Update nitrokey crate to 0.4.0-alpha.3
This change updates the version of the nitrokey crate that we use to 0.4.0-alpha.3. This version is the supposedly last pre-release before 0.4.0, with no further major anticipated changes. In order to integrate with this new version we have to adjust the way we connect to a Nitrokey device by funneling those connection requests through a global manager object. The rationale behind that step being that the underlying libnitrokey actually cannot handle access of multiple devices at the same time, and so the manager object is used to prevent accidental wrong concurrent usage. Because a device object now effectively keeps a reference to the manager, we need to provide an additional lifetime to that and derived objects. Lastly, the use of a manager is also the reason why the tests had to be adjusted to no longer accept device objects in their signatures, but only the respective model for which to invoke the test. That is required because, as elaborated earlier on, having a device object implies having taken a reference to a manager (in that case owned by nitrokey-test), and that reference clashes with the nitrocli code itself attempting to take the manager. We side step this problem by merely accepting a Model object, which can be passed around independently of the manager itself, meaning that nitrokey-test does not need to hold such a reference while the test is run.

+This directory contains snippets of code that should yield a
+warning/note/help/error at compilation. Syntax of annotations is described in
+[rust documentation](https://github.com/rust-lang/rust/blob/master/src/test/COMPILER_TESTS.md).
+For more information check out [`compiletest` crate](https://github.com/laumann/compiletest-rs).
+
+To run compile tests issue `cargo +nightly --test`.
+
+## Notes on working with `compiletest` crate
+
+* Currently code that is inside macro should not be annotated, as `compiletest`
+ crate cannot deal with the fact that macro invocations effectively changes
+ line numbering. To prevent this add a `// error-pattern:<your error message here>`
+ on the top of the file and make sure that you set `deny` lint level
+ if you want to test compiler message different than error.
+* `compiletest` crate by default sets `allow(dead_code)` lint level so make sure
+ that you change it to something suiting your needs even if the warning is
+ issued prior to any macro invocation.
+* If you get a message `error: 0 unexpected errors found, 1 expected errors not found`
+ despite the fact that some error was bound to occur don't worry - it's a known
+ issue in the `compiletest` crate and your error was probably not registered -
+ make sure that your annotations are correct and that you are setting correct
+ lint levels.
