Overview
Comment:* tlsIO.c: Restore the previous version. Fixed the CloseProc so it unregisters the channel handler on the superceded channel instead of the upper channel. Also removed the call to Tcl_NotifyChannel in the ChannelHandler because this will result in an infinite loop if data is ever buffered in the BIO structure. [Bug: 5623]

Moved ChannelHandler to the main channel instead of using Tls_GetParent and registering the handler with the dummy, or stacked channel. Eliminated call to Tcl_NotifyChannel from the WatchProc check-in: b29663e789 user: welch tags: trunk
