Add log/debug_classes to lvm.conf to allow debug messages to be classified and filtered at runtime. The dm_errno field is only used by log_error(), so I've redefined it for log_debug() messages to hold the message class. By default, all existing messages appear, but we can add categories that generate high volumes of data, such as logging all traffic to/from lvmetad.
