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).
-- Send carbons v0 style copies of incoming messages to clients which
-- are not (yet) capable of Message Carbons (XEP-0280).
--
-- This extension integrates with the mod_carbons plugin in such a way
-- that a client capable of Message Carbons will not get a v0 copy.
--
-- This extension can be enabled for all users by default by setting
-- carbons_copies_default = true.
--
-- Alternatively or additionally setting carbons_copies_adhoc = true
-- will allow the user to enable or disable copies through Adhoc
-- commands.
