Specifically:
* Added win32, elf32 and elf64 asm player and wav writers using winmm.
* Added dsound player in C.
* Separated the ALL target and the examples; introduced a new examples target.
The RPC and sync library mechanisms were removed for now; they never really worked and contained several obvious bugs. Need to consider if syncs are useful at all during the compose time, or just used during intro.
There is a new "sync" opcode that saves the top-most signal every 256 samples to the new "syncBuffer" output. Additionally, you can enable saving the current fractional row as sync[0], avoiding calculating the beat in the shader, but also calculating the beat correctly when the beat is modulated.
The working principle is similar as before with x86, but instead of outputting .asm, it outputs .wat. This can be compiled into .wasm by using the wat2wasm assembler.
Nasm gives warnings about labels without colons in the end; these were particularly prevalent in struc members: ".size" has be ".size:". Nasm also wasn't happy with extra trailing commas when calling macros.
The bridge.go now just assumes that the library you want is built in the build/ directory. It's probably a lot better idea than using wherever the latest build was; this way the same build is always used for the library.
Builds on both 32-bit and 64-bit executables and all tests (except gm.dls stuff obviously, which was excluded) pass on 64-bit Linux. Cannot test the 32-bit executables, as WSL does not support running 32-bit.
The implentation is through a few macros to handle the fact in 64-bit, all addresses have to be loaded first to register and only offsets are ok. Also, push only supports 64-bit registers in 64-bit, so we have _AX, _BX, _CX etc. defines, which are eax, ebx and ecx on 32bit and rax, rbx and rcx on 64bit.
