go/xenlight: More informative error messages
If an error is encountered deep in a complicated data structure, it's
often difficult to tell where the error actually is. Make the error
message from the generated toC() and fromC() structures more
informative by tagging which field being converted encountered the
error. This will have the effect of giving a "stack trace" of the
failure inside a nested data structure.
NB that my version of python insists on reordering a couple of switch
statements for some reason; In other patches I've reverted those
changes, but in this case it's more difficult because they interact
with actual code changes. I'll leave this here for now, as we're
going to remove helpers.gen.go from being tracked by git at some point
in the near future anyway.
