<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/197372">r197372</a> - Modern IDB: WebKit 2 IPC layer easily confused about multiple web processes being connected.
https://bugs.webkit.org/show_bug.cgi?id=154837
Reviewed by Alex Christensen.
Source/WebKit2:
The crux of the bug is that WebProcesses cannot assign themselves server-unique identifiers...
The server must do that for them.
A once-per-session-per-WebProcess sync message and a few updates to connection management fix this.
