/* Daemon initializes, then sits in glib main loop, waiting for events.
* Events can be:
* - inotify: something new appeared under /var/cache/abrt
* - DBus: dbus message arrived
* - signal: we got SIGTERM or SIGINT
*
* DBus methods we have:
* - GetCrashInfos(): returns a vector_crash_infos_t (vector_map_vector_string_t)
* of crashes for given uid
* v[N]["executable"/"uid"/"kernel"/"backtrace"][N] = "contents"
* - CreateReport(UUID): starts creating a report for /var/cache/abrt/DIR with this UUID.
* Returns job id (uint64).
* Emits JobStarted(client_dbus_ID,job_id) dbus signal.
* After it returns, when report creation thread has finished,
* JobDone(client_dbus_ID,UUID) dbus signal is emitted.
* - GetJobResult(UUID): returns map_crash_report_t (map_vector_string_t)
* - Report(map_crash_report_t (map_vector_string_t)):
* "Please report this crash": calls Report() of all registered reporter plugins
* Returns report_status_t (map_vector_string_t) - the status of each call
* - DeleteDebugDump(UUID): delete corresponding /var/cache/abrt/DIR. Returns bool
* - GetPluginsInfo(): returns vector_map_string_t
* - GetPluginSettings(PluginName): returns map_plugin_settings_t (map_string_t)
* - SetPluginSettings(PluginName, map_plugin_settings_t): returns void
* - RegisterPlugin(PluginName): returns void
* - UnRegisterPlugin(PluginName): returns void
* - GetSettings(): returns map_abrt_settings_t (map_map_string_t)
* - SetSettings(map_abrt_settings_t): returns void
*
* DBus signals we emit:
* - Crash(progname,uid) - a new crash occurred (new /var/cache/abrt/DIR is found)
* - JobStarted(client_dbus_ID,job_id) - see CreateReport above.
* Sent as unicast to the client which did CreateReport.
* - JobDone(client_dbus_ID,UUID) - see CreateReport above.
* Sent as unicast to the client which did CreateReport.
* - Warning(msg,job_id)
* - Update(msg,job_id)
* Both are sent as unicast to last client set by set_client_name(name).
* If set_client_name(NULL) was done, they are not sent.
*
* TODO:
* - API does not really need JobStarted dbus signal at all, and JobDone signal
* does not need to pass any parameters - out clients never sent multiple
* CreateReport's.
