I need to change how structural search interacts with indexed/zoekt search and it is becoming very tricky to work with the code in zoekt.go. After a lot of deliberation, I'm moving all structural search logic and interaction with zoekt to it's own file. This PR is a scaffolding change, there is no change in functionality. Please go through the commits to have an easy time. There are only two overarching changes:
zoekt.go into it's own file search_structural.go
search_structural.go. This is dead code.
No tests, no live functionality changes. I will use the dead code in a follow up PR with the changes that I actually want to make.
