This has no effect in the most conventional case, where no relevant DLL
uses a debug build. For an example where it does matter, given a debug
build of MIT Kerberos, the krb_server_keyfile parameter usually had no
effect. Since nobody wants a Heisenbug, back-patch to 9.2 (all
supported versions).

In accordance with its own documentation, invoke CloseHandle() only when
directed in the documentation for the function that furnished the
handle. GetModuleHandle() does not so direct. We have been issuing
this call only in the rare event that a CRT DLL contains no "_putenv"
symbol, so lack of bug reports is uninformative. Back-patch to 9.2 (all
supported versions).

Replace use of plain 0 as a null pointer constant. In comments, update
terminology and lessen redundancy. Back-patch to 9.2 (all supported
versions) for the convenience of back-patching the next two commits.

MSVCRxx runtime, not just the current + Visual Studio 6 (MSVCRT). Clearly
there can be an almost unlimited number of runtimes loaded at the same
time.
Per report from Hiroshi Inoue
Also, if linked against other versions than the default MSVCRT library
(for example the MSVC build which links against MSVCRT80), also update
the cache in the default MSVCRT at the same time.
This should fix the issues with setting LC_MESSAGES on the MSVC build.
Original patch from Hiroshi Inoue and Hiroshi Saito, much rewritten
by me.
