mod_http_xep227: Add support for import via APIs rather than direct store manipulation In particular this transitions PEP nodes and data to be imported via mod_pep's APIs, fixing issues with importing at runtime while PEP data may already be live in RAM. Next obvious candidate for this approach is rosters, so clients get immediate roster pushes and other special handling (such as emitting subscribes to reach the desired subscription state).

1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	50 A certain number of events are allowed per second, given by
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	51 muc\_event\_rate. An event rate of 1 allows one event per second, and
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	52 event rate of 3 allows three events per second, and 0.5 allows one event
