libev out of context thread

[Varun Chandramohan]

Hi Marc,

Thanks for the reply. Not sure why the code formatting is weird. I started
using async watchers and it helped. I got it working with that. I did
remove one other thread as I felt it was not needed with async watcher.
My solution is to use thread 1 to read from socket a packet add it to queue
and immediately notify the async watcher of data available. I also added
mutex lock to avoid race condition. Everything seem to be working well
as expected. I have currently put the code under stress test. Thanks for
the help.

Regards,
Varun
