Some new stuff on github

I updated some of my github stuff recently.

First, I added SNI support to lophttpd for better supporting
virtual hosting with TLS. Its straight forward to use. Please
refer to the updated README.

Next, I pushed my POSIX realtime AIO implementation for
Linux to github. The glibc aio implementation is creating
an own thread for each aio_read/write that you submit,
not utilizing the kernels io_ syscalls. Clearly, for a large number of AIO contexts this performs badly to not at all.
I am using the io_ syscalls and an event-fd to get
notified about operations that became ready. I also
made sure that it works on Android. :p
