  - Merge "liblog: add a timeout for logd command socket operations"
  - liblog: add a timeout for logd command socket operations
    
    Add a 2s timeout for logd command socket operations:
      android_logger_clear
      android_logger_get_log_readable_size
      android_logger_get_log_size
      android_logger_set_log_size
      android_logger_get_statistics
      android_logger_get_prune_list
      android_logger_set_prune_list
    
    That correspond to:
      logcat -c
      logcat -g
      logcat -G
      logcat -S
      logcat -p
      logcat -P
    
    These operations should return immediately in typical circumstances,
    but if logd is stuck, they would otherwise block indefinitely.  This
    allows the commands to gracefully timeout instead.
    
    Test: kill -s STOP `pidof logd`; logcat -g (and other options)
          times out appropriately
    Test: logcat -g (and other options) work successfully otherwise
