Add ability to dynamically load an RDBC driver

[andygrove]

Currently, it is necessary to statically link to all possible RDBC driver implementations that need to be used at runtime but one of the main benefits of ODBC/JDBC is that new drivers can be loaded at runtime, so we need a similar mechanism here.

Would this be a subclass, or would this be something like libdl that implements dynamic loading of shared libs? I'm not sure if this is supported in Rust, but it's a possible solution. I would think that if the drivers are lightweight enough, they can all be compiled into a single runtime?

[andygrove]

It would need to be dynamic loading of shared libs so that a user can use any driver with a product without having to have a version of the product that is compiled against the driver they want to use.

Does anyone really load JDBC drivers at runtime in practice? I always thought that was an obscure thing to do.

[andygrove]

Actually, this is very common in desktop products where the user can add new JDBC drivers through the user interface without the need to restart the application.
