Replacing use of ::select in favor of ::poll

[johnjanthony]

Replacing use of ::select() with ::poll() in SSL_SOCK_Connector and SSL_SOCK_Acceptor - on systems that support ::poll(). This is primarily to allow for more than 1024 connections.

These changes look good to me.

@shuston @johnjanthony as the bugzilla issue suggests, wouldn't this change be easier when using ACE::handle_ready which handles the select/poll selection?

[jwillemsen]

In #1145 I changed the flags of ACE::handle_ready to be bool instead of int

[shuston]

It would be easier, I agree. I don't have funding or spare time to work on it.
Also, side note... since the ACE_handle_ready API changed, would this need to be in a 6.6.0?

We are reverting this PR for the moment, see #1146, it has to be improved to keep the code clean, see #1147 for the links to related issues and suggestions to keep this code clean. @johnjanthony can you work on a new PR with the clean changes?
