Alasdair G Kergon 7f747a0d73 logging: add debug classes ...

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.
