 Move renameat() to the proper header.

 Commit e9cf5ab3 moved the renameat() declaration from sys/stdio.h to
 stdio.h, but this is incompatible with the normal header setup.
 This moves it back to restore compatibility, but requires knowledge
 of the SDK version to cope with the absence of sys/stdio.h in
 pre-10.10 SDKs.  This is handled via the new sdkversion.h.
