Use (undocumented) Mix_LoadMUS_RW to load music

mutatis mutandis

some CMake cleanup

We need custom script loading function in lua now

up android target api (but this commit is actually just to test buildbot: desync

fix build

Keeping bruteforce

another tweak tomake --stats-only work on headless servers

and install it too

Oops, didn't realize FindLua.cmake is our own module

Don't rely on hedgehog facing direction, check intentions instead. Should fix excessive turns around and weird jumps to water

comments and runtime list of files to convert and compile

Implement reader in C ffs

Pretend AI knows how to use drill rocket (actually has no idea of drilling)

finally hwengine in c links without errors

Script loading via physfs which doesn't work: - Some scripts just refuse to load for no obvious reason - Some scripts load fine when you set BUFSIZE to a large value, like 64k, but don't load with small values Error messages in both cases don't seem to have relation to lua file contents

Call fallers less often. Should hopefully still be about as effective at the intended purpose. Should help loads quite a bit.

cmake linking for engine in c

Engine loads fine with basic config

make stats-only mode work headless. also skip a few things to save time/memory.

merge xymeng's gsoc engine with a few updates (and further checks on symbol definitions)

Get rid of Pathz and UserPathz

oops

better clang search

- Add physfsrwops library - Load images via physfs (crashes)

Don't accept in-room flags when not in room

merge xymeng pas2c

merge with default
