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.

Media
Review #112
This change adds controls that change state based on the selection in the nearby media panel. There are basically 3 sets:
- Time-based
- Web-based ("Normal")
- Disabled
Again, these change based on what you've got selected in the panel

Media focus is still tracked separately from LLSelectMgr (which was a change made during a refactor a while ago), but LLViewerMediaFocus now keeps LLSelectMgr updated with the current media focus when it changes.
Added a special case for media focus to LLSelectMgr::deselectAllIfTooFar(), since it was making the focus ring not show up when media focus was on distant media.

This change completely restructures the media controls XUI
so that it is now more flexible so as to implement mini vs.
standard controls. It also now allows for changes based
on artwork and design still as unyet delivered from 80/20,
as well as any feedback from Brian's user testing.
This is also step 1 of renaming the media "hud" to media "controls"

LLViewerMediaFocus now tracks two separate objects: the currently focused media object, and the media object that's currently being hovered over. It no longer stores smart pointers to either the LLViewerObject or the LLViewerMediaImpl -- it now looks up both by UUID every time they're needed, and fails gracefully if either goes away. This will prevent it from keeping objects from being deleted.
The poorly-understood "mouseOverFlag" has been expunged.
LLViewerMediaFocus no longer uses LLSelectMgr at all. The object to focus on is explicitly passed between LLViewerMediaFocus and LLPanelMediaHUD instead of going indirectly through the selection manager.
LLViewerMediaFocus also no longer interacts with the pick from LLToolPie -- the data it needs from the pick (the object and normal vector) is passed explicitly.
LLViewerMediaFocus::setCameraZoom and LLViewerMediaFocus::getBBoxAspectRatio now have no dependencies on the LLViewerMediaFocus object -- all the data they need is passed in when they're called by the LLPanelMediaHUD. I made them static member functions, but they could be moved to LLPanelMediaHUD or even made into file-scoped static functions. The only reason I didn't do either of those is that it seems like they belong with the LLViewerMediaFocus code as opposed to the HUD.
