-------------------------------------------------------------

See the attached diff file.  It should address the problem.

The sslServerHandShakeEvent() function was returning the generic EVENT_CONT instead of SSL_WAIT_FOR_HOOK.  

This meant that the vc was being rescheduled, which caused the CPU spin that Lev obverserved.

In addition, we needed to augment the the SSLNetVConnection::reenable() method to so the readReschedule, so the netvc gets back in the queue when the thread finishes.

> I have created a simple plugin with TS_SSL_SNI_HOOK handler. Handler starts thread. Thread function has small sleep and after that calls TSVConnTunnel.
> The problem is that during sleep duration TS_SSL_SNI_HOOK handler gets continuously called.
> I would expect that TS_SSL_SNI_HOOK handler should be called just once.
> See plugin code in attach.
