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.

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.

3913e89f94 Allow user scalar functions to return results. 
This removes the need for scalar functions to have direct access to the
context (in order to set the return value).

81ec7fe7cd Add get to function::Context. 
This allows user-defined functions to now only accept a `Context`, as it
embeds the arguments inside itself.
