Modules that are defined using relative urls to the master project are
assumed to be completely owned by the project. When running
"submodule update" from the top level, it is reasonable that the entire
project exists at the current master's remote. Using the
branch.$name.remote machinery, this remote can be different for each
branch and can be different than the current defaults in each submodule.
This teaches submodule to:
1) Possibly define the current master's remote in each submodule, using
the same relative url used by submodule init.
2) Fetch each submodule's updates from the master's remote.
Submodules defined using absolute urls (not relative to the parent) are
not touched by this logic. These modules are assumed to be independent
of the master project so submodule can do no better than to fetch from
their currently defined default remotes as already done.
