This patch cleans up analysis and execution of scalar and aggregate functions so that there is no difference between how builtins and user functions are handled. The only difference is that the catalog is populated with the builtins all the time. The BE always gets a TFunction object and just executes it (builtins will have an empty hdfs file location). This removes the opcode registry and all of the functionality is subsumed by the catalog, most of which was already duplicated there anyway. This also introduces the concept of a system database; databases that the user cannot modify and is populated automatically on startup.
