2022-08-03	refactor: Replace BResult with util::Result	Ryan Ofsky
	Rename `BResult` class to `util::Result` and update the class interface to be more compatible with `std::optional` and with a full-featured result class implemented in https://github.com/bitcoin/bitcoin/pull/25665. Motivation for this change is to update existing `BResult` usages now so they don't have to change later when more features are added in #25665. This change makes the following improvements originally implemented in #25665: - More explicit API. Drops potentially misleading `BResult` constructor that treats any bilingual string argument as an error. Adds `util::Error` constructor so it is never ambiguous when a result is being assigned an error or non-error value. - Better type compatibility. Supports `util::Result<bilingual_str>` return values to hold translated messages which are not errors. - More standard and consistent API. `util::Result` supports most of the same operators and methods as `std::optional`. `BResult` had a less familiar interface with `HasRes`/`GetObj`/`ReleaseObj` methods. The Result/Res/Obj naming was also not internally consistent. - Better code organization. Puts `src/util/` code in the `util::` namespace so naming reflects code organization and it is obvious where the class is coming from. Drops "B" from name because it is undocumented what it stands for (bilingual?) - Has unit tests.

2022-07-08	Introduce generic 'Result' class	furszy
	Useful to encapsulate the function result object (in case of having it) or, in case of failure, the failure reason. This let us clean lot of boilerplate code, as now instead of returning a boolean and having to add a ref arg for the return object and another ref for the error string. We can simply return a 'BResult<Obj>'. Example of what we currently have: ``` bool doSomething(arg1, arg2, arg3, arg4, &result, &error_string) { do something... if (error) { error_string = "something bad happened"; return false; } result = goodResult; return true; } ``` Example of what we will get with this commit: ``` BResult<Obj> doSomething(arg1, arg2, arg3, arg4) { do something... if (error) return {"something happened"}; // good return {goodResult}; } ``` This allows a similar boilerplate cleanup on the function callers side as well. They don't have to add the extra pre-function-call error string and result object declarations to pass the references to the function.
