[patch 1/8] Immediate values - Global modules list and module mutex

[Mathieu Desnoyers]

Remove "static" from module_mutex and the modules list so it can be used by
other builtin objects in the kernel. Otherwise, every code depending on the
module list would have to be put in kernel/module.c. Since the immediate values
depends on the module list but can be considered as logically different, it
makes sense to implement them in their own file.
