[PATCH 0/1] MR1498: ntdll: Use RTLD_NOLOAD to find already mapped modules.

[Rémi Bernon (＠rbernon)]

This makes it possible to detect modules that weren't unmapped from
dlclose, and that we should not fixup again.

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=49640

This usually happens with C++ winelibs, where some C++ symbols may
be inlined into the winelib, then later resolved in preference over
other symbol definitions when libstdc++ loads.

This results in circular dependency between the winelib and libstdc++,
making dlclose no-op.

In this case, reloading the lib later and calling `map_so_dll` on it
again will fixup the RVAs again, ending up with invalid addresses.
