When looking for references, look in the entire workspace rather than
the same package. This makes the references query more expensive because
it needs to look at every package in the workspace, but hopefully
it shouln't be user-noticable. This can be made more efficient by only
checking packages that are transitive reverse dependencies. I don't think a
mechanism to get all transitive reverse dependencies exists yet.
One of the references test have been changed: it looked up references
of the builtin int type, but now there are so many refererences that
the test too slow and doesn't make sense any more. Instead look up
references of the type "i" in that file.

If a user is typing fast, they will quickly invalidate many snapshots.
We don't want to stack up a bunch of stale type check and analysis
operations, so we should propagate cancellation through the cache.
Handles are long-lived, so we may cancel an operation only to
restart it again later. Also, there may be multiple operations waiting on
the same computation, and just because one is cancelled doesn't mean we
should necessarily stop. The easiest way to support all that was to add
an explicit state to each handle, and track the number of waiters.
See the code for more details on Handle life cycles.
As far as I can tell, the rest of gopls is prepared for this behavior.
I added an explicit check to the type checking code, where I was worried
it might get overly confused. But long-term it would probably be good to
return an error from Get.

Previously we were erroneously suggesting a "func() {}" literal in
cases like:
http.Handle("/", <>)
This was happening because saw that the http.HandlerFunc type
satisfied the http.Handler interface, and that http.HandlerFunc is a
function type. However, of course, you can't pass a function literal
to http.Handle().
Make a few tweaks to address the problem:
1. Don't suggest literal "func () {}" candidates if the expected type
is an interface type.
2. Suggest named function types that implement an interface. This
causes us to suggest "http.HandlerFunc()" in the above example.
3. Suggest a func literal candidate inside named function type
conversions. This will suggest "func() {}" when completing
"http.HandlerFunc(<>)".
This way the false positive func literal is gone, and you still get
literal candidates that help you use an http.HandlerFunc as an
http.Handler. Note that this particular example is not very compelling
in light of http.HandleFunc() which can take a func literal directly,
but such a convenience function may not exist in other analogous
situations.

Loading completion suggestions can be slow, especially in GOPATH mode
where basically anything can change at any time. As a compromise, cache
everything for 30 seconds. Specifically, after a completion operation
finishes, if the cache is more than 30 seconds old, refresh it
asynchronously. That keeps user-facing latency consistent, without
chewing up CPU when the editor isn't in use. It does mean that if you
walk away for an hour and come back, the first completion may be stale.
In module mode this is relatively benign. The only things the
longer caching affects are the main module and replace targets, and
relevant packages in those will generally be loaded by gopls, so they'll
have full, up-to-date type information regardless.
In GOPATH mode this may be more troublesome, since it affects
everything. In particular, go get -u of a package that isn't imported
yet won't be reflected until the cache period expires. I think that's a
rare enough case not to worry about.
