Jeremy Allison 306783d6f5 lib: modules: Change XXX_init interface from XXX_init(void) to XXX_init(TALLOC_CTX *)
Not currently used - no logic changes inside.

This will make it possible to pass down a long-lived talloc
context from the loading function for modules to use instead
of having them internally all use talloc_autofree_context()
which is a hidden global.

Updated all known module interface numbers, and added a
WHATSNEW.
