[svn-r15407] Purpose: Fix bug

Description:
    Changed all subclasses' setId to protected p_setId and put back setId
    in IdComponent.  p_setId is used in the library where the id provided
    by a C API passed on to user's application in the form of a C++ API
    object, which will be destroyed properly, and so p_setId does not
    call incRefCount.  On the other hand, the public version setId is
    used by other applications, in which the id passed to setId needs
    to be closed properly by the application, so setId must call incRefCount
    for the new object to prevent prematurely closing of the id.

Platforms tested:
    Linux 2.6 (kagiso)
    SunOS 5.10 (linew)
    FreeBSD (duty)
