From 6e214960ce203d1d50d7bd6bd04eedee3afd0fa3 Mon Sep 17 00:00:00 2001
From: Nat Goodspeed <nat@lindenlab.com>

Subject: Define LLProcess::Params; accept create(const
 LLSDParamAdapter<Params>&). This allows callers to pass either LLSD formatted
 as before -- which all callers still do -- or an actual LLProcess::Params
 block.
