ipmi: fixed respond sync, get message, try get message, try send message event: detach event emitter from file signals: basic implementation linker: fixed zero symbol relocation, fixed exec relocation shared_cv/mutex: implement eintr response support shared_cv: fixed possible loop instead of wait ipmi: implement invoke async, respond async, get result, get client app id, client get name rpcsx-os: add safemode flag
