send-pack: take refspecs over stdinjk/send-pack-many-refspecs
Pushing a large number of refs works over most transports, because we implement send-pack as an internal function. However, it can sometimes fail when pushing over http, because we have to spawn "git send-pack --stateless-rpc" to do the heavy lifting, and we pass each refspec on the command line. This can cause us to overflow the OS limits on the size of the command line for a large push. We can solve this by giving send-pack a --stdin option and using it from remote-curl. We already dealt with this on the fetch-pack side in 078b895 (fetch-pack: new --stdin option to read refs from stdin, 2012-04-02). The stdin option (and in particular, its use of packet-lines for stateless-rpc input) is modeled after that solution.
