Currently, we deep search top level candidates as soon as they're found,
which isn't necessarily leading to an overall breadth first search
approach. This change refactors completion to add candidates to search
queue instead and only call deepSearch once at the end.

Add a new field to the options JSON, EnumValues. Use it to automatically
generate the documentation for enums. Fix the displayed type to be
"enum" rather than the full-qualified Go type name.
To make this easy, I changed the various enum constants to be strings,
with values matching their configuration values. It may be possible to
automatically parse them in the future, but we can get to that later.
The documentation for hoverKind's private values is a little janky. I
didn't want to build a way to hide them. We can hardcode it if we really
care.

1.16 wants to set GO111MODULE=on. There are, AFAIK, two differences
between "auto" and "on". First, if you're in a directory outside of GOPATH
and with no go.mod, "on" will run in module mode with GOMOD=os.DevNull.
I don't think we care very much about that. Second, if you're in GOPATH
with no go.mod, "on" will run in module mode, breaking GOPATH mode.
Breaking GOPATH mode may be desirable for the go command generally, but
for gopls I think it will lead to an unnecessarily bad user experience.
Users will find out when they do their first build or test; there's IMO
no need to also break their editor.
Flip the default back to "auto".

GO111MODULE=off in ProcessEnv but not in the current process's

Context allows the user to set GOPATH, GOOS, GOARCH, and a few other
environment variables, but not GO111MODULE. Context.Import may return
different results than packages.Load if the latter is invoked with a
GO111MODULE value that differs from the caller's environment. Setting
an I/O hook forces Import to run in GOPATH mode, not invoking 'go list'.
This is undocumented, but it should be stable while GOPATH is

Go 1.16 may set -mod=readonly by default. To maintain current behavior,
gopls needs to override that by passing -mod=mod to all its go
invocations.
While this behavior should be safe on all modern versions of Go, I gated
it on 1.16 just for safety's sake.

This change adds an experimental configuration, which when enabled,
shifts gopls to operate in multi-module mode. It implements the
super-module as described in
https://github.com/golang/proposal/blob/master/design/37720-gopls-workspaces.md.
Replace directives are also added when a workspace module requires
another workspace module (which has not yet been mentioned in the design
doc).
A user-provided workspace gopls.mod file is not yet supported, as it is
not yet testable. Clients will need to add support for change
notifications for the gopls.mod once it is added.

The logic to de-dupe workspace symbols was broken in two ways:
- The 'seen' map of files already processed was never written.
- The key to 'seen' was *ast.File, which doesn't work if we parse
twice.
Fix this by de-duping instead on span.URI.

Build tags are a common stumbling block for users of gopls, as build
tagged files may be excluded from the initial workspace load without a
clear warning. This change adds a check for every opened file to confirm
if it maps to a package. If not, we show a message with suggestions.
A follow-up improvement might be to check if the opened file actually
has build tags to make the error message more precise (and give a better
example config).

I missed that this test was failing when fixing the 1.12 build, because
I forgot that I moved the regtests to the gopls module. Hoisted by my

Gopls needs to use the right go command to work properly on a source
distribution. One way of getting this done is by setting go.alternateTools.

Something about the ordering of `go list` results must have changed in
Go 1.15, so overlays with test variants were failing to get the correct
imports. Technically, the correct solution would have been to support
overlays for a package *and* its test variant, but for the purposes of
gopls, it's actually more important that the overlays apply to the
package itself (rather than its test variant).

gopls has many settings. We want to automatically generate
documentation, and we want to allow clients to perform their own
validation if they so desire.
Using all three of AST, type information, and reflection, generate a
JSON description of the settings and their default values. Add a gopls
command that prints it. Add a documentation generator that uses it to
write settings.md.
I assumed that everything not explicitly documented was experimental,
and moved it into that section. I also moved expandWorkspaceToModule to
experimental; I hope it's not long for this world, personally.
Along the way, rename many fields, make the enum matching case
insensitive, and add a stringer call so that the defaults print nicely.
Fixesgolang/go#33544.
