This changeset is meant to exemplify how to convert a "namespace" class whose
methods are static -- and whose data are module-static -- to an LLSingleton.
LLVersionInfo has no initClass() or cleanupClass() methods, but the general
idea is the same.
* Derive the class from LLSingleton<T>:
class LLSomeSingleton: public LLSingleton<LLSomeSingleton> { ... };
* Add LLSINGLETON(LLSomeSingleton); in the private section of the class. This
usage implies a separate LLSomeSingleton::LLSomeSingleton() definition, as
described in indra/llcommon/llsingleton.h.
* Move module-scope data in the .cpp file to non-static class members. Change
any sVariableName to mVariableName to avoid being outright misleading.
* Make static class methods non-static. Remove '//static' comments from method
definitions as needed.
* For LLVersionInfo specifically, the 'const std::string&' return type was
replaced with 'std::string'. Returning a reference to a static or a member,
const or otherwise, is an anti-pattern: the interface constrains the
implementation, prohibiting possibly later returning a temporary (an
expression).
* For LLVersionInfo specifically, 'const S32' return type was replaced with
simple 'S32'. 'const' is just noise in that usage.
* Simple member initialization (e.g. the original initializer expressions for
static variables) can be done with member{ value } initializers (no examples
here though).
* Delete initClass() method.
* LLSingleton's forté is of course lazy initialization. It might work to
simply delete any calls to initClass(). But if there are side effects that
must happen at that moment, replace LLSomeSingleton::initClass() with
(void)LLSomeSingleton::instance();
* Most initClass() initialization can be done in the constructor, as would
normally be the case.
* Initialization that might cause a circular LLSingleton reference should be
moved to initSingleton(). Override 'void initSingleton();' should be private.
* For LLVersionInfo specifically, certain initialization that used to be
lazily performed was made unconditional, due to its low cost.
* For LLVersionInfo specifically, certain initialization involved calling
methods that have become non-static. This was moved to initSingleton()
because, in a constructor body, 'this' does not yet point to the enclosing
class.
* Delete cleanupClass() method.
* There is already a generic LLSingletonBase::deleteAll() call in
LLAppViewer::cleanup(). It might work to let this new LLSingleton be cleaned
up with all the rest. But if there are side effects that must happen at that
moment, replace LLSomeSingleton::cleanupClass() with
LLSomeSingleton::deleteSingleton(). That said, much of the benefit of
converting to LLSingleton is deleteAll()'s guarantee that cross-LLSingleton
dependencies will be properly honored: we're trying to migrate the code base
away from the present fragile manual cleanup sequence.
* Most cleanupClass() cleanup can be done in the destructor, as would normally
be the case.
* Cleanup that might throw an exception should be moved to cleanupSingleton().
Override 'void cleanupSingleton();' should be private.
* Within LLSomeSingleton methods, remove any existing
LLSomeSingleton::methodName() qualification: simple methodName() is better.
* In the rest of the code base, convert most LLSomeSingleton::methodName()
references to LLSomeSingleton::instance().methodName(). (Prefer instance() to
getInstance() because a reference does not admit the possibility of NULL.)
* Of course, LLSomeSingleton::ENUM_VALUE can remain unchanged.
In general, for many successive references to an LLSingleton instance, it
can be useful to capture the instance() as in:
auto& versionInfo{LLVersionInfo::instance()};
// ... versionInfo.getVersion() ...
We did not do that here only to simplify the code review.
The STRINGIZE(expression) macro encapsulates:
std::ostringstream out;
out << expression;
return out.str();
We used that in a couple places.
For LLVersionInfo specifically, lllogininstance_test.cpp used to dummy out a
couple specific static methods. It's harder to dummy out
LLSingleton::instance() references, so we add the real class to that test.

LLLoginInstance has a test hook setNotificationsInterface(), used by
lllogininstance_test.cpp to redirect notifications through a dummy
LLNotificationsInterface implementation. Certain of LLLoginInstance's
MandatoryUpdateMachine state classes need to post notifications too; but until
now they directly called LLNotificationsUtil::add(). In the production viewer,
this should (!) be the same as calling through LLLoginInstance::mNotifications
-- but it broke two of the LLLoginInstance unit tests, so they were skipped.
Since MandatoryUpdateMachine's constructor is already passed the invoking
LLLoginInstance&, make it store the reference. Add MandatoryUpdateMachine::
getNotificationsInterface(), which forwards to new LLLoginInstance::
getNotificationsInterface(). Change LLNotificationsUtil::add() calls in
MandatoryUpdateMachine state classes to call through mMachine's
getNotificationInterface() instead.
This allows us to remove #include "llnotificationsutil.h" from
lllogininstance.cpp, also that #include plus stub LLNotificationsUtil::add()
implementation from lllogininstance_test.cpp.
Finally, it allows us to remove the skip() calls from the two unit tests.

The new TUT library build eliminates the ambiguity about ensure_equals(const
char*, ...) versus ensure_equals(const std::string&, ...). Now it's all based
on const std::string&. Remove pointless const char* overloads and ambiguous
forwarding templates.
With clang in Xcode 6, any new datatypes we intend to use with ensure_equals()
must have operator<<(std::ostream&, datatype) declared BEFORE lltut.h
#includes tut.hpp. Reorder code in certain test source files to guarantee that
visibility.

Initial change made LLControlVariable::mPersist an enum, but retained
bool/BOOL public API. setPersist(true) set one value, setPersist(false) set
another, forcePersist() set the third. Per code review, expose enum to public,
make setPersist() (and LLControlVariable constructor, and LLControlGroup::
declareControl(), and all the LLControlGroup::declareMumble() methods, and all
the unit-test dummy declareMumble() method bodies) accept that enum. Remove
forcePersist(). Fix calls to LLControlGroup::declareMumble() accordingly.
Also rename PERSIST_YES to PERSIST_NONDFT, also per code review.

LLControlGroup::declareControl(), declareString() etc. etc. all used to return
BOOL -- which no one ever examines because it unconditionally returned TRUE.
Make it return the (possibly new) LLControlVariable* instead.

Needs to be changed when IE is checked in, of course.
Now we check the expected credential formats for a given grid against the

Neither lllogininstance.cpp nor lllogininstance_test.cpp need llfloatertos.h
any more, since LLLoginInstance talks to LLFloaterTOS only via LLFloaterReg
and LLEventPumps. However, both sources depended on llfloatertos.h dragging in
llnotifications.h, so include that explicitly instead of llfloatertos.h.
