    MAINT-5232: Normalize LLSingleton subclasses. · d2c3c2f9
    Nat Goodspeed authored
    A shocking number of LLSingleton subclasses had public constructors -- and in
    several instances, were being explicitly instantiated independently of the
    LLSingleton machinery. This breaks the new LLSingleton dependency-tracking
    machinery. It seems only fair that if you say you want an LLSingleton, there
    should only be ONE INSTANCE!
    
    Introduce LLSINGLETON() and LLSINGLETON_EMPTY_CTOR() macros. These handle the
    friend class LLSingleton<whatevah>;
    and explicitly declare a private nullary constructor.
    
    To try to enforce the LLSINGLETON() convention, introduce a new pure virtual
    LLSingleton method you_must_use_LLSINGLETON_macro() which is, as you might
    suspect, defined by the macro. If you declare an LLSingleton subclass without
    using LLSINGLETON() or LLSINGLETON_EMPTY_CTOR() in the class body, you can't
    instantiate the subclass for lack of a you_must_use_LLSINGLETON_macro()
    implementation -- which will hopefully remind the coder.
    
    Trawl through ALL LLSingleton subclass definitions, sprinkling in
    LLSINGLETON() or LLSINGLETON_EMPTY_CTOR() as appropriate. Remove all explicit
    constructor declarations, public or private, along with relevant 'friend class
    LLSingleton<myself>' declarations. Where destructors are declared, move them
    into private section as well. Where the constructor was inline but nontrivial,
    move out of class body.
    
    Fix several LLSingleton abuses revealed by making ctors/dtors private:
    
    LLGlobalEconomy was both an LLSingleton and the base class for
    LLRegionEconomy, a non-LLSingleton. (Therefore every LLRegionEconomy instance
    contained another instance of the LLGlobalEconomy "singleton.") Extract
    LLBaseEconomy; LLGlobalEconomy is now a trivial subclass of that.
    LLRegionEconomy, as you might suspect, now derives from LLBaseEconomy.
    
    LLToolGrab, an LLSingleton, was also explicitly instantiated by
    LLToolCompGun's constructor. Extract LLToolGrabBase, explicitly instantiated,
    with trivial subclass LLToolGrab, the LLSingleton instance.
    
    (WARNING: LLToolGrabBase methods have an unnerving tendency to go after
    LLToolGrab::getInstance(). I DO NOT KNOW what should be the relationship
    between the instance in LLToolCompGun and the LLToolGrab singleton instance.)
    
    LLGridManager declared a variant constructor accepting (const std::string&),
    with the comment:
    // initialize with an explicity grid file for testing.
    As there is no evidence of this being called from anywhere, delete it.
    
    LLChicletBar's constructor accepted an optional (const LLSD&). As the LLSD
    parameter wasn't used, and as there is no evidence of it being passed from
    anywhere, delete the parameter.
    
    LLViewerWindow::shutdownViews() was checking LLNavigationBar::
    instanceExists(), then deleting its getInstance() pointer -- leaving a
    dangling LLSingleton instance pointer, a land mine if any subsequent code
    should attempt to reference it. Use deleteSingleton() instead.
    
    ~LLAppViewer() was calling LLViewerEventRecorder::instance() and then
    explicitly calling ~LLViewerEventRecorder() on that instance -- leaving the
    LLSingleton instance pointer pointing to an allocated-but-destroyed instance.
    Use deleteSingleton() instead.
