Improve display for tor-dircache errors.

2022-07-07T18:07:04Z

These errors no longer use Debug to dump the `Option`, but instead produce reasonable text. Also, I've fixed the SourceInfo Display implementation so that it now says that it got the error "from $source via $circuit" rather than the other way around.

dirclient: Generalize MdSha256Empty to EmptyRequest.

2022-07-07T18:07:04Z

(It makes sense to use this for things that are not in fact lists of SHA256 digests of Microdescriptors.)

Do not include error source() in display() format.

2022-06-21T18:14:14Z

According to doc/Errors.md, and in keeping with current best practices, we should not include display an error's `source()` as part of that error's display method. Instead, we should let the caller decide to call source() and display that error in turn. Part of #323.

tor-dirclient: Require that self.digests is nonempty

dirclient: add the ability to reject circuits that are too skewed.

2022-05-11T17:48:55Z

This will help implement #466.

dirclient: Collect and expose peer information from errors.

2022-03-21T13:06:32Z

This commit refactors the dirclient error type into two cases: errors when constructing a circuit, and errors that occur once we already have a one-hop circuit. The latter can usually be attributed to the specific cache we're talking to. This commit also adds a function to expose the information about which directory gave us the info.

Replace TorNetworkError with TorDirectoryError

2022-02-22T20:41:01Z

This is still not as specific as we want; but there's already a TODO comment in tor-dirclient::err about fixing that at some point in the future.

dirclient: Remove HttpStatus error variant

2022-02-17T20:12:00Z

Getting a non-200 status is no longer a failure condition; it's just a different kind of answer. Closes #349.

Correct ErrorKinds for some tor-dirclient errors.

2022-02-17T17:26:18Z

Rename ExitTimeout to RemoteNetworkTimeout.
