Subject: [PATCH] libdm: report: add dm_report_group_output_and_pop_all

The dm_report_group_output_and_pop_all calls dm_report_output and
dm_report_group_pop for all the items that are currently in report
group. This is just a shortcut that makes it easier to output and
pop group's content so the group handle can be reused again without
a need to initialize and configure it again.

The functionality of dm_report_group_output_and_pop_all is the
same as dm_report_destroy but without destroying the report group
handle.
