In preparation for switching all targets to the staged sysupgrade
mechanism, upgraded is always built, and the "nandupgrade" ubus method is
renamed to "sysupgrade".
To make the migration easier, support for the old name "nandupgrade" and
the "upgrade" method that will become unused with the staged sysupgrade is
retained for now.
Signed-off-by: Matthias Schiffer <mschif...@universe-factory.net>
Note: obviously, this patch should go into the procd repo when it is
actually applied; it is provided like this for now to allow easier testing
of the whole series.

+Subject: [PATCH 1/4] system: always support staged sysupgrade
+
+In preparation for switching all targets to the staged sysupgrade
+mechanism, upgraded is always built, and the "nandupgrade" ubus method is
+renamed to "sysupgrade".
+
+To make the migration easier, support for the old name "nandupgrade" and
+the "upgrade" method that will become unused with the staged sysupgrade is
+retained for now.
