builtin/clone.c: add --reject-shallow option
In some scenarios, users may want more history than the repository
offered for cloning, which happens to be a shallow repository, can
give them. But because users don't know it is a shallow repository
until they download it to local, we may want to refuse to clone
this kind of repository, without creating any unnecessary files.
The '--depth=x' option cannot be used as a solution; the source may
be deep enough to give us 'x' commits when cloned, but the user may
later need to deepen the history to arbitrary depth.
Teach '--reject-shallow' option to "git clone" to abort as soon as
we find out that we are cloning from a shallow repository.
