fix warning : incompatible pointer types passing 'int *' to parameter of type 'LPDWORD' (aka 'unsigned long *') [-Wincompatible-pointer-types]

The rest of the PR cares about deprecation warnings like

..\Modules\socketmodule.c(6070,9): warning : 'gethostbyname' is deprecated:Use getaddrinfo() or GetAddrInfoW() instead or define _WINSOCK_DEPRECATED_NO_WARNINGSto disable deprecated API warnings [-Wdeprecated-declarations]

using the already existing infrastructure_Py_COMP_DIAG_PUSH et al. frompyport.h, because clang-cl unfortunately does not (yet) respect

# defineSUPPRESS_DEPRECATED_CALL __pragma(warning(suppress: 4996))

Is there another way to spell the pragma that will work? The idea ofpyport.h is to deal with compiler differences as much as possible, so it's the place to handle it if the original macro can be made to work.

clang-cl does not understandsuppress, hence I need to push and pop and thus used the existing infrastructure frompyport.h (warning(disable: 4996))

Likewise, AFAIK, there is nosupress in gcc / "regular" clang, so we need to always push / pop there.

nit: Two space indents of preprocessor directives might be uncommon in CPython except when a line starts with#.

I indented everywhere by two spaces to easier spot the macros, but I will happily indent by four spaces if this is preferred.

I'd prefer to avoid thinking of the intention when reading, so +1 for four spaces.

Done. I had a look at the other occurrences in the code base: either no indentation or like the code they guard.

I switched to the latter.
