Patch by Siddharth Mathur <siddharth.mathur@nokia.com> on 2011-05-16
Rubber-stamped by Csaba Osztrogonác.

Temporarily fix Symbian build by re-enabling compilation
of Qt/Gtk common code (as was the case for Symbian before r55875).
This is a stop gap until the pure Symbian Core IPC and process launching bits land in Bug 55875
As of this revision, only the native SharedMemory implementation is in trunk.

* Platform/CoreIPC/Attachment.h: Compile Qt/Gtk common code for Qt-Symbian too
* Platform/CoreIPC/Connection.h: ditto
* Platform/SharedMemory.h:       ditto
* Platform/qt/SharedMemorySymbian.cpp: stub implementations of attachment handling
(WebKit::SharedMemory::Handle::releaseToAttachment):
(WebKit::SharedMemory::Handle::adoptFromAttachment):
