Refactor error handling (#2136)
* Add crate snafu

* Replace all inline structs in AnkiError

* Derive Snafu on AnkiError

* Use snafu for card type errors

* Use snafu whatever error for InvalidInput

* Use snafu for NotFoundError and improve message

* Use snafu for FileIoError to attach context

Remove IoError.
Add some context-attaching helpers to replace code returning bare
io::Errors.

* Add more context-attaching io helpers

* Add message, context and backtrace to new snafus

* Utilize error context and backtrace on frontend

* Rename LocalizedError -> BackendError.
* Remove DocumentedError.
* Have all backend exceptions inherit BackendError.

* Rename localized(_description) -> message

* Remove accidentally committed experimental trait

* invalid_input_context -> ok_or_invalid

* ensure_valid_input! -> require!

* Always return `Err` from `invalid_input!`

Instead of a Result to unwrap, the macro accepts a source error now.

* new_tempfile_in_parent -> new_tempfile_in_parent_of

* ok_or_not_found -> or_not_found

* ok_or_invalid -> or_invalid

* Add crate convert_case

* Use unqualified lowercase type name

* Remove uses of snafu::ensure

* Allow public construction of InvalidInputErrors (dae)

Needed to port the AnkiDroid changes.

* Make into_protobuf() public (dae)

Also required for AnkiDroid. Not sure why it worked previously - possible
bug in older Rust version?
