Any output from the LOG family will now go to stderr and logcat on the device. stderr is usually redirected to a log file, but that is now inhibited for adbd if being run from a tty (useful when debugging with the serial console). This also fixes sending logs to the file on device for the trace mask of "all". The "all" tag was specifically handled to return early from the function, preventing the file initialization from happening. Change-Id: Id253577bfd1500fbce92dbfba0f9be23dbfd5ee4
