commit 55681f9d66b788b2e86a5ad3c0722904fa020962
Author: Alan Coopersmith <alan.coopersmith at oracle.com>
Date:   Tue Jul 30 22:15:28 2013 -0700

    Make various helper & callback functions private to session.c
    
    Nothing else ever called them, so no reason to export them.

commit cf88a8c16958ddfaeff6349d30c6c423fc4a7afa
Author: Alan Coopersmith <alan.coopersmith at oracle.com>
Date:   Tue Jul 30 22:11:51 2013 -0700

    Convert remaining K&R function declarations to C89 style
    
    Many existing function declarations were C89, and headers all use C89
    prototypes, but a few function declarations had been left in the old
    style.

commit ea349d3c406695665322c71caf5ea3c970cb3155
Author: Alan Coopersmith <alan.coopersmith at oracle.com>
Date:   Tue Jul 30 21:57:04 2013 -0700

    Use (void) to declare functions that take no arguments, instead of ()
    
    It's time for C89.
