Source/WebCore:

No new tests (No change in behavior.)

Give SharedBuffer the ability to replace its contents from another SharedBuffer:
* platform/SharedBuffer.h:
* platform/cf/SharedBufferCF.cpp:
(WebCore::SharedBuffer:: tryReplaceContentsWithPlatformBuffer):

Forward along SharedBuffer's new ability to ResourceBuffer:
* loader/mac/ResourceBuffer.mm:
(WebCore::ResourceBuffer:: tryReplaceSharedBufferContents):
* loader/ResourceBuffer.h:

Give CachedResource the ability to replace its encoded data buffer if appropriate:
* loader/cache/CachedResource.cpp:
(WebCore::CachedResource:: tryReplaceEncodedData):
* loader/cache/CachedResource.h:

* WebCore.exp.in:

Source/WebKit2:

Add a timer that will try to look up the disk cached buffer for the resource a few seconds after the load
completes and - if the resource is disk backed - send it to the WebProcess for sharing:

Refactor SharedMemory to remove the unnecessary vm_copy and only vm_allocate when an appropriate buffer
doesn't already exist:
* Platform/SharedMemory.h:
* Platform/mac/SharedMemoryMac.cpp:
(WebKit::SharedMemory::create):
(WebKit::SharedMemory::createFromVMBuffer):
(WebKit::SharedMemory::~SharedMemory):

Give ShareableResource the ability to create a CFDataRef that wraps "this", and return it in a SharedBuffer:

(WebKit::createShareableResourceDeallocator):
(WebKit::ShareableResource::Handle::tryWrapInSharedBuffer):
* Shared/ShareableResource.h:

* Shared/WebCoreArgumentCoders.cpp: Encode/decode the cache partition for ResourceRequest.
