Fixes:

• fd.o #34025: when an Observer with Recover=TRUE catches up on channels,
   don't miss out channels that have run their observers but have not
   completed dispatching, mainly those waiting for approvers (smcv)

• Fix various memory leaks (fledermaus)

• If a storage plugin changes our nickname, propagate it to the CM (fledermaus)

• The McdTransport framework should have considered "no plugins" to be
   equivalent to "procced", not "abort" (fledermaus)

• Some files were missing G_END_DECLS, which broke C++ includes (fledermaus)
