Prebuilt windows release

[MagicfTail]

I am with my current setup not able to run docker, it would thus be really helpful to have a prebuilt windows release available, especially since the current instructions don't work according to some other issues.

I personally do not use windows for audioserve and windows build instruction was provided by kind contributor in #28 - you can try to check with that contributor. As code is now it'll not provide all functionality for sure and basically nothing is guaranteed in windows. Instruction are including just if somebody wants to play with it.
I will keep this issue open as an placeholder is somebody will want to commit some effort to windows compatibility.

#27 even contains some windows build

I have found that rust lang install path has changed from C:\Program Files/ path to user space path,
C:/Users/username/.rustup/toolchains/stable-x86_64-pc-windows-msvc/lib/rustlib/x86_64-pc-windows-msvc/lib
where ffmpeg audio libs to be copied. as described in docs/windows-build.md

AudioServe windoes build was OK.

when executed - several things to do yet:

1. when audioserve.exe is started - it returns error on missing av- DLLs.
   so I have copied those DLLs from shared build of windows FFMPEG, i.e.
   ffmpeg https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n4.4-latest-win64-gpl-shared-4.4.zip contained there in bin'subdirectory

avformat-58.dll   avdevice-59.dll   swscale-6.dll
avutil-56.dll     postproc-56.dll
avfilter-8.dll    avcodec-59.dll    swresample-4.dll

2. renamed those av-* .dll file index as required by the error message

3. entry point function áv_register_all() not found in .exe file
   as mentioned in some of ffmpeg projects - it is deprecated
   Solution: simply I have commented out invocation of it within init()

pub fn init() {
    unsafe {
        ffi::av_log_set_level(ffi::AV_LOG_QUIET);
        // ffi::av_register_all()
    }
}

in crates\media_info\src\lib.rs

audioserve.exe launches without error on Windows 10 64 bit now

@rudifus Thanks, looks promising. Still I'd suspect that not everything will be working as expected. Though I've tried not to use *nix only things (maybe with exceptions of signals on few places) , still I've been kind on relying on how linux works. Definitely need to be tested thoroughly. Do at least unit test worked - e.g. cargo test?
