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.

to a new llcommon/llinitdestroyclass.h.
This mechanism is so general -- but has so many related moving parts -- that
(a) it deserves to be in a header file all its own, instead of conflated with
llui.h, and (b) it should be in llcommon where anyone can use it. It has no
dependencies whatsoever on llui or anything viewer-specific.
In this very changeset we changed one #include "llui.h" whose comment admits
that it was only dragged in for LLDestroyClass.

renamed LLView::handleVisibilityChange to onVisibilityChange to reflect
standard naming conventions for handlers vs. reactors

- Now chiclet bar adjusts its width with Mini-Location bar

- Removed all sidetray dependencies and the sidetray itself.
- Also removed LLFloaterSidetrayTab and LLSidetrayListener as unused.

Privacy" changes. Many naming changes for the featureto be "See avatars"
instead of "hidden avatars". Also removed the "anyone can edit terrain"
checkbox and slammed the value to FALSE.

Backing out this merge that I pushed (prematurely) to the wrong place.

- Added callback on show\hide Mini Location Panel event. This callback sets proper initial minimized position depending on state (shown or hidded) Mini Location Panel. Also callback shifts vertically already minimized floaters so that they don't overlap Mini Location Panel

Mini-Location bar are mutually exclusive now
- Implemented context menu for Mini-Location bar (menu_topinfobar.xml)
- Implemented function show_topinfobar_context_menu() (in llviewermenu.h) which displays context menu for Mini-Location bar.
- Functions toggle_show_navigation_panel() and toggle_show_mini_location_panel() modified so that Navigation Bar and Mini-Location bar are mutually exclusive (when the former is visible the latter is hidden and vice versa).
- Implemented method LLPanelTopInfoBar::onContextMenuItemClicked which handles \"landmark\" and \"copy\" Mini-Location bar context menu actions.

- Implemented class LLPanelTopInfoBar (llpaneltopinfobar.h, llpaneltopinfobar.cpp, panel_topinfo_bar.xml). Most of it's implementation is borrowed from LLLocationInputCtrl class.
- Mini-Location panel is turned off by default.
- Added top bar context menu option \"Show Mini-Location Panel\".
- Mini-Location panel displays the same context menu as top bar.
- Added code to initialize LLPanelTopInfoBar in llviewerwindow.cpp.
- Added declaration of the widget in main_view.xml
