Support OS X

[belm0]

Here are immediate compile errors seen on OS X. Pointing to need for event notification (libevent?) and timer abstractions. There's also a shared issue with OS X pthread_t.

Yes, OSX is not supported yet, quite explicitly so :) It’s part of supporting FreeBSD and its ilk. Truth be told not a priority but I will gladly help sombody to add it (merge PRs, can guide to the relevant man pages etc).

The fireworks during compilation are mildly interesting but thanks for trying ;)

Simply put OSX and *BSD support is more or less the same code. The difference is likely syscall ABI / assortment.

And honestly ‘kqueue’ is looking so much nicer then ‘epool’ from Linux as user-land interface...

Now OSX is supported
