dwarf_decl_file uses dwarf_attr_integrate to get the DW_AT_decl_file
attribute. This means the attribute might come from a different DIE
in a different CU. If so, we need to use the CU associated with the

block on the work queue until it becomes empty (rather than normal
consumers that block on it until it becomes non-empty).  Use this
facility for the groomer thread to avoid working at the same time as
the scanner threads.  Use this for the fts traversal thread for
similar reasons.  One user-visible effect: response to SIGUSR1 and
SIGUSR2 will wait until the work queue runs empty, but the man page
was unspecific so does not need changing.

It's not obvious how to test this with a tests/ dataset so small that
scanning takes negligible time, so the former races are very tight.

P.S. We also evaluated using sqlite level transactions to isolate the
scanner thread groups-of-operations from the groomer.  These
experiments failed to produce a nominally concurrent debuginfod,

debuginfod: Check the DEBUGINFOD_URLS environment variable early in client.

as possible. Simply return early with ENOSYS if no servers are
configured. This means we won't check

This does change the behavior of the debuginfod_find calls slightly.
Previously we would setup and check the cache if the given build-id
was valid. Which might have provided a result if an earlier client
had run with the same cache and valid server URLs which knew about
that particular build-id. Now we don't return any cached results
unless at least one server is configured.

This prevents selinux errors when the library is used in a confined
