It's been a long standing issue that init cannot respond to property set messages when it is running a builtin command. This is particularly problematic when the commands involve IPC to vold or other daemons, as it prevents them from being able to set properties. This change has init run property service in a thread, which eliminates the above issue. This change may also serve as a starting block to running property service in an entirely different process to better isolate init from handling property requests. Reland: during reboot, init stops processing property_changed messages from property service, since it will not act on these anyway. This had an unexpected effect of causing future property_set calls to block indefinitely, since the buffer between init and property_service was filling up and the send() call from property_service would then block. This change has init tell property_service to stop sending it property_changed messages once reboot begins. Test: CF boots, walleye boots, properties are set appropriately Change-Id: I26902708e8be788caa6dbcf4b6d2968d90962785
