Package-level declarations

Message friendchannel is used to transmit messages within a friend chat channel.

Update friendchat channel full V1 is used to send full channel updates where the list of entries has a size of 255 or less, as that is the maximum theoretical limitation.

Update friendchat channel full V2 is used to send full channel updates where the list of entries has a size of more than 255. It can also support sizes below that, but for sizes in range of 128..255, it is more efficient by 1 byte to use V1 of this packet.

Update friendchat singleuser is used to perform a change to a friend chat for a single user, whether that be adding the user to the friend chat, or removing them.
