79f01bc889 Initial changes needed for building Mixbus (with MSVC) as version 5 
(Mixbus itself will probably need extra changes)

f2ca0c144b 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.

4a180e68ba Special case const std::string& Lua binding. 
since 6dc3bdf, a const string reference would leave scope with Lua code
     fn("text")
calling a C++
     fn (const std::string&)
before the C++ function is called.

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.

a2f249d1d7 tweak lua gc 
lua C++ bindings require ~400KB worth of tables now; so bump memory
available to rt-safe scripts (full interpreter) to 2MB.

Also switch to incremental GC.

Casting std::map::count to the correct type instead of a fake void()

8002b2d26e special case luabridge for windows/MSVC 
luabridge uses static fn addresses to identify classes.
Windows uses different addresses for *identical* static functions
in libardour.dll and ardour.exe

This solves the issue by moving the all functions from a
header-only implementation into libardour.
