As usual, in debugging the creation of a new file with gopls, I've
encountered a go/packages overlay bug. The issue is:
A file b/b.go with package name "b" exists on disk. A package
b/b_test.go with no content exists on disk. There is an overlay for
b/b_test.go that contains the package name "b". Running packages.Load
for file=b/b_test.go will result in a failure to load package b
[b.test]. This change adds this test to the go/packages tests.
This case is fixed by restricting the fallback logic in
runContainsQueries. We only attempt to construct an ad-hoc package if
the original package was returned with no GoFiles.
Also, a minor change to the gopls error parsing code that fixes a case
in which diagnostics were being sent without corresponding files.

The main goal is to push the package variant logic from internal/lsp
into internal/lsp/source so all users of internal/lsp/source benefit.
"references" and "rename" now have top-level source.References() and
source.Rename() entry points (as opposed to hanging off
source.Identifier()). I expanded objectsAtProtocolPos() to know about
implicit objects (type switch and import spec), and to
handle *ast.ImportSpec generically. This gets rid of special case
handling of *types.PkgName in various places.
The biggest practical benefit, though, is that "references" no longer
needs to compute the objectpath for every types.Object comparison it
does, instead using direct types.Object equality. This speeds up
"references" and "rename" a lot.
Two other notable improvements that fell out of not using
source.Identifier()'s logic:
- Finding references on an embedded field now shows references to the
field, not the type being embedded.
- Finding references on an imported object now works
correctly (previously it searched the importing package's dependents
rather than the imported package's dependents).
Finally, I refactored findIdentifier() to use pathEnclosingObjNode()
instead of astutil.PathEnclosingInterval. Now we only need a single
call to get the path because pathEnclosingObjNode() has the
"try pos || try pos-1" logic built in.

In cases like:
var foo *someType = bar.(some<>)
We will now complete "some" to "*someType". This involved two changes:
1. Properly detect expected type as *someType in above example. To do
this I just removed *ast.TypeAssertExpr from
breaksExpectedTypeInference() so we continue searching up the AST for
the expected type.
2. If the given type name T doesn't match, also try *T. If *T does
match, we mark the candidate as "makePointer=true" so we know to
prepend the "*" when formatting the candidate.

This change moves to our ultimate approach of diagnostics the snapshot
on every file change, instead of carefully picking which files and
packages to diagnose. Analyses are shown for packages whose files are
open in the editor. Reverse dependencies are no longer needed for
source.Diagnostics because they will be invalidated when the snapshot is
cloned, so diagnosing the entire snapshot will bring them up to date.
This even works for go.mod files because all of workspace-level `go list`s
will be canceled as the user types, and then we trigger an uncancellable
go/packages.Load when the user saves. There is still room for improvement
here, but it will require much more careful invalidation of metadata for
go.mod files.

Switch the command line client, and its tests, away from the hardcoded
30-second timeout and to a newly-added custom request.
Inconveniently for us, the jsonrpc2 package only serializes requests,
not replies. (Notifications are requests for this purpose.) So, for a
flow like this:
diagnoseFiles -->
<-- publishDiagnostics
<-- publishDiagnostics
diagnoseFiles <-- (reply)
...there's actually no guarantee that the incoming requests will be
processed before the reply comes in -- it gets to jump the
serialization. The only way to guarantee previous notifications have
been processed is to send another request. I didn't feel like adding
nonstandard notification support, so I just send a fake diagnostic.

This change moves as much view initialization code into the
initialization function, instead of having it happen on view create.
Also, the `go env` variables that are collected at inconsistent times
are all collected on view creation. That is sufficient, since the view
is recreated if the environment changes.
I had originally hoped that the initial call to `go env` and the
-modfile detection could become part of this parallel initialization as
well, but you can't create a *packages.Config until the temporary
modfile has been set up, so it still makes sense to do that on view
create. This is, however, the reasoning behind the refactorings in
the -modfile detection in this CL. The main changes are a few renamings
and a split between snapshot.ModFiles and view.modFiles to maximize the
amount of work done in the view. I changed view.modfiles to moduleInformation
because I thought we might want to store additional information there at some
point. Rohan, please let me know if you disagree with any of the changes I made,

Filesystem walks of large GOPATHs/module caches can take seconds,
especially on systems with slow filesystems like MacOS and WSL. We don't
want to block completion requests on walks finishing. At the same time,
cancelling a walk midway through results in an unusable cache, where we
don't know which parts have been scanned so far.
The best option is to run the walks in a separate goroutine. Then we can
detach and let them finish. On the other side, we need to be able to
reattach for the next completion request.
Introduce a new method on caches, ScanAndListen, which first processes
all the items in the cache, then notifies of any new items. This allows
us to reattach to an existing scan without missing anything.
The background scan introduces concurrency to the resolvers where there
wasn't any before. We can't use mutexes, because there's no way to stop
Lock() when a context expires. Use a 1-element semaphore channel to
accomplish the same effect.
Along the way: Only rescan GOPATH if the resolver has been cleared. None
of this makes sense for GOPATH without that. Fix a bug where we were
scanning the main module twice in module mode. Stop loading exports in
module tests, it slows them down a ton.

This change splits source.Diagnostics into source.FileDiagnostics and
source.PackageDiagnostics. There isn't much difference in functionality,
but this just simplifies the process of getting diagnostics if you only
have a PackageHandle.

We were ignoring errors in a few cases and returning incorrect errors in
the case of the command-line interface (no identifier found when there
were just no references). I think it is better for references to return
an error than incomplete results.

This change consolidates the FileKind into only the FileHandle.
Previously, it had been set in multiple places, which required users to
pass in a FileKind when fetching a file. This resulted in confusion,
particularly in places when users did not have access to the file kind.

This isn't a strictly necessary change, but it simplifies things for
open files when the initial workspace load diagnostics come in too late.

This is the first step to surfacing potential fixes and suggestions to a user's go.mod file. Specifically, it will show a warning if you have a dependency that is not used, or if a dependency is declared as indirect when it should be direct and vice versa.
This CL adds functionality for version of Go that are >= 1.14.

We were marking all literal candidates as addressable so we were
getting invalid candidates like "&int()". Fix it to only mark literal
struct, array, slice and map types as addressable.
I also fixed the unnamed literal candidate to pass the dereferenced
expected type. For example, if the expected type was "*[]int" we were
passing a literal type of "*[]int" which wasn't working anymore. Now
we pass "[]int" and take its address as "&[]int{}".

When the tempModfile flag was enabled, there would be some go
commands that would run without the -modfile flag. This change adds
the config's buildFlags to the invokeGo command in go/packages and
updates how we are checking if the go version is 1.14 within the
modfileFlagExists function.
