/**
 * @brief Refreshes after permission changed or friending, etc.
 *
 * zot_refresh is typically invoked when somebody has changed permissions of a channel and they are notified
 * to fetch new permissions via a finger/discovery operation. This may result in a new connection
 * (abook entry) being added to a local channel and it may result in auto-permissions being granted.
 *
 * Friending in zot is accomplished by sending a refresh packet to a specific channel which indicates a
 * permission change has been made by the sender which affects the target channel. The hub controlling
 * the target channel does targetted discovery (a zot-finger request requesting permissions for the local
 * channel). These are decoded here, and if necessary and abook structure (addressbook) is created to store
 * the permissions assigned to this channel.
 *
 * Initially these abook structures are created with a 'pending' flag, so that no reverse permissions are
 * implied until this is approved by the owner channel. A channel can also auto-populate permissions in
 * return and send back a refresh packet of its own. This is used by forum and group communication channels
 * so that friending and membership in the channel's "club" is automatic.
 *
 * @param array $them => xchan structure of sender
 * @param array $channel => local channel structure of target recipient, required for "friending" operations
 * @param array $force default false
 *
 * @returns boolean true if successful, else false
