This changes the crash export mechanism in Microdroid. For this, we create module tombstone_handler which exports methods very similar to tombstoned.h For Microdroid (detected using prop: ro.hardware): It calls newly introduces microdroid specific methods to connect/notify completion of crash. Individual methods: connect -> For Android, it would connect to tombstoned which would send it the fd corresponding to newly created file on /data/tombstone_ . For Microdroid, we connect to tombstone server on host via vsock & populate these sockets as the output fd. crash_dump, in the later case, would directly write on the socket(s). notify_completion: For Microdroid, it would simply shutdown the vsock connections. Note when OS is not Microdroid: It calls corresponding methods of tombstoned_client, essentially serving as a proxy.
