leaphelp() (no argument) shows a list of all LEAP APIs.
leaphelp(API) shows further help for a specific API.
Both forms query LuaListener's LeapListener and report its responses. In
future we might reimplement leaphelp() as a Lua function.
Add LuaState::getListener() method, which checks whether there's a LuaListener
associated with this LuaState and returns a pointer if so.
Add LuaState::obtainListener() method, which finds or creates a LuaListener
for this LuaState and returns its pointer.
Both the above use logic migrated from the Lua listen_events() entry point,
which now calls obtainListener() instead.

help() with no argument lists all our viewer builtins.
help(function, function, ...) shows help text for each named function. Each
argument can be either a string or the function in question (e.g. help(help)).
To support Lua-related text containing line breaks, make LLTextEditor::
pasteTextWithLinebreaks() a public template method. Change the existing
implementation, which specifically accepts (const LLWString&), into its
LLWString specialization. The generic template passes llconvert(arg) to that
specialization, the one real implementation.
Make LLFloaterLUADebug methods call pasteTextWithLinebreaks() instead of
insertText(), which ignores newline characters.
To allow help() to accept an actual function as well as a string name, add a
lookup-by-function-pointer map to LuaFunction. (A Lua function does not store
a name.) Make the constructor store an entry in the new lookup map as well as
in the original registry map.
Change LuaFunction::getRegistry() and getRegistered() to getState() and
getRState(), respectively. Each returns a std::pair, but the first binds
non-const references while the second binds const references.

Extend the LuaFunction::Registry map to store helptext as well as the function
pointer.
Add help text to every existing lua_function() invocation.

We were calling lua_pcall() in such a way as to discard any values returned by
the Lua chunk.
Work around Luau's broken lua_tointegerx(), which unlike vanilla Lua's does
not report whether the value at the specified index is or is not an integer.

Add LuaState::expr() that evaluates a Lua snippet and reports back any result
(or error) left on the stack.
Add LLLUAmanager::runScriptFile() and runScriptLine() overloads that accept a
callback with an (int count, LLSD result) signature. The count disambiguates
(error, no result, one result, array of results). Also add overloads that accept
an existing LuaState instance. Also add waitScriptFile() and waitScriptLine()
methods that pause the calling coroutine until the Lua script completes, and
return its results.
Instead of giving LuaState a description to use for all subsequent checkLua()
calls, remove description from its constructor and data members. Move to
expr() and checkLua() parameters: we want a description specific to each
operation, rather than for the LuaState as a whole. This prepares for
persistent LuaState instances.
For now, the existing script_finished_fn semantics remain: the callback will
be called only when the LuaState is destroyed. This may need to change as we
migrate towards longer-lasting LuaState instances.
Make lua_function(name) macro append suffixes to the name for both the
LuaFunction subclass declaration and the instance declaration. This allows
publishing a lua_function() name such as sleep(), which already has a
different C++ declaration.
Move the Lua sleep() entry point to a standalone lua_function(sleep), instead
of a lambda in the body of runScriptFile().

The intention is to decentralize Luau entry points into our C++ code,
permitting a given entry point to be added to the .cpp file that already deals
with that class or functional area. Continuing to add every such entry point
to llluamanager.cpp doesn't scale well.
Extract LuaListener class from llluamanager.cpp to its own header and .cpp
file.
Extract from llluamanager into lua_function.h (and .cpp) declarations useful
for adding a lua_function Luau entry point, e.g.:
lua_register()
lua_rawlen()
lua_tostdstring()
lua_pushstdstring()
lua_tollsd()
lua_pushllsd()
LuaPopper
lua_function() and LuaFunction class
LuaState
lua_what
lua_stack
