[PATCH v3 0/3] Use a standalone kdump emergency shell

Currently kdump use some wrapper around dracut emergency service and emergency shell, this have many problems: - If dracut-initqueue failed back to emergency mode due to timeout, and faiure action is set to dump_to_rootfs, kdump will try start initqueue again, lead to double timeout error. - Dracut's emergency shell have many builtin actions, like perform dracut emergency_action, ask for root password, generate rdsosreport etc. This series remove the emergency wrapper, and use a standalone kdump emergency shell. Kdump will always perform final_action after kdump shell, so simplified version works fine. Update from V2: Fix an redundant string escaping issue found by Coiby. Update from V1: Fix initqueue status detection in patch 1/3, thanks to Coiby.
