Jens Lehmann 496b35e7e0 fetch/pull: Recursively fetch populated submodules ...

Until now you had to call "git submodule update" (without -N|--no-fetch
option) or something like "git submodule foreach git fetch" to fetch
new commits in populated submodules from their remote.

This could lead to "(commits not present)" messages in the output of
"git diff --submodule" (and in "git gui" and "gitk") after fetching
or pulling new commits in the superproject and is an obstacle for
implementing recursive checkout of submodules.

This patch recursively fetches each populated submodule from the url
configured in the .git/config of the submodule at the end of each
"git fetch" or during "git pull" in the superproject. This new behavior
can be disabled by using the new --no-recursive option.

t7403 had to be changed to use the --no-recursive option for pull.
