The Elgato Stream Deck plugin older than 5.5.2.0 invokes undefined
behavior that results in application crashes. Let's block older versions
to prevent the crashes.
This is actually a MainConcept redistributable and not related to Adobe.
Unfortunately Elgato Game Capture HD software relies on this dependency
when presenting the DirectShow device to OBS, so we unintentionally
blocked it from loading.
Instead of outright blocking, we now block only older versions than the
version shipped by Elgato, which has hopefully been patched to fix the
random crashes.
Adds a NtMapViewOfSection hook which we can use before DLLs are loaded
to decide whether to abort the process. This is useful for blocking
known problematic DLLs that cause crashes. In addition, the PE timestamp
can be checked to block only older DLLs such as older versions of Vtuber
virtual cameras with known deadlock bugs.
A simple counter of each DLL is used for logging purposes. Since DLLs
can be blocked at any time, the output is only logged on exit of OBS.
