[PATCH] Core: configurable listening try number

[Han Cheng]

Hello, Maxim,

As I'm new to nginx, please point out if I'm wrong.

The reason why we should have multiply tries is we may fail when we bind().
That is because the address and port
are in use(temporary which  caused by unclean close or others, permanent
like another nginx is using) or others.

In the temporary use case, we may wait and retry. Configurable retry make
us more probable succeed in that case.

By the way, one other TODO in the source code is the configurable wait
time. I think we do not need it when we have
retry.

Anyway, in most cases, we succeed in the first try and go on.

Thanks
