[Qt][WK2][Symbian] Shared memory implementation for Symbian
​https://bugs.webkit.org/show_bug.cgi?id=55875

Use global chunks for sharing data between processes.
This is an initial implementation. An outstanding issue
is the correct way to close() the chunk in the SharedMemory d'tor
without triggering a delete by the kernel when the ref-count
temporarily goes to zero.

• Platform/SharedMemory.h: platform specific handle and chunk name
• Platform/qt/SharedMemorySymbian.cpp: Added. Native Symbian OS implementation using RChunk.CreateGlobal() for named chunks. The chunk name is serialized and sent over the IPC channel and opened by the remote process using RChunk.OpenGlobal().

(WebKit::SharedMemory::Handle::Handle):
(WebKit::SharedMemory::Handle::~Handle):
(WebKit::SharedMemory::Handle::isNull):
(WebKit::SharedMemory::Handle::encode):
(WebKit::SharedMemory::Handle::decode):
(WebKit::SharedMemory::create):
(WebKit::SharedMemory::~SharedMemory):
(WebKit::SharedMemory::createHandle):
(WebKit::SharedMemory::systemPageSize):

• Platform/unix/SharedMemoryUnix.cpp: Exclude Qt-Symbian using HAVE(UNIX_DOMAIN_SOCKETS)
• WebKit2.pro: Add SharedMemorySymbian.cpp
