The luci-nginx metapackage selects some packages that we do not want to
select
1. luci-theme-bootstrap: Not needed, we use luci-theme-openwrt-2020
2. libiwinfo-lua: Not needed on non-WiFi targets such as panther, but
will be pulled in by other LuCI dependencies
It seems like CONFIG_BUILD_NLS it is not needed by anything, so disable
it. On an embedded device, we do not need localised output. End-users
will probably never interact via SSH with the device. So it is unclear
why it had been enabled in the first place.
In IOPSYSWRT, we use OpenSSL. Instead of shipping WolfSSL just for the
OpenWrt libustream library (which powers the uclient-fetch / wget
commands), make libustream use OpenSSL as well. This decreases security
maintenance and reduces overhead in image size and memory usage.
Similarly to 986fc5ea (Make dev-check check for SSH instead of non-HTTP,
2020-06-23), check for SSH instead of whether the repo was cloned via
HTTP. Developers might have other remotes such as OpenWrt's configured.
Remove CONFIG_TARGET_MULTI_PROFILE=y and
CONFIG_TARGET_PER_DEVICE_ROOTFS=y that were hardcoded in genconfig and
genconfig_min. Since feeds/targets commit 295d1566 (treewide: Add
MULTI_PROFILE and PER_DEVICE_ROOTFS config, 2021-08-05), the options are
added in feeds/targets.
Also bring the unmaintainable copy-paste of genconfig that is
genconfig_min in sync with genconfig with regards target-specific config
options.
Unify the iop-subcommands install_key and ssh_install_key to one script.
In addition:
* Support new key types such as ssh-ed25519 which is supported by
Dropbear nowadays. Also add unsupported ones to make them work
automatically in the future.
* For the install_key command, do not re-add keys already added
* Read keys loaded into SSH Agent as well, which is useful when working
with agent forwarding on a remote host or in a Docker container.
* For the ssh_install_key command also add keys added manually to the
build dir.
