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.

The FE was creating class loaders with the HDFS locations of Hive UDF
libs, rather than the local locations created by the BE. Our tests
still passed since we only used UDFs already on the classpath
(e.g. Hive builtins).
