Remove dc_open() from the Rust API

Browse Source 
This means the Context becomes a struct following the normal Rust
conventions where when it is created it is usable.  This will over
time allow removing a lot of runtime checks and simplify code.  Many
members will no longer need to be Options or similar.

The C API needs to remain compatible so hides the implementation of
this behind another struct which can be opened and closed.
