Heschi Kreinick 50c778fb86 internal/imports: redesign scan API ... We have multiple use cases for scanning: goimports, import completion, and unimported completions. All three need slightly different features, and the latter have very different performance considerations. Scanning everything all at once and returning it was not good enough for them. Instead, design the API as a series of callbacks for each directory/package: first we discover its existence, then we load its package name, then we load its exports. At each step the caller can choose whether to proceed with the package. Import completion can stop before loading exports, goimports can apply its directory name heuristics, and in the future we'll be able to stop the scan short once we've found all the results we want for completions. I don't intend any significant changes here but there may be some little ones around the edges.
