net.server_epoll: Improve efficiency of sending much buffered data Problem: The string slice operations when a lot of data gets buffered ends up being expensive and memory-consuming. We have util.dbuffer for precisely this kind of thing. I want to keep the behavior of writebuffer being upgraded from nil to a string to full buffer since the last step involves three table allocations, where the previous buffer method only used one. Avoiding those allocations for simple writes like white space keep alive feels like it would keep memory churn down. This work was started in 2020

This file documents the structure of the roster object.

table roster {
  [string bare_jid] = roster_item
}

table roster_item {
  string subscription = "none" | "to" | "from" | "both"
  string name = Opaque string set by client. (optional)
  set groups = a set of opaque strings set by the client
  boolean ask = nil | "subscribe" - a value of true indicates subscription is pending
}

The roster is available as
 hosts[host].sessions[username].roster
and a copy is made to session.roster for all sessions.

All modifications to a roster should be done through the rostermanager.
