           Summary: [BREWMP] Add utility functions to create a BREW
                    instance without local variable declarations.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kwangyul.seo at gmail.com


It is too verbose to create a BREW instance. For example, to create a IFileMgr
instance, it takes three lines:

IFileMgr* fileMgr;
IShell* shell = reinterpret_cast<AEEApplet*>(GETAPPINSTANCE())->m_pIShell;
ISHELL_CreateInstance(shell, AEECLSID_FILEMGR,
reinterpret_cast<void**>(&fileMgr));

This pattern is repeated all over the code, so we need a shortcut here. Add a
template function to create a BREW instance in one line.

IFileMgr* fileMgr = createInstanceBrew<IFileMgr>(AEECLSID_FILEMGR);


This can be nicely combined with OwnPtrBrew.

OwnPtrBrew<IFileMgr> fileMgr(createInstanceBrew<IFileMgr>(AEECLSID_FILEMGR));
