Add FSStream and CFRunLoop bindings

[elcritch]

I used these in dmon-nim and it's running.

I started creating my own macOS utilities before I found Darwin. Would much prefer to collaborate!

Feel free to edit to match your style or whatnot.

Thanks! I will make some styling adjustments/renamings shortly. I'm also going to remove your custom allocator, please implement it elsewhere. Btw, why do you need it?

The FSStream requires passing a CFAllocator which it uses to allocate paths and stuff.

Sure but you can just use the cf default one, or even nil?

Can you? I was porting a C library and didn’t delve into it aside from copying what they did.

If I can use the default or nil it’d be simpler. Won’t cause memory leaks though will it?

As a rule of thumb you use kCFAllocatorDefault, and nil is a shortcut for that. No leaks, as long as you properly release everything. Custom allocators are almost never required in day to day app code.

Ah nice! I'll try that out then.
