Invoke R callbacks in pure R

5

Consider rewriting `execCallback` to not invoke R-based callbacks with our own C/C++ code on the call stack. This would remove our invocation of R_TopLevelExec which causes issues with `withCallingHandlers` (like...

[background](https://github.com/s-u/background) pkg allows to schedule callbacks based on file descriptor (and R connections) activity. Would it be hard to add similar mechanism to the `later` pkg?
