If shallow information is not ready by the time index-pack is run, index-pack may be led to non-existent objects. Make fetch-pack save shallow file to disk before invoking index-pack. git learns new global option --shallow-file to pass on the alternate shallow file path. Undocumented (and not even support --shallow-file= syntax) because it's unlikely to be used again elsewhere.

This is expensive on large repositories. This patch attempts to mitigate the impact in this special case. In the "good" clone case, we only have one pack. If all of the following are met, we can be sure that all objects reachable from the new refs exist, which is the intention of running "rev-list ...": - all refs point to an object in the pack - there are no dangling pointers in any object in the pack - no objects in the pack point to objects outside the pack The second and third checks can be done with the help of index-pack as a slight variation of --strict check (which introduces a new condition for the shortcut: pack transfer must be used and the number of objects large enough to call index-pack). The first is checked in check_everything_connected after we get an "ok" from index-pack. "index-pack + new checks" is still faster than the current "index-pack + rev-list", which is the whole point of this patch. If any of the conditions fail, we fall back to the good old but expensive "rev-list ..". In that case it's even more expensive because we have to pay for the new checks in index-pack. But that should only happen when the other side is either buggy or malicious.

This shortcut does not apply to unpack-objects code path either because the number of objects must be small in order to trigger that code path.
