This change moves the module-related fields from the view into the

This change improves the labels for import suggestions to only show the
last part of the path. Since VSCode fuzzy searches for labels in text
edit, we now return only the last part of path as text edit instead of
replacing the full import path. Just changing label while returning full
path leads to bad user experience.

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".

This CL does not fix failures in ./gopls/internal/regtest, which will
be fixed separately.
In refactor/rename.TestDiff, add a go.mod file.
In internal/imports.ProcessEnv.buildContext, set an I/O hook if
GO111MODULE=off in ProcessEnv but not in the current process's
environment.
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
supported.

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.

This change adds one more test for package completions (and slightly
modifies the way we pass in file content without a terminal newline).
Also, a few tiny modifications to the package completion code.

Broke a.go into a few files (no real logic to it). These tests could be
categorized better, but it's a good start just to break up that huge
golden file.

I think we had discussed making this change after you finished your
cache rewrites, but I never got back to it. Let me know if you think
there's a better way to do this.

This CL creates a struct that simplifies some of the extract function
logic. Also, add a test for extraction with an underscore in the
selection (Josh mentioned that this might not work, but it seems too).

Completion is slowly becoming a large part of internal/lsp/source and it
makes sense to move to its own seperate package inside source to make
future refactors easier. As a part of this change, any unexported
members from source required by completion are now exported. Util
functions only required by completion are moved from
internal/lsp/source/util.go to internal/lsp/source/completion/util.go.

It's useful to be able to switch between case sensitive, case
insensitive, and fuzzy matching for symbol without having to reload
gopls. FZF has some nice syntax for this:
https://github.com/junegunn/fzf#search-syntax
Adopt a subset of this syntax for our symbol search:
' for exact matching
^ for prefix matching
$ for suffix matching
It would be straightforward to also support inversion, using
'!', but I deemed this unnecessary.
I think we should adopt this, since none of these symbols conflicts with
Go identifiers, or (AFAIK) with special syntax in major LSP clients.
