* Simplify get_goroutine_id() implementation, this reduces a map
and thus reduces runtime memory comsumption.

This patch removes the old error-prone way of tracking
whether the tracepoint is for a function entry or
return. Instead of trying to guess, let the data structure
simply tell us directly.
Add some dummy go files so that 'go mod vendor' works for modules that
require Delve, becuase directories that do not contain any go code will
not be vendored.
