Instead of /sys/devices/virtual/ubi which will no longer be available
in future kernels, switch to /sys/class/ubi.
While at it fix unrelated arithmetic syntax error by guarding the
affected expression to not run on an empty string.

Bump version to reset PKG_RELEASE counter.
Add missing dependency on ucode-mod-math which is needed for the
mkdtemp() implementation used to format UBI volumes.

Don't use features which are not yet present in the version of ucode
currently shipped with OpenWrt (such as `fs.access()` or assuming raw
mode by default).
Fix syntax error in main executable.

* Fix build which was broken by a wrong path in the Makefile.
Adapt to ucode commit 4618807 ("main: rework CLI frontend"):
* ucode now no longer needs the {% %} around each code file, remove
that and safe one level of indentation.
* ARGV now no longer includes ucode executable and script itself
Fixes: 6350c7bc6 ("uvol: replace with re-write in ucode")
Signed-off-by: Daniel Golle <daniel@makrotopia.org>
Replace previous Shell draft-quality implementation of uvol with a
rewrite in ucode[1].
While the new code is slightly larger, it performs much better (as
we no longer fork() for parsing strings like in Shell with grep, sed
and friends).
Before:
time uvol list -j
[ ... ]
real 0m 0.82s
user 0m 0.13s
sys 0m 0.10s
After:
time uvol list -j
[ ... ]
real 0m 0.47s
user 0m 0.05s
sys 0m 0.05s

* auto-created meta volume
Automatically create volume '.meta' sized 0.01% of the total space
managed by uvol, the minimum size being 4 MiB.
This volume should be used to keep metadata about stored volumes, such
as container runtime configuration (in /var/run/uvol/.meta/uxc) or
the database of installed container packages.
* configurable LVM volume group
Allow setting volume group to be used by uvol using UCI.
This is useful on devices which do not boot off the device which
should be used for uvol and hence cannot make use of autopart and
physical volume detection based on kernel cmdline.
Use option vg_name in uvol section of fstab UCI config package.

Create UCI fstab mount sections for existing volumes on firstboot.
Introduce special handling for volumes with non-[:alnum:] prefix:
- do not create UCI sections for these 'hidden' volumes
- create UCI section for '.uxc' special volume with target
/var/state/uxc to be used for uxc config.

* 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

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.

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, ...).
