[committed] Make some variables and functions static

[Tom de Vries]

Hi,

There is a number of variables and functions in dwz.c that is external but
could be static.  Make these static.

Committed to trunk.

Thanks,
- Tom

Make some variables and functions static

2021-03-15  Tom de Vries  <tdevries@suse.de>

	* dwz.c (odr, odr_mode, odr_mode_parsed, odr_active_p, stats)
	(dump_die, verify_edges, die_count_method_parsed)
	(deduplication_mode_parsed): Make static.
