2022-05-16QOlmExpected and associated refactoringAlexey Rusakov
As mentioned in the commit introducing `Expected`, `QOlmExpected` is simply an alias for `Expected<T, QOlmError>`. This simplifies quite a few function signatures in `QOlm*` classes and collapses unwieldy `std::holds_alternative<>`/`std::get<>` constructs into a neat contextual bool cast and an invocation of `operator*` or `value()`/`error()` accessors that don't need to specify the type. While refactoring the code, I found a couple of cases of mismatching `uint32_t` and `qint32_t` in return values; a couple of cases where `decrypt()` returns `QString` which is in fact `QByteArray` (e.g., in `QOlmSession::decrypt()`); there's a repetitive algorithm in `Connection::Private::sessionDecryptPrekey()` and `sessionDecryptGeneral()`

That's a better primitive than just exposing SupportedAlgorithms list.
2022-02-16Use QHash instead of QMapAlexey Rusakov
We don't seem to need sorted associative containers in those cases.
2022-02-16CleanupAlexey Rusakov
A note on switching to QLatin1String for JSON key constants - this is more concise and barely affects (if at all) runtime performance (padding each QChar with zeros is trivial for assignment; and comparison can be done directly with the same performance as for two QStrings).
2022-02-16Add a few missing QUOTIENT_API stanzasAlexey Rusakov
Also, removed Q_GADGET macros from key verification events as those don't seem to do anything (no Q_ENUM/Q_FLAG things, namely).
