Need / want Solaris / illumos support

[gdamore]

On illumos/Solaris systems I cannot compile due to many undefined syscall_XXXX warnings. It looks like you generated the values automatically? Any chance I can help with that and get you a pull request?

Yes, as you can see they are generated automatically. And in each of automatically generated files there is a line showing how it was generated: cgo -godefs syscalls.go

But I think right now cgo is available through go tool, So:

Run go tool cgo -godefs syscalls.go on your solaris machine.

So I've been looking at this quite a bit, because it turns out that illumos/solaris lacks also ioctl. Which is silly but ...

I've come up with a quite different approach, that I think will be far superior. It turns out that tcsetattr() and tcgetattr() need to be present as they are required for POSIX compliance (OpenGroup), and are present on all the UNIX like systems (also plan9!) go supports, so we can just change the code to call those directly.

Additionally, there is little or no value in the use of SIGIO and non-blocking IO, or even low level file descriptors. We can make this all work with standard os.File operations, resulting in a simpler read loop.

I'll be sending you a PR shortly that has both these changes -- basically vastly improving portability to UNIX systems, and allowing us to remove the need to predefine syscalls for every UNIX. Stay tuned -- will post this later today.

Ok, this is fixed in PR #99 -- please have a look.
