[quick-cluster 2/4] QUICK CLUSTER: Fold quick-cluster.h into quick-cluster.c.

[Ben Pfaff]

It's unusual to put 'static' function prototypes into a header file:
header files are usually used to export declarations for use by other
source files, but 'static' functions cannot be called outside their
own source files.
