack+1 is missing.

The futures field should be changed to bit 0 is ack+2 and bit 63 is ack+65.

WARNING: This breaks protocol retro-compatibility.
TagsNo tags attached.

ACK+1 will be set if receiving client is slow processing incoming traffic, the receiving service's buffer is full and the sender should slow down.
