lazyload: use correct calling conventions
Christoph Reiter reported on the Git for Windows issue tracker[1], that
mingw_strftime() imports strftime() from ucrtbase.dll with the wrong
calling convention. It should be __cdecl instead of WINAPI, which we
always use in DECLARE_PROC_ADDR().
The MSYS2 project encountered cmake sefaults on x86 Windows caused by
the same issue in the cmake source. [2] There are no known git crashes
that where caused by this, yet, but we should try to prevent them.
We import two other non-WINAPI functions via DECLARE_PROC_ADDR(), too.
* NtSetSystemInformation() (NTAPI)
* GetUserNameExW() (SEC_ENTRY)
NTAPI, SEC_ENTRY and WINAPI are all ususally defined as __stdcall,
but there are circumstances where they're defined differently.
Teach DECLARE_PROC_ADDR() about calling conventions and be explicit
about when we want to use which calling convention.
Import winnt.h for the definition of NTAPI and sspi.h for SEC_ENTRY
near their respective only users.
