sparse: Fix an "symbol 'format_subject' not declared" warning

In order to fix the warning, we add an extern declaration for this
function to the "commit.h" header file, along with all other non-
static functions defined in pretty.c. Also, we remove the function
declaration from builtin/shortlog.c, since it is no longer needed.
