bf304d10e9 base-files: sysupgrade: include uci-defaults script disabling services
Disabled services should be kept disabled after sysupgrade. This can be
easily handled using a proper uci-defaults script.

Extend sysupgrade to check for disabled services, generate uci-defaults
script disabling them and include it in backup.

4fa9aaf0be base-files: sysupgrade: always setup overlay when creating backup
Setting overlay while creating backup allows including extra files in
archive without actually writing them to flash. Right now this feature
is limited to /etc/backup/ directory and is used only for including
installed_packages.txt.

Extend this solution to make it more generic:
1. Always mount overlay while creating backup
2. Overlay whole / to don't limit it to /etc/backup/

This allows including any additional files in backups and adding more
sysupgrade features.

700907bc63 base-files: sysupgrade: always cleanup after backups
When tar was failing, it was exiting immediately. Some files and the
tmpfs mount (-k) would remain breaking the next backup attempt.

Also remove redundant $? from exit builtin call as exit already returns
the last command exit code when called.

14ac91c68c base-files: sysupgrade: do not hide tar errors
tar stderr was probably discarded only to remove this message:

  tar: removing leading '/' from member names

However, together with that, any other error would also be discarded.
It is easier to fix that allowing the error message to be printed.

In sysupgrade, the backup file list only uses absolute paths. That way,
the solution is to remove the leading '/' from all files (sed) and chdir
to / (option -C /)

102855b3c1 base-files/leds: save led color value if available
There are monochrome LEDs that can only display one color. However, there
are also LEDs that can display multiple colors. This can be tested in the
led subsystem of the kernel if the files 'multi_index' and 'multi_intensity'
are present in the folder '/sys/class/leds/<ledname>'.

Until now it was not possible to reset the default color. This commit adds
the missing information in the file '/var/run/led.state' so that the bootup
color can be seen on the LED again when the LED configuration has been changed.

This is needed e.g. by uhttpd-mod-ubus which after installation in a

1. Update uhttpd config using its uci-defaults script
2. Reload uhttpd

While this approach makes sense there is a risk it'll blow up some

base-files: fix wrong ucidef_set_network_device_mac network-device entry
The ucidef_set_network_device_* functions in uci-defaults.sh disagree
on whether to use "network-device" or "network_device" in board.json.
With the additional caveat that jshn will translate hyphens (-) into
underscores (_). This casues problems in netifd which expected
"network_device" causing boards which depend on assigning MACs in
board.json via uci-defaults.sh (or jshn in general) to fail.

This commit addresses the issue by using network_device in
uci-defaults.sh.

The bug was uncovered in the forums here:
https://forum.openwrt.org/t/support-for-rtl838x-based-managed-switches/57875/2596

This was exposed by commit 4ebba8a05d ("realtek: add support for HPE
1920-8g-poe+") where the board_config_load call from 03_gpio introduced
the key normalization by jshn.

base-files: sysupgrade: Add 2 sec sleep into process KILL loop
Add 2 seconds sleep after each forcibly killed/tried-to-kill process
in the final process termination loop in sysupgrade stage2.

This is needed especially for qualcommax/ipq807x, where ath11k
wireless driver may have a long 10-20 seconds delay after termination
before actually getting killed. This often breaks sysupgrade.

The current KILL loop in kill_remaining does all 10 kill attempts
consecutively without any delay, as evidenced here in a failing sysupgrade.
It does not allow any time for the process to finalize its internal
termination.

It turns out, that we don't even need this check at all because, when
looking for all existin eth*s on a system, and take the highest index
and then iterate a set of devices and rename to eth${highest_index+n},
it is guaranteed that there will be no conflict.

e8625c89ef treewide: replace /sys/devices/virtual/ubi by /sys/class/ubi
Starting from Linux Kernel version 6.3 UBI devices will no longer be
considered virtual, but rather have an MTD device parent. Hence they
will no longer be listed under /sys/devices/virtual/ubi which is
used in multiple places in OpenWrt. Prepare for future kernels by
using /sys/class/ubi instead of /sys/devuces/virtual/ubi.

base-files: ipcalc.sh: use shebang to invoke awk
There's hardly an shell logic in ipcalc.sh and a $* that would garble
parameter positions.
Move the awk invokation to the shebang.

A rename from "ipcalc.sh" to "ipcalc" is desirable but could prove tricky
with packages in other repositories depending on the filename.

base-files: ipcalc.sh: fail when network is too small
It's possible to move range boundaries in a way that the start address
lies behind the end address.
Detect this condition and exit with an error message.
