This patch adds structures and functions to reroute error and warning
logs to log report, if it's set.
There are 5 new functions:
- log_set_report
Set log report where logging will be rerouted.
- log_set_report_context
Set context globally so any report_cmdlog call will use it.
- log_set_report_object_type
Set object type globally so any report_cmdlog call will use it.
- log_set_report_object_name_and_id
Set object ID and name globally so any report_cmdlog call will use it.
- log_set_report_object_group_and_group_id
Set object group ID and name globally so any report_cmdlog call will use it.
These functions will be called during LVM command processing so any logs
which are rerouted to log report contain proper information about current
processing state.
