2bb19ccf08 reordering of some functions + cleaner way to code lua_resume/resume + 
small bug in lua_resume (in case of calling errors lua_resume should
remove only new arguments from the stack and push error message).

b0f2b288a6 new scheme for debug info about tail calls: no more 'fake' stack entries,

therefore saving C stack space

__gc MetaMethod)

e091a254df new way to GC stacks: the entire stack must be correct all the times; 
the 'dead' part of a stack (after the top) must have only nil's, so
that 'top' may go up without cleaning the stack.

e5249b9fb5 'exit' changed to 'abort' in case of panic (+ some extra comments) 
'abort' seems more in line with panic ("abnormal termination")
