0d653b92c5 internal/lsp/tests: fix WorkspaceSymbols tests
The tests will not run because there is no workspacesymbol marker.
Therefore, restore testdata used in WorkspaceSymbols tests, and
initialize data so that the tests run even if the target of the marker
is 0.

e4e22f76d0 internal/lsp: support when hierarchicalDocumentSymbolSupport is false
This change adds support when hierarchicalDocumentSymbolSupport is false, this can happen with editors who have not supported textDocument/DocumentSymbol. As a result, these older lsp clients need to recieve []protocol.SymbolInformation rather than []protocol.DocumentSymbol. This change required some changes to internal/lsp/cmd to handle not knowing which type it is receiving, this required manual parsing inside of cmd/symbols.go.

Fixes golang/go#34893

a0897bacdd internal/lsp/cmd: improve flexibility of suggested fixes
This change adds support for passing a span to cmd/suggested_fix.go, originally it would just take the filename and apply all the fixes for that file. Now, it can also take just a span within that file and only apply the fixes relevant to that span.

The //@suggestedfix marker now contains an extra parameter to specify which type of codeaction is expected.

ca8c272a4d internal/lsp/tests: fix reset of golden files

Additionally, add the missing primarymod directory as the update

However, keep the location of summary.txt.golden in the same directory
as the primarymod directory.
As a result, some unnecessary data was deleted.

2529d2857a internal/lsp/tests: standardize testdata folder format
This change standardizes the folder structure for testdata that are used for testing the lsp. In particular, it uses the following format:
- dir
  - primarymod
    - .go files
    - packages
    - go.mod (optional)
  - modules
    - repoa
      - mod1
        - .go files
        -  packages
        - go.mod (optional)

As we can see, any folder inside of testdata should be of this format, where the primary test files with the markers are all located inside the primarymod folder. The modules folder is used to hold any potential dependencies that are used for testing.

A consequence of this change is that we can have one directory separated by folders, where each folder is it's own module, this allows us to use internal/lsp/tests with go.mod files. Now, tests.Load() will return an array of Data objects, where each object corresponds to one of the directories structured above.

b4fe758a9b internal/lsp/source: don't allow mutating DefaultOptions
DefaultOptions was a value type, but held map values. This CL changes it
to a function that returns an Options value that has new instances of
all reference types. It would be better if this function returned a
pointer, but that change ended up being too large. I will need to
refactor handling of options later anyway, in order to support sessions
with differing options for golang.org/issues/34111.

This fixes a race in internal/lsp/tests: internal/hooks/analysis.go
mutates the Analyzers map.

See for example the trybots result at:

c07e1c6ef6 internal/lsp: improve variadic completion
Improve candidate ranking when completing the variadic parameter of
function calls.

Using the example:

func foo(strs ...string) {}

- When completing foo(<>), we prefer candidates of type []string or
  string (previously we only preferred []string).

- When completing foo("hi", <>), we prefer candidates of type
  string (previously we preferred []string).

- When completing foo(<>), we use a snippet to add on the "..."
  automatically to candidates of type []string.

I also fixed completion tests to work properly when you have multiple
notes referring to the same position. For example:

foo() //@rank(")", a, b),rank(")", a, c)

Previously the second "rank" was silently overwriting the first
because they both refer to the same ")".

Fixes golang/go#34334.

eb46839a96 internal/imports: return non-stdlib candidates from GetAllCandidates
Scan most sources, including GOPATH, the module cache, the main module,
and replace targets as appropriate. Use the cached stdlib instead of
scanning GOROOT.

We heavily cache the contents of the module cache, so performance is
decent. But we have to look at all the modules not in the module cache
too to get the right versions of modules (see
(*ModuleResolver).canonicalize), which currently isn't cached at all,
even just for a single run. That ends up being pretty expensive.

The implementation changes are relatively small; add package name
loading to scan(), cache that result, and allow callers to control what
directories are scanned so that it can skip GOROOT.

I also cleared out most of the stdlib from the unimported completion
test and added a simple external completion to it for safety's sake.

5adc67163c internal/lsp: improve completions in *ast.FieldList
Now we always expect type names inside of *ast.FieldList. This expands
the previous func signature logic to also work for *ast.StructType
and *ast.InterfaceType. For example, we will now prefer type names in
cases like:

type myStruct struct { i i<> }

Also, fix a check for anonymous fields to make sure the field is
actually embedded. This fixes cases like this to properly have no
completions:

type myStruct struct { i<> i }

where this will still give type name completions:

type myStruct struct { i<> }

I introduced a new error type source.ErrIsDefinition so source_test.go
could avoid erroring out on tests that make sure definition
identifiers have no completions.

Fixes golang/go#34412.

a044388aa5 internal/lsp: add literal completions for basic types
Normally you don't want literal candidates for basic types (e.g.
"int(0)") since you can type the literal value without the type name.
One exception is if you are creating a named basic type that
implements an interface. For example:

http.Handle("/", http.FileServer(<>))

will now give "http.Dir()" as a candidate since http.Dir is a named
string type that implements the required interface http.FileSystem.
