Avoid races with GC and between different concurrent backups by limiting the
number of concurrent backups per group to 1 and forbidding the deletion of the
previous finished backup, if a new one is currently running.

Fixes several issues that could lead to failed backups, or even worse,
"successful" backups that were really missing chunks.


proxmox-backup: Stefan Reiter (5):
  fix typo: avgerage to average
  datastore: prevent deletion of snaps in use as "previous backup"
  tools: add nonblocking mode to lock_file
  backup: use flock on backup group to forbid multiple backups at once
  backup: ensure base snapshots are still available after backup
