params: Simplify code

Browse Source 
Standard javascript now has Object.assign() which is very similar to
Params.parse(), except that the latter by default disallows "extra"
parameters. We can still leverage the standard API by simply
implementing the error check, and then call out to Object.assign()
for the actual parameter merging.
