[PATCH] Support alternates and http-alternates in http-fetch
This allows the remote repository to refer to additional repositories
in a file objects/info/http-alternates or
objects/info/alternates. Each line may be:
a relative path, starting with ../, to get from the objects directory
of the starting repository to the objects directory of the added
repository.
an absolute path of the objects directory of the added repository (on
the same server).
(only in http-alternates) a full URL of the objects directory of the
added repository.
