Subject: [PATCH] Removed unused (and unimplemented) stackcheck() and
 stackoverflow() routines

These routines were stubs that did nothing and were not called from anywhere
so lack value in even providing a template or hook for a fuller implementation.
Also note that "stackcheck" conflicts with a predefined symbol in some runtime
libraries.  Should these be implemented in the future they should use a
maiko-specific name.
