f191eec953 internal/lsp: use snapshot to get reverse dependencies
This change modifies the behavior of the GetReverseDependencies function
used for diagnostics. Since we now return diagnostics for the entire
workspace, we don't have to worry if a file is open to show errors in
it. This change requires the addition of a new (*snapshot).PackageHandle
function that gets a CheckPackageHandle for a given package ID. This
function does not cause a re-load of the package metadata, though if we
feel that this is something we need in the future we can add it.

f51c1a7cd2 cmd/godoc: delete unused autocert hooks
The autocert.go file in x/tools was deleted in CL 162400, but some
related variables were left behind. This change deletes them, since
they are unused by now. (If you're feeling déjà vu, it's likely
because this was done in x/website in CL 197957.)

96ad48e4b0 internal/telemetry/export/ocagent: correctly marshal points to JSON
This change adds a custom MarshalJSON func to Point so that values
are formatted the same way jsonpb formats them. This allows the
OpenCensus service to determine the concrete type of the point's
value when unmarshaling.

What works:
* Points with Int64, Double, and Distribution values will marshal correctly.

What does not work:
* Points with Summary values will not marshal.

688c506a55 cmd/godoc, godoc/static: remove remnants of golang.org website
The canonical home for the golang.org website by now is
the golang.org/x/website/cmd/golangorg command. That is
the command that should be used to run the website locally
instead of godoc.

This change reduces the scope of x/tools/cmd/godoc to be
a minimal Go Documentation Server. It removes the remaining
pieces of the golang.org website and changes the title from
"The Go Programming Language" to "Go Documentation Server".

The web tree is modified as follows:

• The index page has been modified to redirect to /pkg/,
  which serves a list of packages.
• The /doc/ tree is removed.
• The /robots.txt and /opensearch.xml pages are removed, since
  the primary use case for godoc now is a local web server.
• The Google Analytics sections are removed from static templates,
  since it's always an empty value in local web server mode.

ad01d5993d internal/lsp: run diagnostics on the entire workspace
This change runs diagnostics on all packages in the workspace, instead
of just open files. We also want to avoid invalidating the type
information for a newly-opened file (since we should have it be default
now), so handle that case.

This causes a large increase in memory usage in the
internal/lsp/cmd tests, so to handle that, share an app between all of
the tests, rather than creating one per-test type.

7f7817c0f9 internal/lsp: handle breakage caused by CL 207598
textDocument/didChange events need to indicate if the change includes
the full file content or just a diff. Previously, the
contentChange.Range field was a pointer, so if it was nil, then we would
conclude that the file change was for the whole file. Now, the best we
can do is compare it to an empty range, but this still doesn't work if
you are at the beginning of a file. I think that the range needs to be a
pointer for this to work correctly.

Also, some minor changes that came up along the way while debugging:
(1) Don't close over the *cache variable for fear of pinning anything in
    memory
(2) Improve the error message when the token.File is nil
(3) Check for a nil token.File earlier

5091d647ee internal/lsp: reorganize the generated Go code for the lsp protocol
Code generation has been unified, so that tsprotocol.go and tsserver.go
are produced by the same program. tsprotocol.go is about 900 lines shorter,
partly from removing boilerplate comments that golint no longer requires.
(And partly by generating fewer unneeded types.)

The choice made for a union type is commented with the set of types. There
is no Go equivalent for union types, but making themn all interface{}
would replace type checking at unmarshalling with checking runtime
conversions.

Intersection types (A&B) are sometimes embedded (struct{A;B;}, and
sometimes expanded, as they have to be if A and B have fields with the
same names.

There are fewer embedded structs, which had been verbose and confusing to
initialize. They have been replaced by types whose names end in Gn.

Essentially all the generated *structs have been removed. This makes
no difference in what the client sends, and the server may send a {}
where it previously might have sent nothing. The benefit is that some
nil tests can be removed. Thus 'omitempty' in json tags is just
documentation that the element is optional in the protocol.

The files that generate this code will be submitted later, but soon.

5a76f03bc7 internal/lsp: fix variadic interface completion ranking
In cases like:

var foo []io.Writer
var buf *bytes.Buffer
foo = append(foo, <>)

we weren't giving "buf" a good score. When comparing the candidate
type *bytes.Buffer to the (variadic) expected type []io.Writer we were
turning the candidate type into []*bytes.Buffer. However, of course,
[]*bytes.Buffer is not assignable to []io.Writer, so the types didn't
match. Now we instead turn the expected type []io.Writer into
io.Writer and compare to *bytes.Buffer.

I fixed the @rank test note to check that the candidates' scores are
strictly decreasing. Previously it would allow candidates with the
same score if they happened to be in the right order. This made it
easier to right a test for this issue, but also uncovered an issue
with untyped completion logic. I fixed it to do the untyped constant
check if _either_ the expected or candidate type is
untyped (previously it required the candidate type to be untyped).

Fixes golang/go#35625.

caa0b0f7d5 internal/lsp/source: add support for references in the same workspace
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.

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
correctly.

77e3bb0ad9 go/packages/packagestest: add package use example
The purpose and value of packagestest is easy to understand. However,
the current API may not be easy to get started with. It includes
identifiers such as Exporter, Exported, Export, whose names may not
make it very clear in what order they are to be used, and whether
the Exporter interfaces needs to be implemented by the caller.

There are fairly common patterns of usage spread out across various
packages that use packagestest. Add an example of basic usage to the
documentation of this package that connects all of the pieces together,
so that users don't have to look for it elsewhere.

I would've preferred to add the example as example code¹, but it
doesn't seem viable to write example code for test helper packages.
There isn't a way to get a functional *testing.T in a func Example.
