Move everything module-related out of InspIRCd and into ModuleManager, there is a ModuleManager instantiated as InspIRCd::Modules. Several of the function names have changed slightly as well. e.g. Instance->FindModule(m_foobar.so); is now Instance->Modules->Find(m_foobar.so);
All modules in the core distribution should also be updated in line with these changes.
