Subject: Issue #9012: "Separate compilation of time and datetime modules."
 Segregated code shared between time and datetime modules into
 Modules/_time.c.  Added a new header file, Modules/_time.h, which will be
 used instead of Include/timefuncs.h for declarations shared between time and
 datetime modules.
