[OpenWrt-Devel] [PATCH luci 1/2] luci-mod-system: use "system" new "validate_firmware_image" ubus method

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

This new ubus method provides more properly-formatted details about
firmware file. Use it to check if uploaded image is valid.

The old "sysupgrade --test" method is left for now to provide stderr
output.
