Provide a machine-processable exception which is not based on strings

When using LibGit2Sharp with a remote repository, sometimes errors occur. Those are throw as LibGit2SharpException. At this point these exceptions can only be distinguished from each other by the exception message.
Is there a way to get certain server responses like a 404 as HTTPStatusCode and not have to extract it from the message? For example, if the URL is incorrect (server exists, but path is not valid), a LibGit2SharpException is thrown which returns "invalid url, missing path" as a message. Here a HTTPStatusCode inside the Exception would be better suited to distinguish between different server responses and to react accordingly.

Comece rastreando como LibGit2SharpException é criada quando operações em repositórios remotos recebem erros do servidor, especialmente o exemplo de URL inválida descrito na issue. Determine como um status HTTP processável por máquina poderia ser exposto sem depender da mensagem e adicione cobertura para respostas 404 e respostas de caminhos inválidos. A tarefa estará concluída quando os chamadores puderem distinguir essas respostas programaticamente.
