Summary0001291: Separate plugin bridge versions for legacy / buggy plugins

We have observed many plugins which do not (any longer) work in OpenMPT, also not if run in the plugin bridge. Sometimes this is the result of using safer defaults for linker flags, OS compatibility declarations etc.

For example:

  • Many old plugins don't like Data Execution Prevention (DEP) being turned on.
  • Synth1 x64 has problems with Windows 8+ High Entropy Heap. If this flag is disabled, heap allocated addresses are more likely to stay below the 32-bit border, preventing the crash from happening in most situations.
  • Free RS-MET plugin editors crash if OpenMPT declares to be compatible with Windows 10.
  • DPI-awareness of old plugins.

To keep these old plugins alive, we could provide a second "unsafe" set of plugin bridge executables which disables DEP, high entropy heap and does not declare any operating system compatibility. DPI-awareness doesn't need to be handled this way as it can be configured at runtime.
