* Multi-purpose session/context object.
*
* <p>Confusingly, Gerrit has two ideas of what a "context" object is: one for Guice {@link
* RequestScoped}, and one for its own simplified version of request scoping using {@link
* ThreadLocalRequestContext}. This class provides both, in essence just delegating the {@code
* ThreadLocalRequestContext} scoping to the Guice scoping mechanism.
*
* <p>It is also used as the session type for {@code UploadPackFactory} and {@code
* ReceivePackFactory}, since, after all, it encapsulates all the information about a single
* request.
