ca761d7697 Avoid creating an aggregation context unnecessarily if the function is 
called against 0 rows.

b189f6ba66 Change how Aggregate works when called on no rows. 
Before this commit, if the aggregate function was called on 0 rows, it
would always return NULL (and never call Aggregate::init() or
finalize()). Now, init() and finalize() are always called to get the
result of the function, even if step() is never called.

7b29277d6f Use discard() instead of cacheable = false to avoid prevent cached 
statements from returning to the cache.

aac4d59fcc Change Error from a struct to an enum (BREAKING CHANGE). 
This allows us to separate out the underlying SQLite error codes from
errors that occur on the Rust side.
