libxcb build for zig. Includes libxcb source code which is compiled from source. If you include this library in your zig project and build with `zig build -Doptimize=ReleaseSmall -Dtarget=native-linux-musl -Dcpu=baseline` then it will create a very small (75kb) static executable that is redistributable.\
A minimal example of using this library is available here: [xcb-zig-example](https://git.dec05eba.com/xcb-zig-example/).\
Note that this includes all xcb utilities in the xorg family, see: https://gitlab.freedesktop.org/xorg/lib?filter=libxcb
