mod_c2s, mod_s2s, mod_component, mod_bosh, mod_websockets: Set default stanza size limits c2s/bosh/ws streams will default to 256KB, s2s and components to 512KB. These values are aligned with ejabberd's default settings, which should reduce issues related to inconsistent size limits between servers on the XMPP network. The previous default (10MB) is excessive for any production server, and allows significant memory usage by even unauthenticated sessions.
