Move few remaining src/utils files to backend/port so everything is in

one place.  Everything may be moved to src/utils eventually.

Add DLLINIT variable to simplify makfiles.

-The utils directory contains components that are used by multiple subsystems
-in the Postgres source tree.  We don't want subsystems reaching into other
-subsystems' directories and messing with the modularity of the system, so
-we gather any cross-subsystem utilities here.
-
-In particular, programs that form an interface between subsystems go here.

-/* dllinit.c -- Portable DLL initialization.
-   Copyright (C) 1998 Free Software Foundation, Inc.
-   Contributed by Mumit Khan (khan@xraylith.wisc.edu).
-
-   I've used DllMain as the DLL "main" since that's the most common
-   usage. MSVC and Mingw32 both default to DllMain as the standard
-   callback from the linker entry point. Cygwin32 b19+ uses essentially
-   the same, albeit slightly differently implemented, scheme. Please
-   see DECLARE_CYGWIN_DLL macro in <cygwin32/cygwin_dll.h> for more
-   info on how Cygwin32 uses the callback function.
-
-   The real entry point is typically always defined by the runtime
-   library, and usually never overridden by (casual) user. What you can
-   override however is the callback routine that the entry point calls,
-   and this file provides such a callback function, DllMain.
-
-   Mingw32: The default entry point for mingw32 is DllMainCRTStartup
-   which is defined in libmingw32.a This in turn calls DllMain which is
-   defined here. If not defined, there is a stub in libmingw32.a which
-   does nothing.
-
-   Cygwin32: The default entry point for cygwin32 b19 or newer is
-   __cygwin32_dll_entry which is defined in libcygwin.a. This in turn
-   calls the routine you supply to the DECLARE_CYGWIN_DLL (see below)
-   and, for this example, I've chose DllMain to be consistent with all
-   the other platforms.
-
-   MSVC: MSVC runtime calls DllMain, just like Mingw32.
-
-   Summary: If you need to do anything special in DllMain, just add it
-   here. Otherwise, the default setup should be just fine for 99%+ of
-   the time. I strongly suggest that you *not* change the entry point,
-   but rather change DllMain as appropriate.
