Customize Lua GC, add object-memory-lock API.
Add custom API to prevent Lua Objects from being garbage collected.
This is intended to for Ardour LuaBridge bindings (~1MB Objects:
tables, functions and userdata).
The bindings are persistent and the gc can skip them in mark & sweep
phases. This is a significant performance improvement for garbage
collection.

Note. The next version of Lua (5.4) will come with a generational-gc
rather than an incremental, so extending the API at this point in time
is acceptable.

Special case Lua copy-construction of trackable instances
This fixes an crashing issue with ArdourUI.SelectionList a bug
introduced in 6dc3bdf252 and 35dcd46d7d.

Since removal of the special cases in 35dcd46d7d, when using
a C-pointer in a std::list<>,
  std::list<class*>::push_back(TypeListValue)
TypeListValues<>'s Head was expanded to  "class*& const"
implied by void ::push_back(const T& value);

This resulted in lifetime issues with a classes that derive
from sigc::trackable (e.g. Ardour's Selection).
The reference leaves scope and isn't duplicated when it is pushed back
to the std::list<>.

The script scripts/select_every_2nd_region.lua crashed because entries
in the SelectionList were no longer valid.

Previously (before 6dc3bdf252) TypeListValues explicitly
copy-constructed the value to work around the lifetime issue.
This new solution bypasses the issue by directly using the c-pointer
without dereferencing it.

520dcf8cdf rework lua-bridge C++ variable references
Since lua functions are closures, C++ methods that pass arguments by
reference cannot be used directly. The previous approach (boost::ref)
failed with clang. Assume the following:

  void foo (float&) { }
  static inline float& bar () {
    boost::reference_wrapper<float> r (42);
    return r.get ();
  }

  foo ( bar () );

With gcc, "r" goes out of scope after foo's arguments are processed
and all is well.
But with clang,  "r" already leave scope when *inlined* bar() returns.

Solution: allocate some user-data on the lua-stack to hold the reference.
There is no reference to this user-data so lua will eventually
garbage collect it.

(theoretically, creating the table which holds the return-values
could trigger an emergency garbage collection when memory is low and
free the reference just while they're being pushed to the table, then
gain FuncArgs<Params> already dereferenced them all as variable on the
C stack -- probably again compiler specific)

44a3f042a7 prepare sharing C++ class instances across lua-interpreters
in particular: lua-lifefime (!) C++ instances.
This allows for dynamic allocation of custom user-data, bound to
the lifetime of the allocating lua-context.
