fetch-pack: support negotiation tip whitelist
During negotiation, fetch-pack eventually reports as "have" lines all commits reachable from all refs. Allow the user to restrict the commits sent in this way by providing a whitelist of tips; only the tips themselves and their ancestors will be sent. Both globs and single objects are supported. This feature is only supported for protocols that support connect or stateless-connect (such as HTTP with protocol v2). This will speed up negotiation when the repository has multiple relatively independent branches (for example, when a repository interacts with multiple repositories, such as with linux-next [1] and torvalds/linux [2]), and the user knows which local branch is likely to have commits in common with the upstream branch they are fetching.
