Got RID of redundant coercions in longobject.c (as spotted by Greg

Stein -- thanks!).  Incidentally removed all the Py_PROTO macros
from object.h, as they prevented my editor from magically finding
the definitions of the "coercion", "cmpfunc" and "reprfunc"
typedefs that were being redundantly applied in longobject.c.
