params: don't hand NULL values to param.set callbacks.
An audit by Dongdong Deng revealed that most driver-author-written param
calls don't handle val == NULL (which happens when parameters are specified
with no =, eg "foo" instead of "foo=1").
The only real case to use this is boolean, so handle it specially for that
case and remove a source of bugs for everyone else.
