Dump locals of C functions

[devurandom]

STP currently does not dump locals of C functions. When debugging those written using the Lua C API, it sometimes happens that the stacks looks different from what I expected. In these cases I would love to use STP to tell me about the stack.

The fix is simple:

Locals of C functions? Do you have an example of this change in action?
I don't really understand how would that work.
