Shift ARGV until actual parameters start to compensate for older
versions of ucode passing the complete cmdline.

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

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

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, ...).
