Recreation of the Lua virtual machine

It is possible to “recreate” the Lua virtual machine (lua_State), used by the plugin, i.e: to close the current one and create a new one.

In order to do that the global variable RecreateLuaState should be assigned a true value.
The analysis of RecreateLuaState and the virtual machine recreation are conducted in the OpenW plugin’s exported function, just before returning control to Far Manager.
Prior to the virtual machine recreation the LF_ExitFAR function is called.
After the virtual machine is recreated all actions that normally occur when Far Manager loads a LuaFAR plugin are conducted, including running the plugin’s “starting” Lua script (which in this case receives true as an argument).
After the virtual machine is recreated the global variable IsLuaStateRecreated is set to true.
