* genrate UCI fstab configs for each volume before first 'up'
* remove UCI section on volume remove
* use autofs automounter for read-only volumes
* try umount on 'down'
* emulate hotplug events for UBI volume up/down
* more robust error paths

* make sure new volumes are in state 'down' until explicitely
requested to transition to 'up' state. Useful for additional
verification steps after writing a read-only volume.
* remove unused ubus events as blockd does that much better now

* quotes around all variables
* always use 'read -r' instead of 'read'
* some more minor shellcheck fixes
* reorder LVM ops for 'up' call to allow it to succeed

Emmit ubus events when volumes come up/down.
Make sure volume state is always well defined by introducing
additional state 'write-prepare' (wp) during mkfs.
Add init scripts to bring up volumes at boot.

Make sure filesystem is ready when volume becomes available.
Use 'write-once' as initial state for read-only volumes, only allow
writing to volumes in that state and transision to 'read-only' once
write has completed.
Also fix a typo which prevented 'list' command from working with LVM.

uvol is a wrapper-script which allows automated handling of storage
volumes. uvol currently comes with backend support for LVM2 and UBI,
covering practically all options for storage large enough to be
managed (NAND, SPI-NAND, eMMC, SATA, NVME, virtio-blk, ...).
