Fix compilation with older SDK
Do not use SIZE_T which is not defined in older SDK. There is only size_t
type, so use it instead.
Do not use IMAGE_DIRECTORY_ENTRY_COM_DESCRIPTOR which is not defined in
older SDK. Use IMAGE_NUMBEROF_DIRECTORY_ENTRIES macro for checking if
directory index is valid. In all SDKs is DataDirectory[] array size defined
from IMAGE_NUMBEROF_DIRECTORY_ENTRIES macro.
Cast members in IMAGE_EXPORT_DIRECTORY and IMAGE_DIRECTORY_ENTRY_IMPORT to
DWORD as in older SDK they are defined as PDWORD and compiler throws error
'cannot add two pointers'.

Rewrite function save_err_ptr_str() to not use sprintf()
sprintf() is marked by MSVC as unsafe and suppressing compile warning does
not work. It is still generated on AppVeyor. So rewrite code for converting
pointer number to string via open coded for-loop and do not use unsafe
sprintf() function anymore. New code correctly handles both 32bit and 64bit
variants and does not use any #ifdef _MSC_VER anymore.

Replace VirtualQueryEx() call by GetModuleHandleExA() call
Usage of VirtualQueryEx() call is needed for retrieving HMODULE of passed
function address and it is just an undocumented hack. Based on @rhabacker's
tests it is unstable and does not work correctly.
https://github.com/dlfcn-win32/dlfcn-win32/pull/72#issuecomment-656581418
So replace VirtualQueryEx() call by standard GetModuleHandleExA() function
with special GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS flag which should do
the same thing but it is documented and it is working correctly.

Show "(null)" in error message when passed filname to dlopen() was NULL and error occurred
It does not make sense to pass file variable (which is NULL) to function
save_err_ptr_str() which converts its argument to string. We can call
directly save_err_str() with string value.
Also it is highly unexpected that GetModuleHandle(NULL) call fails.

Fix gcc warning: ISO C forbids return between function pointer and void *
Instead of using compiler specific pragma to disable particular warning,
rewrite code which cast from function pointer to data pointer according to
POSIX dlopen() documentation. This also fix compile warning under MSVC.
According to the ISO C standard, casting between function
pointers and 'void *', as done above, produces undefined results.
POSIX.1-2003 and POSIX.1-2008 accepted this state of affairs and
proposed the following workaround:
*(void **) (&cosine) = dlsym(handle, "cos");
This (clumsy) cast conforms with the ISO C standard and will
avoid any compiler warnings.

Do not include intrin.h file
Include file intrin.h is not needed for compiling dlfcn.c as _ReturnAddress
intrinsic is defined in dlfcn.c manually. Moreover _ReturnAddress is
available only as an intrinsic, there is no function implementation. So
even including intrin.h file does not provide function variant for
_ReturnAddress.
More important, include file intrin.h is not available in older Windows
Driver Kit 7.1.0. So removing usage of intrin.h file makes compilation of
dlfcn-win32 also under these older WDK versions.
