        * NetworkProcess/NetworkConnectionToWebProcess.cpp:
        (WebKit::NetworkConnectionToWebProcess::registerBlobURL):
        (WebKit::NetworkConnectionToWebProcess::registerBlobURLFromURL):
        (WebKit::NetworkConnectionToWebProcess::unregisterBlobURL):
        * NetworkProcess/NetworkConnectionToWebProcess.h:
        Implement BlobRegistry interface by using BlobRegistryImpl (same one as used in
        WebProcess in non-PPT mode).

        * NetworkProcess/NetworkConnectionToWebProcess.messages.in: Added three messages
        needed for BlobRegistry.

        * NetworkProcess/NetworkProcess.cpp:
        * NetworkProcess/NetworkProcessPlatformStrategies.cpp: Added.
        * NetworkProcess/NetworkProcessPlatformStrategies.h: Added.
        Added a mostly empty platform strategy, just for FormData to talk to BlobRegistry.
        Perhaps we'll find a way to avoid this WebCore code path in NetworkProcess, because
        we obviously know which registry implementation is in use in this process.

        * Shared/FileAPI: Added.
        * Shared/FileAPI/BlobRegistrationData.cpp: Added.
        * Shared/FileAPI/BlobRegistrationData.h: Added.
        Added a class for passing BlobData and extension handles over IPC.
        This uses a trick with mutable a member to avoid copying decoded BlobStorageData.

        * WebKit2.xcodeproj/project.pbxproj:
        * WebProcess/FileAPI: Added.
        * WebProcess/FileAPI/BlobRegistryProxy.cpp: Added.
        * WebProcess/FileAPI/BlobRegistryProxy.h: Added.
        A proxy implementation of BlobRegistry that just sends requests over IPC. We only
        need async ones.

        * WebProcess/WebCoreSupport/WebPlatformStrategies.cpp:
        (WebKit::WebPlatformStrategies::createBlobRegistry):
        * WebProcess/WebCoreSupport/WebPlatformStrategies.h:
        Create an appropriate BlobRegistry.
