git-submodule: rename shell functions for consistency

This renames the shell functions used in git-submodule that
implement top-level subcommands.  The rule is that the
subcommand $foo is implemented by cmd_$foo function.

A noteworthy change is that modules_list() is now known as
cmd_status().  There is no "submodule list" command.
