libmpq is a much simpler alternative to StormLib for reading MPQ archives. We use our own fork of libmpq: https://github.com/diasurgical/libmpq Impact: * DevilutionX is now a lot more portable. Unlike StormLib, libmpq only needs platform-specific code for Windows. * Locks around file access **removed** (instead we duplicate the file descriptor for streamed audio only). * RAM usage is **300 KiB** lower than StormLib. * Stripped release linux_x86_64 binary is **32 KiB** smaller. * Amiga build now hangs instead of crashing.
