Add DPI support for statbar
Move heart+bubble bar to Lua HUD
Add statbar size (based upon an idea by blue42u)
Add support for customizing breath and statbar
This makes a number of changes:
* Remove the dependency on marshal by using string.dump and loadstring.
* Use lua_tolstring rather than having Lua functions pass string lengths to C++.
* Move lua_api/l_async_events.* to cpp_api/s_async.*, where it belongs.
* Make AsyncWorkerThread a child of ScriptApiBase, this removes some duplicate functionality.
* Don't wait for async threads to shut down. (Is this safe? Might result in corruption if the thread is writing to a file.)
* Pop more unused items from the stack
* Code style fixes
* Other misc changes
Don't use TOSERVER_RECEIVED_MEDIA but TOSERVER_CLIENT_READY as indicatio for client ready

Add access to statistics information (peer connction time,rtt,version)
Fix clients standing stalled in world while preloading item visuals (new clients only)
Add get_player_information to read client specific information from lua
This reverts commit 362ef5f6ce.
Stack tracebacks couldn't be generated in LuaError::LuaError anyway and this
caused a second, empty traceback in most cases. In cases where there wasn't
annother traceback the stack had already unwound and the traceback was empty.
MapgenParams is no longer a polymorphic class, eliminating the need for messy and bug-prone reallocations.
Separation between the common and mapgen-specific parameters is now strongly defined.
Mapgen parameters objects are now properly encapsulated within the proper subsystems.
