7030249: Eliminate use of LoadLibrary and other clean-ups

[Dmytro Sheyko]

Thanks for cleaning it up.

Couple of questions:

Why we obtain HMODULE for kernel32 this way:

     // get handle to kernel32
     if (GetModuleHandleExW((GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS |
                             GET_MODULE_HANDLE_EX_FLAG_UNCHANGED_REFCOUNT),
                            (LPCWSTR)&CreateFileW, &h) != 0)
     {
         ...


instead of

     handle = GetModuleHandle("kernel32");
     if (handle != NULL) {
         ...

?

Also according to MSDN GetModuleHandleEx requires at minimum "Windows XP" or "Windows Server 2003". It means that we do not support "Windows 2000", right?

Thanks,
Dmytro
