Both ArchivedWAL_insert() and ArchivedWAL_delete_item() can cause
existing hashtable entries to move. The code didn't account for this
and could leave privateInfo->cur_file pointing at a dead or incorrect
entry, with hilarity ensuing. Likewise, read_archive_wal_page calls
read_archive_file which could result in movement of the hashtable
entry it is working with.
I believe these bugs explain some odd buildfarm failures, although
the amount of data we use in pg_waldump's TAP tests isn't enough to
trigger them reliably.
This code's all new as of commit
