Fix all the tests for the solana bridge program so that we can start
running it in CI.
Use the `solana-program-test` crate as the test framework. Previously,
running the tests required spinning up a test validator and manually
deploying the program there. Now developers can just do `cargo test-bpf`
to run the tests without needing any additional setup (beyond installing
the solana tools). This also lets us split out the tests so that they
can be run separately rather than having to run everything sequentially
in a single integration test.
Merge all the separate solana crates into a single workspace. This is
the same thing we do for terra and will make it easier to check / lint /
test all the crates together.
This will make is easier to separate modules and solitaire in the future.
We also get rid of the old bridge code.
