Instead of using the entire import node as the range for the

better when using a _ or named import, as well as constraining

This change is the first step in centralizing control of modifications
to different files, either within the workspace or outside of it. We add
a source.FileAction type to pass into the internal/lsp/cache package and
handle the difference between opening and creating a file.
Now that we load all packages in a workspace by default, we no longer
need to re-load a file on open. This CL should enable CL 206883 to work

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.

This change implements initial support for viewing Go package
documentation with godoc in module mode. There are no UI changes.
When running the godoc binary in a directory where module mode
is active (i.e., go env GOMOD reports a non-empty path), the
documentation will be shown for packages provided by modules
rather than from the GOPATH workspace.
The mode can be controlled in the same way as the go command, by
changing the GO111MODULE environment variable¹ value. For example,
'GO111MODULE=on godoc' will force godoc to run in module mode, and
'GO111MODULE=off godoc' will force godoc to run in GOPATH mode.
It is implemented by reusing the existing virtual filesystem
abstraction. The main module and all of its dependencies (in
other words, the build list²) are determined by invoking the
go list -m all command in the same directory. An attempt is
made to fill the module cache with any selected module versions
that are not already in the local module cache.
This behavior can be controlled in the same way as the go command,
by setting the GOPROXY environment variable. For example, setting
GOPROXY=off disables downloading of any modules. If any of the
modules could not be fetched, it is printed to stderr and
documentation is shown for all other available packages.

There was a dealock introduced in cl/190737 on all the internal structure
debug pages.
The object getters all protect with the mutex already, it should not also
be done in the outer Render function

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.

We intend to use the GOPATH resolver's results during LSP
autocompletion. That means we have to be able to cache its data, same as
we do for modules. Convert it to use a dirInfoCache.
Cache exports in the dirInfoCache. Along the way, store exports as slices
rather than maps. We don't need the extra structure the vast majority of
the time, and the memory overhead is nontrivial.

Packages that aren't imported in the current file will often have been
used elsewhere, which means that gopls will have their type information
available. Expose loaded packages in the Snapshot, and try to use that
information when possible for unimported packages.

When a user completes rand.<>, propose rand.Seed (from math/rand) and
rand.Prime (from crypto/rand), etc.
Because we don't necessarily have type checking information for
unimported packages, I had to add shortcut cases to a number of
functions around the completion code. Better suggestions welcome.
